The interfacial adhesion between carbon fibers (CFs) and matrix is mainly controlled by inherent surface structures and mutual wettability. However, CFs, with superior properties, have the low of surface wettability and activity. Changing the fiber surface can enhance the quality of interface, which expands the engineering application of CFs composites. Noticeably, the most traditional procedures involve the deterioration of fiber structure by multistep manipulation to introduce active sites, toxic reagents, high energy consumption, as well as the poor interfacial interaction between the fibers and the modified materials by the coating or deposition. Herein, an environmentally friendly and mild strategy was facilely designed via firmly coating tannic acid (TA, a renewable plant-based polyphenol, the versatile adhesive) and then covalently grafted branched polyethyleneimine (PEI) onto the fiber surface. The novel grafting significantly increased fiber surface polarity, roughness and interfacial wettability without destroying surface microstructure, resulted in the sharp improvements in interlaminar shear strength (ILSS, 51.34 MPa) and interfacial shear strength (IFSS, 66.21 MPa). Impact strength and hydrothermal aging resistance of the resulting composites were also greatly increased. The hierarchical reinforcement arising from a promising and green strategy is facile to be prepared advanced polymer composites in multifunctional applications with the demand of highly interfacial properties and the usages of energy conservation.

Recycling has attracted great attention in academia, because of the economic and environmental benefits to industry. An eco-friendly strategy for recycling office waste paper (WP) was used to sustainedly separate oil–water mixtures. The hydroxyl groups of cellulose endow WP with superlipophilic and superhydrophilic properties in air and superoleophobic features under water. WP could separate various oils from oil–water mixtures, with separation efficiencies exceeding 99%. Importantly, the superhydrophilic WP could separate oil–water mixtures containing HCl, NaOH, and NaCl with separation efficiency above 98.9% for at least 30 cycles. The superoleophobicity of WP was maintained in solutions of different pH values for at least 24 h, suggesting good durability and stability. This green method is renewable, clean, cost-effective, and environmentally friendly. More importantly, the recycled office waste paper not only removes oil from oily wastewater (such as in oil spills) but also realizes the recycling of WP. This method could provide new insights into resource recycling.

The electroplating, electrolysis, and pickling industrial processes would generate numerous gas pollutes, acid mist, which could not be essentially diminished due to its synthesis mechanism and cause gaseous environmental pollution, equipment corrosion, and endanger workers’ health. In this study, a facile, practical, and energy-saving acid mist suppression system was constructed by introducing a stacking microsphere matrix as a floating porous phase on the acid solution and not causing secondary pollution. The mechanism of this green acid mist suppression strategy mainly focused on size-selective blocking of acid mist droplets by dense stacking microsphere layer and dissipation of floating kinetic energy of bubbles in the acid mist. The factors relating to the matrix's microstructure, the particle size of microspheres, the combination of the complex particles with a wide range of particle sizes, and the thickness of the matrix on the acid mist suppression were explored. It found that the matrix constituted of a medium-sized polymer sphere (1.075 ± 0.175 mm) presents a better appearance in the acid mist suppression. When the thickness of this matrix reached 15 mm, its acid mist efficiency also came up to 100%, totally blocking the acid mist. Meanwhile, complex particles with different particle sizes and PMMA porous blocks are beneficial for suppressing acid mist. Herein, this research opened up a green and effective strategy for regulating this hazardous gas pollute, acid mist.

