本研究以改善POM與PTFE的相容性，是以表面改質的方式，使鐵氟龍(PTFE)纖維表面接枝Acrylamide(AAm)，進而降低POM/PTFE複材的摩擦係數與增加耐磨耗的特性。並比較以UV光接枝方式與電漿接枝方式在摩擦係數、耐磨耗、機械性質與DMA上改善的效果。由實驗結果可知，POM的摩擦係數為0.183，在加入15wt%電漿改質鐵氟龍纖維後，摩擦係數變為0.174，但POM加入經AAm改質的鐵氟龍纖維15wt%後，最小值可達0.159。且在衝擊強度上，POM的值為4.9kg-cm/cm，在加入15wt%鐵氟龍纖維後，衝擊強度變為6.1kg-cm/cm，但POM加入經AAm改質的鐵氟龍纖維15wt%後，最大值可達9.3kg-cm/cm。由此可知以電漿接枝聚合的界面改質是可行的。本實驗中最合適的條件為以20wt%AAm接枝10分鐘， POM與AAm-g-PPTFE纖維的摻合重量百分比為85/15。

In this investigation, the AAm was grafted onto the surface of plasma treated PTFE (PPTFE) by using plasma grafting method AAm-g(plasma)-PPTFE or UV grafting method AAm-g(UV)-PPTFE for increasing the compatibility between POM and PTFE. The frictional coefficient and the Taber wear factor would be decreased as adding the AAm-g-PPTFE into POM. On the other hand, comparing the effect of plasma grafting method with UV grafting method on the frictional coefficient, Taber wear factor, mechanical properties and DMA of composites. The frictional coefficient of POM was 0.183 and the impact strength was 4.9kg-cm/cm. However, as adding 15wt%PTFE into POM, the frictional coefficient of composites was 0.174 and the impact strength was 6.1kg-cm/cm. Furthermore, as adding 15wt%AAm-g-PPTFE into POM, the frictional coefficient was down to 0.159, the impact strength was increased to 9.3kg-cm/cm. From above description, it could be known that the plasma grafting method was a useful method to modify the interface between POM and PTFE. The suitable grafting time was 10min and the grafting concentration of AAm was 20wt%. For the cost concerning, adding 15wt% AAm —g-PPTFE into POM was concerned.
