Investigation of Thermo-chemo-mechanically Coupled Phenomena in Frontal Polymerization
Frontal polymerization is a proven energy-saving and rapid method of synthesizing polymers with good mechanical properties. With a small energy input, a reaction front propagates rapidly through the sample, transforming monomer (liquid or soft gel) into polymer (stiff solid), and is self-sustained …
