摘要
通过微波辅助溶剂热原位合成反应,制备了CdS负载量更高的氧化细菌纤维素(TOBC)@硫化镉(CdS)纳米复合凝胶材料.FT-IR、SEM、EDS、XRD和Raman结果表明,在羧基的络合作用下,立方晶型CdS纳米团簇以类似细胞感受器的形貌主要吸附在TOBC纤维非结晶区域,形成了较为稳定的有机无机杂化结构.这为高效、简洁制备纳米复合纤维素凝胶提供了良好的思路.
Oxidized bacterial cellulose(TOBC)@cadmium sulphide(CdS)nanocomposite gel with high CdS loading percentage was obtained through microwave-assisted solvothermal in-situ synthesis reaction.The results of FT-IR,SEM,EDS,XRD and Raman revealed that cell receptor-like cubic CdS nanoclusters were mainly attached to amorphous region of TOBC fiber via complexation of carboxyl group,which forming stable organic-inorganic hybrid structure.The high-efficient and sample method provides new ideas to prepare nanocomposite cellulose gel.
