Wastewater treatment contributes to the sustainable utilization of water resources for alleviating water scarcity. The application of polymeric materials as adsorbents for eliminating hazardous substances in water has garnered extensive attention owing to their remarkable adsorption efficiency, stability, and selectivity. Herein, a facile strategy is provided to rapidly synthesize poly(acrylic acid- co -sodium 2-acrylamide-2-methylpropanesulfonate) (poly(AA- co -NaAMPS)) hydrogels with exceptional adsorptive capacity via frontal polymerization (FP). The FP processes are meticulously examined in terms of initiator dosage and monomer ratio. The as-prepared hydrogels demonstrate pH-responsive swelling ability and pH-dependent adsorption capacity for various dyes and heavy metal ions. Compared with traditional batch polymerization (BP), the hydrogels prepared by FP exhibit superior swelling and adsorption abilities. Additionally, research on the adsorption mechanism for both dyes and heavy metal ions is conducted by fitting the adsorption kinetic data both with Langmuir and Freundlich equations. The maximum adsorption capacity ( q m ) of hydrogels derived from Langmuir model for dyes of methylene blue (MB) and rhodamine B (RB) is, respectively, 595.3 and 3078.5 mg g −1 , while for heavy metal ions of Cr 3+ and Cd 2+ is, respectively, 1010.8 and 1191.3 mg g −1 . This research exploits an alternative approach for the rapid preparation of high-efficiency hydrogel adsorbents toward wastewater treatment. Graphical Poly(AA- co -NaAMPS) hydrogels are facile synthesized through frontal polymerization within 10 min. The as-prepared hydrogels display excellent adsorption ability for both dyes and heavy metal ions. The maximum adsorption capacity for dyes of methylene blue and rhodamine B is, respectively, 595.3 and 3078.5 mg g −1 , while for heavy metal ions of Cr 3+ and Cd 2+ is, respectively, 1010.8 and 1191.3 mg g −1 .

The hydrogel artificial muscle has demonstrated enormous potential in various applications, such as soft robotics and actuators. However, the poor mechanical properties have always limited the practical applications of hydrogels. Here, we designed a Zr4+ coordinated and vinyl hybrid silica nanoparticle (VSNP) grafted poly(acrylamide-co-2-acrylamido-2-methyl-1-propanesulfonic acid) (VSNP@poly(AM-co-AMPS)-Zr4+) via frontal polymerization (FP). Benefiting from the synergistic effect of the polymer–nanocomposite interaction (VSNP nanocomposite) and metal ion–ligand interactions (Zr4+–sulfonate group coordination), the mechanical properties of hydrogels can be extremely improved. In addition, a deformable hydrogel with gradient structure and swelling ratio was designed through introducing Zr4+ to one side of the hydrogel, which can serve as an artificial muscle to accomplish multiple moving activities, such as bending and grabbing. This work offers an easy-to-perform strategy to construct mechanically strong hydrogels, which might promote the development of artificial muscle materials.

Frontal polymerization (FP) offers an efficient and energy-saving alternative to conventional curing methods for epoxy resins. In this study, a transient thermo-chemical coupled heat-transfer model (V-model) was developed using temperature-dependent thermophysical properties. Curing kinetics parameters were first determined by fitting data from non-isothermal differential scanning calorimetry of a BADGE-based resin. Compared to a constant-property model, accounting for changes in thermal conductivity and specific heat capacity significantly improved the accuracy of the predicted temperature profiles, aligning more closely with experimental observations. The validated V-model was then extended to evaluate the impact of boundary materials with different thermal conductivities on FP behavior. Experiments confirmed that high-conductivity boundaries facilitate preheating of unreacted resin, thereby promoting faster polymerization-wave propagation. Meanwhile, insulating boundary materials minimize heat loss, sustaining the FP reaction. This combined computational–experimental approach provides deeper insights into the heat-transfer mechanisms governing epoxy resin FP and guidance for optimizing industrial process parameters.

