A facile method to decorate the polymeric hollow spheres with ZnS nanoparticles has been presented. In this method, the precursors, Zn(Ac)(2)H(2)O and CH(3)CSNH(2), were first adsorbed by the polymer substrate in supercritical CO(2)-ethanol solution at 35 degrees C. Followed by heating the mixture at 100 degrees C for 2 h, ZnS/polymer composites were obtained. The as-produced ZnS/polymer composites were characterized by means of IR spectra, X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy. It was demonstrated that crystalline ZnS nanoparticles with size of 3-5 nm were uniformly decorated on the polymer spheres under suitable conditions. The resultant ZnS/polymer composites exhibited high efficiency for degrading eosin B, methyl orange and methylene blue under UV light irradiation.
提出了一种用硫化锌纳米颗粒修饰聚合物空心球的简便方法。在该方法中，前驱体醋酸锌二水合物（Zn(Ac)(2)H(2)O）和硫代乙酰胺（CH(3)CSNH(2)）首先在35℃的超临界二氧化碳-乙醇溶液中被聚合物基质吸附。随后将混合物在100℃加热2小时，得到硫化锌/聚合物复合材料。通过红外光谱、X射线衍射、透射电子显微镜、高分辨率透射电子显微镜对所制备的硫化锌/聚合物复合材料进行了表征。结果表明，在合适的条件下，尺寸为3-5纳米的结晶硫化锌纳米颗粒均匀地修饰在聚合物球上。所得的硫化锌/聚合物复合材料在紫外光照射下对降解曙红B、甲基橙和亚甲基蓝表现出高效率。