Aluminum metal batteries (AMBs), as a next-generation green energy system, have garnered significant attention due to their inherent safety, low cost, and environmental benignity. However, non-uniform aluminum deposition and dendrite growth during cycling lead to rapid battery failure, resulting in resource waste and environmental pollution. To enhance resource utilization and achieve aluminum metal batteries with high efficiency and long cycle life, this study proposes an eco-friendly soft ZnP-H2Im glass film fabricated via a melt-quenching process as a protective layer for the aluminum anode, which minimizes the use of hazardous substances and improves process sustainability. This material combines excellent mechanical flexibility, chemical stability, and ion transport regulation (via its sub-nanochannels), enabling homogeneous AlCl4− and Al2Cl7− migration and promoting uniform aluminum nucleation and deposition. As a result, Al//Al symmetric cells based on soft ZnP-H2Im-protected Al achieve record-breaking cycle lives of more than 10 000 hours at various areal capacities and current densities, far surpassing those of unmodified systems. In addition, after coupling the soft ZnP-H2Im-protected Al with two organic cathodes, tetrachlorobenzoquinone (TCQ) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), the AMBs demonstrate high capacity, high reversibility, and high stability, with a capacity retention of 95% after 200 cycles and 80% after 220 cycles, respectively. This study not only advances interfacial engineering for AMBs but also provides a potential reference for extending this eco-friendly coordination polymer vitrification strategy to other metal anode systems, providing a transformative approach for developing high-performance secondary batteries with enhanced resource efficiency.

Recycling spent lithium-ion batteries (LIBs) in a green and economical way is vital for maintaining the sustainability of the LIB industry. However, given the low content of high-value components in olivine-type lithium iron phosphate (LFP), traditional metallurgical processes are economically unfeasible for recycling due to high chemical/energy consumption and labor-intensive procedures. This study proposes a facile electrochemistry strategy to directly regenerate the spent LFP material by an electrically driven lithiation process as a spent LFP slurry (200 g/L) rather than as electrodes. Minimal energy and chemical consumption are achieved by enabling the healing of spent LFP without destroying the original olivine-type crystal structure. The proposed method utilizes mild healing conditions (25 °C for 2 h) and LiCl solution as the only reagent in the regeneration process, significantly lowering the expenses associated with producing cathode electrodes. The electrochemical performance of the regenerated LFP have been dramatically recovered after regeneration, exhibiting a capacity of 151.5 mA h g–1 at 0.1 C and 96.6% capacity retention over 400 cycles at 1 C. This approach demonstrates a high processing capability and offers considerable economic and environmental benefits, making it an eco-friendly option and supporting the sustainable development of the LFP industry.

Traditional water medium dyeing of polyester-cotton fabrics consumes more water and energy, and causes serious environmental pollution in comparison with one-bath dyeing of single component fiber. To achieve sustainable dyeing of polyester-cotton blends, three reactive disperse dyes with s-triazine reactive group were synthesized, and supercritical CO 2 was used as solvent to conduct the waterless dyeing. The results showed that one-bath dyeing of polyester-cotton blends could be successfully realized with the synthesized dyes. Dyeing performance of the synthesized dyes was constantly improved with the extension of carbon chain on aniline. Compared with other two dyes, the optimal color strength of polyester-cotton blends was obtained with dye 3 using dimethylsulfoxide as co-solvent, and K/S values up to 6.4 were obtained at 100 °C, 20 MPa and 120 min with a dimethylsulfoxide concentration of 80 %. σ K/S values below 0.14 and washing and rubbing fastness above 4 were displayed for the colored samples. In addition, dyeing mechanism of polyester-cotton fabrics with the synthesized dyes was discussed combined with FT-IR measurement and stripping experiments.

Flexible electrical heaters have drawn significant attention in the field of wearable electronics. A large number of studies have concentrated on improving their electrothermal performance with high heating temperatures, fast temperature response, and good thermal stability. However, the strategy of elemental modification on the electrothermal properties has rarely been explored. In this paper, the electrothermal properties of the modified laser-induced graphene (LIG) fabricated by a facile two-step process are investigated for its application as flexible electrical heaters. NOMEX polyimide composite paper is proposed as a substrate to fabricate LIG via a simple laser-writing method. Doped atoms are introduced by an eco-friendly approach of laser engraving the sodium lignosulfonate coated on the substrate. The modified LIG-based heater exhibits excellent electrothermal performance. It reaches a high steady-state temperature of 160.2 °C under a low operating voltage of 5 V, mainly due to a significantly decreased electrical resistance. Moreover, the fabricated LIG-based heater shows outstanding heating stability, ensuring reliability in practical applications. This research offers a green and low-cost approach for preparing high-performance flexible electrical heaters.
