采用表面引发原子转移自由基聚合法合成偶氮苯聚合物刷

The synthesis of AZO-polymer brush via surface-initiated atom transfer radical polymerization

通过重氮偶合法合成带有光学活性官能团的偶氮苯化合物,采用表面引发原子转移自由基聚合法在金膜基体表面制备光学活性偶氮苯聚合物刷.用傅立叶红外转换光谱、原子力显微镜、紫外-可见吸收光谱等测试手段对聚合物进行性能表征,结果表明:偶氮苯聚合物可成功地接枝在金膜表面.

A serial of azobenzene compounds with reactive functional groups were synthesized by diazo-coupling.Photo-sensitivity azobenzene-containing polymer brush was fabricated on gold substrate by the method of surface-initiated atom transfer radical polymerization（ATRP）.The polymer has been characterized by means of fourier transform infrared spectrum,atom force microscopy and ultraviolet visible spectrum.It showed that the azobenzence polyemer was successfully grafted onto the gold film surface.
