摘要: 采用紫外光接枝法将聚丙烯酰胺接枝到硅橡胶表面,利用红外光谱仪、接触角测试仪以及扫描电子显微镜等仪器对接枝后的硅橡胶进行表征及测试,从而研究反应条件对接枝效果的影响。研究结果表明当在1kw的紫外光下照射时,接枝硅橡胶距离紫外光光源的最佳距离为15cm,混合溶剂丙酮/水的最佳体积比为6:4,光引发剂最佳用量为0.3 %。

Abstract: The surface of silicone rubber was modified via the grafting of polyacrylamide ( PAAM) by Ultraviolet, The surface composition and morphology of the modified silicone rubber were characterized by Fourier transform infrared spectroscopy (FT-IR) , contact angle measurement and scanning electron microscopy (SEM). The results showed that under 1kw Ultraviolet, the optimum distance between the silicone rubber and UV was 15cm, the optimum volume ratio of C3H3O/H2O was 6:4 and the optimum photoinitiator content was 0.3%.
