摘要
采用电化学沉积法制备了氧化亚铜/壳聚糖纳米复合膜材料,并探讨了沉积时间和分散剂对复合膜的表面形貌的影响,确定了CTAB的投放量为100 mg/L,沉积时间为30 min作为最优化的实验条件.研究了氧化亚铜复合前后晶体结构的变化,探讨了氧化亚铜/壳聚糖纳米复合膜对可见光的吸收性能,为壳聚糖在半导体光催化材料中的应用提供了新的思路.
The preparation and characteristics of Cu2O/CS nanocomposite film have been investigated. The results indicate that the morphology can be changed by controlling reaction time and the concentration of CTAB. By comparing the crystallogram of CS film, Cu2O nanocrystalline with the crystallogram of Cu2O/CS nanocomposite film, we can conclude that the crystal structures of Cu2O were kept in line before and after combination. The UV-Vis absorption spectrum and diffuse reflection spectrum of Cu2O/CS nanocomposite film have been studied. The findings show that Cu2O/CS nanocomposite film has the strong absorption abilities of visible light.
