通过控制硫化锌室温成核反应在油-水液-液界面处进行,并采用羟基端基自组装分子层修饰的聚合物膜作为柔性衬底,最终在衬底表面制得硫化锌纳米晶膜.X射线衍射表征显示产物为高温稳定的纤锌矿结构.扫描电镜和透射电镜观察发现硫化锌膜由粒径30~50 nm的颗粒构成.产物对甲基橙的光催化降解研究证实在紫外光辅助下硫化锌纳米晶膜对有机物的降解能力.鉴于上述结果,提出了一种结合油-水液-液界面及自组装分子层功能化的衬底,在室温且无添加剂条件下一步制备高温稳定相Zn S功能膜的方法,并分析了产物形貌与光催化性能间的关系.
By controlling the room temperature nucleation reaction of zinc sulfide at the oil-water liquid-liquid interface, a polymer film modified with hydroxyl-terminated self-assembled molecular layer was used as a flexible substrate to finally obtain a zinc sulfide nanocrystalline film on the surface of the substrate. X-ray diffraction (XRD) characterization showed that the product was wurtzite with high temperature stability. Scanning electron microscopy and transmission electron microscopy revealed that zinc sulfide film was composed of particles with particle size of 30-50 nm. Photocatalytic degradation of methyl orange by product showed that UV- Assisted by the zinc sulfide nanocrystalline film on the degradation of organic matter.According to the above results, a combination of oil - water liquid - liquid interface and self-assembled molecular layer functionalization of the substrate at room temperature and without additives, one-step preparation of high temperature The method of stabilizing the Zn S functional film was discussed. The relationship between the morphology and the photocatalytic properties was also analyzed.
