In my talk, I will present a new macromonomer design concept for the synthesis of mechacnially tough self-heailng network. Our macromonomer can spontaneosly assemble into well-ordered 1d nanostructures and form highly entangled dynamic network. Suhc unique network structure result in highly stretchability, high fracture toughness and even autonomous self-healability. In addition, we stabilize dynamic network by post-photopolymerization method and impart excellent elasticity. I am going to discuss more details for design concept of our new macromonomer and their mechacnial properties.
