采用电子束（EB）引发接枝技术和化学磺化处理制备了聚全氟乙丙烯（FEP）功能化材料。将功能化的FEP（s-FEP）薄膜在常温下浸泡在硝酸银（AgNO 3）溶液中，进行离子交换，得到Ag+离子型s-FEP聚合物。用30 keV的Ga+聚焦离子束（FIB）和6 MeV/u的Ne 10 +/sup>分散离子束（DIB）辐照Ag形成的s-FEP。通过扫描电子显微镜（SEM）和能量色散X射线光谱（EDX）对辐照区域进行评价。在FIB和DIB照射的两种情况下，纳米尺度的颗粒出现在照射区域的表面上。从颗粒的EDX分析结果，归属于银原子的峰被清楚地检测到，并且峰强度高于未照射的峰。结果表明，AgM+离子在离子束辐照下被还原，形成纯银金属及其氧化物的银纳米颗粒。
Functionalized poly(tetrafluoroethylene-co-hexafluoropropylene (FEP) ) was fabricated by electron beam (EB) induced grafting technique and chemical sulfonation treatment. The functionalized FEP (s-FEP) films were immersed in the silver nitrate (AgNO3) solution under ambient condition, to exchange on ionic sites from proton ion-form to Ag+ ion-form, and then the Ag-formed s-FEP polymers were obtained. Ag-formed s-FEP was irradiated with 30 keV Ga+ focused ion beam (FIB) and 6 MeV/u dispersed Ne10+>/sup> ion beam (DIB). The irradiated areas were evaluated by a scanning electron microscopy (SEM) with an energy dispersive X-ray spectroscopy (EDX). In both cases of FIB and DIB irradiations, the nano-scale particles were appeared on the surface of irradiated areas. From the results of EDX analysis for the particles, the peaks which were assigned to silver atoms were clearly detected, and peak intensities were higher than un-irradiated one. It is suggested that the AgM+ ions would be reduced by ion beam irradiation and appeared as silver nano-scale particles with pure silver metal and its oxidative chemical compounds.
