摘　　要：基于聚二甲基硅氧烷(PDMS)可成膜的特殊性质,提出了以纳米金为金种,PDMS为基体制备出纳米金-PDMS复合薄膜。首先用三甲基氯硅烷(TMCS)对玻璃衬底进行硅烷化处理,在衬底表面旋涂PDMS薄膜。然后分两步用化学还原法还原氯金酸溶液,制备出纳米金复合薄膜。通过扫描电镜观察纳米金复合薄膜的形貌结构,研究了复合薄膜的紫外可见光吸收曲线。并用半导体特性分析仪(B1500)对不同还原时间的纳米金复合薄膜进行了电学测试。结果表明:复合薄膜光学性质良好,薄膜中纳米金颗粒的数量可以通过调节还原时间来控制,第二步还原14h时可得到电学性能相对较好的复合薄膜。Based on the special properties of PDMS,AuNPs-PDMS composite film were presented,which composed of Au seeds with PDMS as a matrix. Firstly,the silanized glass substrate was spin-coated with PDMS. Then the nano-gold composite films were preparation by two-step reduction of PDMS membrane. The morphology of composite films was char- acterized by SEM,while the UV-visible absorption spectrum was studied. The nano-gold composite films with different re- ducing time were tested by B1500. It is shown that the composite films had a good optical properties, the number of gold nanoparticles in the film can be controlled by adjusting the reduction time. The film＇s electrical properties were better when the second reducing step was 14h.
