Phase change materials (PCMs) are ideal for thermal management in miniaturized and integrated electronic devices. However, developing PCMs with efficient thermal management and electromagnetic interference (EMI) shielding has remained a challenge to keep up with the rapid evolution of precision electronics. Herein, melamine foam (MF) was used as a template to build a continuous thermal/conductive network by dip-coating magnetized nickel (Ni)/MXene (NiM), and then, polyethylene glycol (PEG) was encapsulated into porous NiM/MF hybrid sponge via vacuum impregnation method. With the synergistic effect of magnetic Ni chain and highly conductive MXene, the obtained NiM/PCM achieve suitable thermal conductivity (0.39 W/mk), high electrical conductivity (76.3 S/m), and excellent EMI shielding effectiveness (34.6 dB). In addition, the NiM/PCM endows outstanding thermal stability, durability, and high latent heat storage capabilities. This work provides new ideas and insights for the EMI shielding and temperature protection of future microelectronic devices. Graphical abstract

The leakage of organic phase change materials (OPCMs) at temperatures above their melting point severely limits their large-scale application. The introduction of porous supports has been identified as an efficient leakage-proofing method. In this study, a novel carbonized Cu-coated melamine foam (MF)/reduced graphene oxide (rGO) framework (MF/rGO/Cu-C) is constructed as a support for fabricating stabilized multifunctional OPCMs. MF serves as the supporting material, while rGO and Cu act as functional reinforcements. As a thermal energy storage material, polyethylene glycol (PEG) is encapsulated into MF/rGO/Cu-C through a vacuum-assisted impregnation method to obtain PEG@MF/rGO/Cu-C composite with excellent comprehensive performance. PEG@MF/rGO/Cu-C exhibits high phase change enthalpies of 148.3 J g −1 (melting) and 143.9 J g −1 (crystallization), corresponding to a high energy storage capability of 92.7%. Simultaneously, MF/rGO/Cu-C endues the composite with an enhanced thermal conductivity of 0.4621 W m −1 K −1 , which increases by 463% compared to that of PEG@MF. Furthermore, PEG@MF/rGO/Cu-C displays great light-to-thermal and electric-to-thermal conversion capabilities, thermal cycle stability, light-to-thermal cycle stability, and shape stability, showing promising application prospects in different aspects.

Polymer-based thermal interface materials (TIMs) have been widely used in electronics to enhance heat transfer through the chip to heat sink. However, it remains a severe challenge to build the efficient phonon transfer pathways for improving the thermal conductivity and heat dissipation ability to cope with the increasing power density. Nowadays, TIMs with introduced template have attracted a great deal of attention because of the continuously three-dimensional (3D) structures. Herein, the reduced graphene oxide (rGO) with 3D networks was fabricated through the self-sacrificing template of melamine foam. Meanwhile, the reduced graphene oxide/natural rubber (rGO/NR) TIMs were prepared by the vacuum-assisted infiltration approach. As a result, the obtained TIMs exhibited the improved thermal conductivity (1.53 W m −1 K −1 ) and the good electromagnetic interference (EMI) shielding performance (26 dB) in X band at the filler content of 1.15 vol%. The results proved that rGO/NR TIMs successfully achieved the balance performance between the thermal conductivity and EMI shielding performance, indicating a bright prospect in the application of next-generation electronics. More importantly, this strategy can provide valuable guideline for designing TIMs with the excellent comprehensive performance for the thermal management. Graphical abstract

The single function and leakage of organic phase change materials (OPCMs) used alone considerably limit the scope of their large-scale applications. An efficient method of addressing this issue is by adding functional fillers and porous scaffolds to OPCMs. In this study, a novel CuS-coated carbonized melamine foam (CMF)/reduced graphene oxide (rGO) framework (CMF/rGO/CuS) was developed for the preparation of stable multifunctional OPCMs. The functional materials rGO and CuS were used as reinforcing materials, and CMF was used as a supporting material. Paraffin wax (PW), a thermal storage substance, was encapsulated in the CMF/rGO/CuS framework by vacuum-assisted impregnation to obtain a PW@CMF/rGO/CuS composite with excellent comprehensive properties. When the concentration of the conductive filler CuS was 2.0 wt%, the conductivity of the PW@CMF/rGO/CuS 2.0was 73.7 % more than that of pure PW, and its photothermal conversion efficiency exceeded 90 %. Meanwhile, CMF/rGO/CuS endowed the composite with a thermal conductivity of 0.2525 W m −1 K −1 , which was 33.6 % higher than that of pure PW. Finally, PW@CMF/rGO/CuS demonstrated high thermal cycling and thermal cycling stability with good application prospects in various fields.

