A series of blended membranes with various fullerene ethanolamine derivative contents were prepared using the natural polymer chitosan as membrane material by casting method.The results show that these blended membranes have unique ultraviolet optical property. The light transmission spectra continuously red-shift with increasing fullerene derivative contents and the cut-off wavelength shifts from 200 nm to about 400 nm. Formation of charge transfer composites may be responsible for the unusual tunable UV light-filtering property. And the introduce of Cu（Ⅱ） can improve the optical property. 紫外滤光 富勒烯衍生物 壳聚糖 共混膜 UV optical property fullerene derivative chitosan blended membrane O631 国家自然科学基金（20304009）;湖北省自然科学基金资助项目（203130507） 2003-06-01 2021-04-01 6
