Frontal polymerization (FP) is an approach for thermosetting plastics at a lower energy cost than autoclave. The potential to generate simultaneous propagation of multiple fronts has been discussed as exciting possibility. However, FP initiated more two points simultaneously not demonstrated. Multipoint initiation could enable both large-scale material fabrication and unique pattern generation. Here, the authors present laser-patterned photothermal heating method locations in 2-D sample....
Abstract Frontal polymerization provides a rapid, economic, and environmentally friendly methodology to manufacture thermoset polymers composites. Despite its efficiency reduced environmental impact, the manufacturing method is underutilized due limited fundamental understanding of dynamic control. This work reports control patterning front propagation in dicyclopentadiene resin by immersion phase‐changing polycaprolactone particles. Predictive designed enabled multiphysical numerical...
Recently presented as a rapid and eco-friendly manufacturing method for thermoset polymers composites, frontal polymerization (FP) experiences thermo-chemical instabilities under certain conditions, leading to visible patterns spatially dependent material properties. Through numerical analyses experiments, we demonstrate how the front velocity, temperature, instability in of cyclooctadiene are affected by presence poly(caprolactone) microparticles homogeneously mixed with resin. The phase...
Amphoteric polysoaps have been prepared via statistical RAFT copolymerization using either methacryloyl sulfacetamide (mSAC) or sulfmethazine (mSMZ) and 4-hexylphenyl methylacrylamide (4HPhMA). These copolymers form pH- CO2-responsive polymeric micelles capable of sequestering hydrophobic molecules in water. The composition structure the respective can be changed to tailor onset extent CO2-dependent phase behavior. When CO2 is introduced into system, resulting carbonic acid formation, pH...