The high viscosity and low fluidity of crude oil impede its adsorption by porous sorbents, making the effective cleanup of crude oil a significant challenge. Herein, inspired by the nano-structure of moth eyes, we developed a hierarchical adsorbent material via electrochemically polymerizing polypyrrole nanowire arrays (PPy NWAs) onto melamine foam (MF), where 1D ordered PPy NWAs were vertically grown on the 3D MF skeleton. The aligned PPy NWAs enhanced hydrophobicity (water contact angle of 151.0°) and served as numerous capillary tubes, thereby achieving 81.0 g g−1 oil adsorption. Due to the continuous PPy network, the MF@PPy foams exhibited a remarkable light-trapping effect with a high light absorption ratio of 98.8% and good electrical conductivity of 201 S m−1. The surface temperature could quickly reach 85.5 °C under simulated illumination (1 sun) and 88.1 °C with a power input (2 V). Interestingly, the photothermal and superhydrophobic effects induced Marangoni flow, leading to controllable light-driven motion. Furthermore, the MF@PPy foams could be remotely operated, allowing for the sustained removal of crude oil from water surfaces via light-activated and pump-assisted systems. This work provides new insights for developing oil adsorption materials by constructing moth-eye structured PPy NWAs, demonstrating great potential for all-weather crude oil adsorption.

Phase change materials (PCMs) can efficiently absorb and release energy while keeping the temperature constant, and thus exhibiting great potential in thermal management applications. However, issues such as liquid phase leakage and poor thermal conductivity of PCMs, particularly prominent in organic ones, have limited their practical application. In this work, we employed polyethylene glycol (PEG) with the phase change temperature of 61.72 °C as PCMs. A poly(phenol-amine) was synthesized via the Schiff base reactions or Michael-type additions using low-cost Catechol and Diethylenetriamine, and was applied to modify the surface of melamine foam (MF). The abundant polar groups and aromatic rings in the poly(phenol-amine) enable strong interactions with both MF and PEG. Additionally, MXene was incorporated to further improve the thermal conductivity of the composite phase change materials (CPCMs). The results demonstrated that the modified MF/MXene/PEG based CPCMs showed negligible leakage when tested at 80 °C for 1 h. They also exhibited an enhanced thermal conductivity of 0.55 ± 0.01 W/m·K with an enthalpy value of 186.4 J/g. Moreover, after 100th thermal cycling and reprocessing, the crystallization behavior and phase transition capability of the CPCMs remained almost unchanged. Furthermore, the introduction of MXene markedly enhanced CPCMs’ light absorption efficiency. These findings indicate that the prepared CPCMs, with their excellent thermal performance, hold substantial potential in energy storage and thermal management applications. Graphical

In this work, we proposed a novel strategy for the conversion and storage of photothermal energy. This strategy combined hydrothermally prepared CuS/rGO with commercial epoxy resin adhesives. The light-capturing capability of CuS and fast electron transfer rate of rGO was harnessed to endow the modified resin with photothermal conversion capability. Using an inorganic PCM as the energy-storage medium and melamine foam as its support carrier, a form-stabilized composite phase-change material with a latent heat of phase change of 233.7 J/g and a phase-change temperature of 48.7 °C was obtained. In addition, the pre-prepared MER was coated onto the surface of the CPCM . Its purpose was to utilize the photothermal conversion and waterproof properties of modified resins to store solar energy in the internal phase-change materials, while alleviating the leakage problem during the phase-change process of inorganic salt hydrate phase-change materials in the past. The leakage tests showed that the 1.0 mm thick MER provided excellent protection against leakage, significantly reducing leakage of the liquid phase and moisture escape. The composite phase-change material CPCM/MER demonstrated satisfactory results in photothermal conversion experiments. 2% CuS/rGO addition to CPCM/MER can complete the phase change. The samples also showed good stability in the cycling tests. After 100 cycles of testing, the latent heat of the CPCM only decreased by 5.13%. According to the FT-IR results, the CPCM also possessed chemical stability. In this study, a CPCM/MER was successfully prepared, extending the practical application of traditional inorganic phase-change materials in the field of solar energy storage.

ZIF-8 and polydopamine (PDA) double -modified melamine foam (MF), namely ZIF-8@PDA MF was fabricated using a new in-situ growth method for the co-removal of multiple organophosphorus flame retardants (OPFRs) from environmental water. The resulting ZIF-8@PDA MF exhibited a porous, three-dimensional (3D) cross-linked network in which ZIF-8 evenly distributed on MF via the PDA’s adhesive properties, leading to a 17-fold increase in surface area (from 1.357 to 22.964 m 2 /g) to facilitate mass transfer and target binding. Through experimental confirmation, the mechanisms of hydrogen bonding, π-π, electrostatic and hydrophobic adsorption enable the effective removal of 11 types of OPFRs including aryl-, alkyl- and Cl-OPFRs. Compared to the adsorbents reported previously, ZIF-8@PDA MF achieved higher removal efficiencies (53.8%–99.7%), particularly a 30% improvement for highly polar TEP and TCEP. The adsorption behavior of OPFRs by ZIF-8@PDA MF followed a spontaneous, endothermic process, conforming to the pseudo-second-order model and Langmuir model. The adsorption equilibrium could be reached within one hour, 2-48 times faster than most reported studies (2-48 h). In addition, ZIF-8@PDA MF was demonstrated to efficiently remove multiple OPFRs from raw environmental water and the reusability reached up to four cycles without requiring secondary separation, highlighting its practical applicability.

