【 摘 要 】

Rotaxane cross-linked polymers (RCPs) derived from ionic liquid monomer (ILm) and butyl acrylate were prepared through radical copolymerization in the presence of a vinyl-based rotaxane crosslinker. The developed RCPs exhibited superior mechanical properties compared to analogous network polymers prepared with conventional covalent crosslinkers. In addition, a small amount of ILm toughened the formed RCPs and increased their toughness. Moreover, the developed RCPs showed ionic conductivity in the order of 10(-7) S cm(-1) at 25 degrees C.
