摘要: Abstract The versatility of well-defined methacrylate random copolymer having reactive maleimide pendants (CoPMA) toward robust thermoreversibility and self-healability is reported. CoPMA synthesized by a controlled radical polymerization, thus being capable for the control pendant density chain length (i.e. molecular weight). proved to be an effective polymeric dienophile yielding thermally-labile networks at room temperature with newly-synthesized polyfurans: small-molecule difunctional furan (DFu) (CoPFuMA). fabricated are dynamic elevated temperatures through retro-Diels/Alder (rDA)/DA reaction, leading rapid self-healing micron-sized cuts on CoPMA/DFu films, compared CoPMA/CoPFuMA films.
