氟素橡膠(FKM)具有耐熱、耐油、耐溶劑、耐腐蝕、耐疲勞等優異性能，廣泛應用於普通橡膠無法承受的苛刻環境中，但較昂貴。然而丁腈橡膠(Nitrile rubber，NBR)具有良好的耐磨性、耐老化性和旋轉密合性，但在高溫抗油性方面則不甚佳。將FKM與NBR接著在一起，可利用FKM的優異性能及NBR的便宜，製備出耐高溫抗油、高旋轉密合性和耐疲勞性的複合材質。為了提升FKM物性，則借助於短纖維在橡膠基質中的有規取向而使FKM得到增強。
本論文第一階段將探討自行開發配方FKM、NBR之硫化行為、基本物性與耐油性能。而由於FKM及NBR兩相容性不佳，探討經由polymer blend方法改善FKM/NBR界面接著性之效果。研究中顯示在界面層FKM/NBR比例為5/5時，其界面接著效果最好。第二階段在探討PET纖維與氟素橡膠間的界面相容性，利用Nafion及Ppyrole來含浸PET纖維，來探討其含浸過的PET纖維與未含浸的纖維在相同測試條件下，測試氟素橡膠與PET纖維之界面接著。

FKM (Fluororubber) has been widely used in harsh environment due to its outstanding performance of heat-resistance, oil-resistance, solvent-resistance, corrosion-resistance and fatigue-resistance nevertheless compared with other rubbers the high-price is the only concern.NBR (Nitrilerubber) has great performance of abrasion-resistance, aging-resistance and high rotate-sealing, but lack of oil-resistance in high operating temperature.
The aim of our work is to take advantage of Fluororubber and Nitrilerubber in fabrication of the excellent performance of anti-oil, high rotate-sealing and anti-fatigue composite materials with cheap price and outstanding properties. Additionally the processing of oriented staple fibers with rubbers were reinforced the physical properties of Fluororubber.
In this study, first the vulcanization behavior, physical and anti-oil properties of Fluororubber and Nitrilerubber were discussed respectively.
Second we employed polymer-blend technique to improve the interfacial adhesion between Fluororubber and Nitrilerubber result in the best adhesion of the interface ratio of FKM/NBR = 5: 5.
Third the compatibility of Fluororubber the dipped Ppyrole and Nafion Polyethylene terephthalate were discussed for the interfacial adhesion of FKM/PET.
