In this study, we adjusted electron density of furan pendant groups of furan-functionalized copolymers to investigate difference of self-healing efficiencies via thermal reversible Diels-Alder(DA) reaction. Two types of furan functionalized polymethacrylates(poly(furoyl ethyl ether methacrylate)(FEEMA64) and poly(furfuryl 2-(methacryloyl)ethyl carbamate)(FMAECM64)) that have difference in electron density were prepared via free-radical polymerization. Then, 1,1’-(methylenedi-4,1-phenylene)bismaleimide(bM) was used as the cross-linker for making cross-linked film by thermally reversible Diels-Alder reaction. The self-healing property and efficiencies were measured using prepared films. Detailed results of polymer properties and healing performance were characterized by various measurements. |
