Innovation in Material Science: the Chameleon Block Copolymer
This note to the editor is the first journal publication of the chameleon thermoplastic elastomer with entropy-driven phase separation. We have discovered that block copolymers with a high-molecular-weight, dendritic (arborescent) polyisobutylene core and poly(para-methylstyrene) end blocks can manifest themselves either as rubber or as plastic, depending on their environment. The behavior is thermally irreversible. This material represents a new concept in material science: the entropy-driven thermoplastic elastomer.