Asymmetric structural design and reduction of secondary contamination have been at the forefront of the development of electromagnetic shielding composites. Herein, the melamine foam@ferric oxide/cellulose nanofibers@carbon nanotube/polydimethylsiloxane/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (MF@Fe3O4/CNF@CNT/PDMS/PEDOT:PSS) (MC2PP) composites with an asymmetric three-dimensional porous-planar integrated structure are prepared by a solvothermal reaction, infiltration, and coating. A PDMS-encapsulated MF@Fe3O4/CNF@CNT porous composite is designed as an absorbing layer for absorbing electromagnetic waves (EMWs). The conductive polymer PEDOT:PSS, coated on the upper surface of the MF@Fe3O4/CNF@CNT/PDMS composite, is designed as a reflective layer. The MC2PP-2.4 composite obtains an average SET of 38.81 dB and an absorption coefficient (A) value of 0.654 at the X-band when the EMWs are incident from the MF@Fe3O4/CNF@CNT/PDMS side (M-side, porous absorber layer). When the EMWs are incident from the PEDOT:PSS side (P-side, planar reflecting layer), the MC2PP composite obtains an average SET of 39.00 dB and a reflection coefficient (R) of 0.964. The asymmetric structural design, along with conductive losses, magnetic losses, and interface polarization, contributes to the electromagnetic shielding performance that can be absorbed on one side and reflected on the other. More importantly, the elastic melamine foam composites are simple to prepare, reliable in process, stable in performance, and a unique scalable composite material, which have a broad application prospect in the field of electromagnetic interference shielding.

The liquid leakage, low light absorption capability and strong rigidity severely limit large-scale applications of phase change materials (PCMs). In this work, novel PCM composites with good encapsulation property, superior solar-to-thermal conversion efficiency and shape memory function were fabricated by introducing MXene-coated melamine foam (MF@MXene) into poly(ethylene glycol) (PEG). The MF@MXene/PEG composites showed satisfactory dimension retention ratio (90%) and phase change enthalpy (194.1 Jg −1 ). The three-dimensional MXene network constructed along the MF skeleton imparted the PCM composites with the ability to absorb and store the solar-energy as latent heat. Sunlight irradiation measurements suggested that the solar-thermal conversion efficiency reached 92.7%. Moreover, combining the resilience of MF@MXene sponge and the phase transition of PEG, the PCM composites exhibited remarkable shape fixation and recovery effects. A flexible heat eye-patch was further developed, which could be closely attached on human eyes and provided long-time thermal comfort within a stable temperature range.

Realizing high-efficiency thermal conductivity enhancement at low filler loading has a great significance for thermally conductive composite. Herein, three-dimensional (3D) boron nitride nanosheets (BNNSs) wrapped melamine foams (MF@BNNS) were first fabricated by repeated layer-by-layer (L-B-L) assembly using melamine skeleton as substrate and BNNSs as building blocks. The resultant MF@BNNS scaffold with order and interconnected BNNS layer, as a thermally conductive network, was further infiltrated with epoxy resin. As a consequence, a relatively high thermal conductivity of 0.6 W m −1 K −1 was achieved at an ultralow BNNS loading of ∼1.1 vol%, which is equivalent to a thermal conductivity enhancement of 233% compared to epoxy resin. Besides, the obtained epoxy composite also possesses a good mechanical property and excellent electrical insulativity. This method can be further extended to construct 3D filler network of other 2D layered materials on the melamine foam for high-performance composite.

Form-stable phase change materials (PCMs) are widely used for thermal management. However, the strong rigidity and the weak photoabsorption ability have hindered their practical applications. Herein, we report a flexible PCM based on paraffin wax (PW) and polydopamine-coated melamine foam (MF@PDA) for the seamlessly combined light-actuated shape memory and light-to-thermal energy storage capability. The MF@PDA foams with different PDA contents, which act as supporting scaffolds to adsorb PW, are successfully obtained by varying the immersion times and the dopamine concentrations. The low density and high porosity of MF@PDA foams allow for high weight fraction of PW to be incorporated, making the PCMs show high latent heat and encapsulation ability. Simultaneously, the elastic MF@PDA foams impart the PCMs with good shape memory property by triggering the phase transition of PW. More importantly, due to the efficient photothermal effect of PDA coating, the PCMs exhibit excellent light-actuated shape memory effect (shape recovery ratio ∼ 100%, shape recovery speed ∼ 100 s) and solar-to-thermal energy storage efficiency (80.8%). The light-actuated shape recovery rates and the solar-to-thermal transfer rates are increased with the augmented amount of PDA coating. Besides, the PCMs exhibit quite stable shape memory cyclic performance and thermal reliability. This study provides a new strategy to design flexible and light-responsive PCMs with the potential to be used in advanced solar energy storage systems.
