“…According to diverse initiation mode and reaction mechanism, traditional frontal polymerization is classified into three categories: differential thermal frontal polymerization, photo‐ignited frontal polymerization, and isothermal frontal polymerization. In our previous works, several new methods have been designed to initiate frontal polymerization, such as plasma, CO 2 laser, and magnetic field . Among these, our group has employed the first synthesis of polymers with diverse functions via magnetically induced frontal polymerization, the investigation of this means can be further extended to highlight the synergistic effect of magnetocaloric effect and frontal polymerization.…”

A series of the self-healing gels facilely fabricated by VI (N-vinyl imidazole) and MAH-b-CD (b-cyclodextrin grafted vinyl carboxylic acid groups) via bottom-ignited frontal polymerization (BIFP) initiated by magnetocaloric effect. Once ignited the bottom phase, the heat upward propagates to generate the "front" in the upper phase. Then, no further energy is added to maintain the reaction and the whole polymerization process experiences within minutes. In this system, the dependence of frontal velocity and temperature, along with morphology, swelling capacity, mechanical property, and self-healing efficiency, on the preparation parameters is investigated. Interestingly, the gels show good swelling capacity in the organic solvent, comparatively almost no absorption in water. Moreover, the as-prepared gels exhibit excellent auto-healing properties without any external stimuli at ambient temperature. The healed sample possesses 97% recovery of its tensile strength after 8 h healing time, which relies largely on the host-guest interaction between VI and MAH-b-CD. The results demonstrate that FP can be utilized as an efficient and energy-saving method to synthesize self-healing supramolecular gels.

“…Frontal polymerization (FP) was first explored in the 1970s by Chechilo and coworkers, and its study was revitalized in the 1990s by Pojman . Since then, research on FP has expanded significantly to include cure‐on‐demand materials, synthesis of gels and gradient materials, UV initiated methacrylate and epoxide polymerizations, composite materials, and many other applications. One of the most commonly studied types of FP (and the focus of this work) is thermal free‐radical frontal polymerization of acrylic monomers.…”

Frontal polymerization of deep eutectic solvents (DESs) made with acrylic or methacrylic acid as the monomer and hydrogen bond donor was studied. Fronts with acrylic acid and choline chloride propagated more uniformly than with pure acrylic acid, so an exploration into how the DES affected frontal polymerization was performed. The hydrogen bond acceptor of the DES was replaced by several analogs to determine the effect on the DES front behavior. The analogs used were talc, DMSO, lauric acid, and stearic acid, which acted as a heat sink, inert diluent, hydrogen bonding diluent, and inert phase change material, respectively. None of the methacrylic acid-analog systems were able to sustain a front. While the acrylic acid-analog systems did sustain a front (with the exception of stearic acid), none of the fronts replicated the acrylic acid DES behavior. The acrylic acid-talc sample behaved more violently-like pure acrylic acid polymerization-than the acrylic acid DES, and the DMSO and lauric acid samples produced slower fronts than that of the acrylic acid DES. We propose that the reactivity of the acrylic acid and methacrylic acid is enhanced in the DES.

“…However, to further enhance photo-thermal capacity, incorporating fillers can not only improve hybrid polymer characteristics but also promote a stable front, providing a promising approach for the efficient synthesis of nanocomposites. Up to now, various nanoadditives have been employed to produce nanocomposites using FP, such as quantum dots (QDs), [21,22] graphene, [23] metal NPs, [24] carbon nanotubes (CNTs), [25] activated carbon, [26] carbon fiber, [27] SiO 2 NPs, [28] montmorillonite, [29] etc. However, the use of lignin (LI) fillers in the FP reaction to enhance the light absorption capacity of the target polymer has not yet been reported, which would result in improved photothermal performance beneficial for water purification.…”

Rapid population growth and water contamination have led to a shortage of freshwater, making it crucial to find sustainable methods for water purification. Solar‐powered evaporation is an eco‐friendly approach that uses solar energy to facilitate water evaporation and separate it from contaminants. Recent studies have focused on the development of solar absorber systems that incorporate photo‐thermal materials into a porous structure to enhance the efficiency of solar‐to‐thermal conversion and elevate water evaporation capacities. However, there is a lack of studies on simple and quick fabrication methods for solar absorber materials that minimize storage constraints in real‐world applications. Frontal polymerization (FP) technology is a promising solution that offers straightforward operation, minimal energy consumption, and rapid reaction for porous polymers. In this study, a decomposable and photo‐thermal composite polymer(LI/(P(DCPD‐co‐DTD))) is synthesized using FMORP, incorporating lignin fillers to improve the light absorption capacity and photothermal performance beneficial for water purification. The water evaporation rate can reach as high as 1.63 kg m−2 h−1. This composite polymer is expected to promote solar‐driven water purification in practical applications.
