摘要

Main observation and conclusion Polymerization-induced self-assembly (PISA) is an effective method to prepare block copolymer (BCP) particles with various mor-phologies.However,BCPs with inverse bicontinuous phase structure have been rarely prepared via PISA.Herein,we report the prep-aration of particles,consisting of poly(N,N-dimethylacrylamide-b-poly(4-tert-butoxystyrene-co-pentafluorostyrene) BCP,with inverse bicontinuous phases via PISA in ethanol/water.The effects of solvent composition and the degree of polymerization of the core-forming were investigated.The bicontinuous structure of BCP particles was characterized by transmission electron microscopy.
