纳米银/巯基化淀粉复合材料的制备与表征

Preparation and characterization of nano-silver/thiolated starch

巯基乙酸与直链淀粉发生酯化反应,制备巯基化淀粉。微波辐射法制备纳米银/巯基化淀粉的复合材料。通过红外光谱、X射线衍射仪、扫描电镜、紫外光谱对复合材料进行表征。结果表明,巯基乙酸成功改性淀粉,在不加还原剂的前提下,微波辐射制备出淀粉/纳米银核壳结构的复合材料。

This experiment with thioglycolic acid and starch esterification reaction to synthesize nano-sitver/thiolated starch composite materials by microwave radiation. The composite was characterized by FT- IR,XRD,UV-vis and SEM. The results showed that the thioglycolic acid successfully modified starch. Nano-silver/thiolated starch composite materials was successfully synthesized by microwave radiation with- out reducing agent.