This work advances ultrasound-initiated frontal ring-opening metathesis polymerization (U-FROMP) as a two-mode curing platform that uses acoustic cavitation to activate the catalyst and initiate self-propagating fronts. Building on Direct U-FROMP in neat dicyclopentadiene (DCPD), we establish Remote U-FROMP, a fully non-contact configuration in which ultrasonic waves pass through water or air to produce cavitation. After optimizing both modes, we demonstrate two applications. First, Remote U-FROMP yields homogeneous p-DCPD/MMA blends at MMA up to 50 wt%, overcoming boiling-induced front quenching and phase separation that limit thermal FROMP, and suppresses fingering instabilities while supporting three-dimensional spherical front propagation, expanding frontal polymerization to previously inaccessible monomers. Second, optimized Direct and Remote U-FROMP cure carbon-fiber-reinforced polymers (CFRPs) within minutes, requiring over four orders of magnitude less external energy than oven processing. Resulting CFRPs show 15–50% higher tensile modulus, 25–30% higher flexural strength, and superior impact resistance, including penetration-resistant performance at 60 J, versus oven-cured counterparts. U-FROMP reduced void content while raising tensile and flexural moduli by 67% and 37% compared with Th-FROMP, despite a 7.1% drop in tensile strength. Ultrasound thus emerges as a distinct frontal polymerization trigger, offering clear advantages over oven-cured and thermally initiated systems.

Deep eutectic solvent (DES) was prepared by using acrylic acid (AA) and acrylamide (AM) as hydrogen bonding donors (HBD) and choline chloride (ChCl) as hydrogen bonding receptors (HBA). Nitrogen-doped carbon nanotubes (N-CNTs) were dispersed in DES as fillers, and N-CNTs/P(AA-co-AM) composite hydrogels were prepared by FP. The interaction mode between the hydrogel and N-CNTs was characterized by Fourier infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The mechanical properties, pH response and electrical conductivity of the composite hydrogels were studied. The results showed that the mechanical properties of the hydrogel were significantly enhanced with the increase of N-CNT content. The tensile strength and compressive strength of the FP4 composite hydrogel reached 5.42 MPa and 4.29 MPa, respectively. Due to the dissociation of carboxyl groups in AA in an alkaline environment the composite hydrogel showed excellent pH response performance. The conductivity of the hydrogel was also found to be improved with the content of N-CNTs. When the content of N-CNTs is 1.0 wt%, the conductivity of the hydrogel was 4.2 times higher than that of the hydrogel without N-CNTs, and connecting it to a circuit can make an LED lamp emit bright light. In this study, a simple and green method was proposed to prepare composite hydrogels with excellent mechanical properties and electrical conductivity by FP of DES in less than 5 min.

Choline chloride, acrylamide (AM) and acrylic acid (AA) were used as raw materials to prepare deep eutectic solvent, and β-cyclodextrin (β-CD) was used as filler to prepare β-CD/P(AM- co -AA) composite hydrogel by frontal polymerization. The composite hydrogel was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The pH response, mechanical properties and self-healing of the hydrogel were studied. The results show that AA contains easily ionized –COOH, which makes the composite hydrogel have excellent pH response and super-high swelling ratio under alkaline conditions. With the addition of β-CD, due to the increase of hydrogen bonds and the combination of β-CD and polymer chains the mechanical properties of the hydrogel are obviously improved and the tensile strength and compressive strength are increased by 4.12 and 2.26 times respectively. The introduction of β-CD can improve the self-healing performance of the composite hydrogel. With the increase of β-CD content, the healing rate and healing speed of the composite hydrogel show an upward trend. In this study, a simpler and faster method is proposed to prepare self-healing composite hydrogel with excellent mechanical properties and pH responsiveness. The self-healing property and the existence of a hydrophobic cavity of β-CD make β-CD/P(AM- co -AA) composite hydrogel have potential application in wound healing. © 2023 Society of Industrial Chemistry.

The development of elastomers from renewable raw material resources, with excellent properties, has been a major and difficult area of research. In this work, ternary polymerizable deep eutectic monomers (DEMs) were synthesized from acrylamide, choline chloride, and glycerol (Gy). A series of mixed hydrogels were prepared in 15 min through thermal initiation in DEM using a frontal chemical change. The eutectic gel exhibited good mechanical and self-healing properties, and the mechanical and self-healing properties of the target gel could be regulated by adjusting the proportion of Gy, while the eutectic gel could maintain high elongation and self-healing efficiency at low temperatures. Additional, eutectic gels could be compressed to a strain of more than 80% and could immediately recover to their original state when the compression force was released. In the cyclic compression test, the eutectic gel cyclic compression curves showed a high degree of overlap, and no significant hysteresis was observed, even at a set strain of 80% and 100 cyclic compression times. In addition, the eutectic gel showed fine ionic conductivity, and both the water content and Gy content could affect its conductivity, giving it the potential to be used in the application of manufacturing pressure-sensitive sensors.
