摘要
Abstract
This experiment addresses the challenge of understanding the abstract concept of"living"in living radical polymerization within the undergraduate teaching of polymer chemistry course.We conducted a 3D printing experiment using photo-induced reversible addition-fragmentation chain transfer(RAFT)polymerization.Initially,we synthesized O-(ethyl)-S-(2-propyl ethanoate thio)xanthate(EXEP)under optimized conditions.Subsequently,3D printing was performed with commercial photosensitive resin under conditions with and without EXEP.The printed structures were then subjected to post-modification with a fluorescent monomer,and a comparative experiment on polymer welding was conducted.By analyzing and comparing the experimental results,we aimed to visually demonstrate the mechanism of living radical polymerization and its impact on post-functionalization.This experiment seamlessly integrates foundational theory into an engaging practical context.It is characterized by its reasonable duration,simplicity in operation,significant outcomes,and alignment with basic requirements for undergraduate teaching experiments.Furthermore,it contributes to enhancing students'comprehensive analytical abilities,sparking their interest in deeper research,and cultivating their innovative awareness and extension capabilities.关键词
