摘要

A novel amphiphilic copolymer poly(ethylene glycol)-block-poly(N,N- dimethylamino-2-ethylmethacrylate)-blockpoly[6-(4-methoxy-azobenzene-4′- oxy) hexyl methacrylate] (PEG-b-PDMAEMA-b-PMMAzo) was prepared by ATRP polymerization. The self-assembly and responsive behaviors were investigated by SEM, TEM, LLS and UV-Vis spectra. The results indicated that the copolymers can self-assemble into spherical structures in aqueous media. The aggregate size can be tuned by pH and temperature. The trans-cis isomerization behavior of the formed aggregates was also examined. Upon irradiation with a linear polarized light, the elongation degree of the aggregates was increased with the irradiation time.
