摘要

近年來常使用低溫電漿來改質高分子材料的表面性質，由於低溫電漿處理的能量常常會導致材料機械性質的下降。本研究中探討使用低溫電漿處理高強力聚乙烯織物前後機械強度的改變以及對織物親水性的影響。研究中發現，高強力聚乙烯織物經過氧氣電漿處理過後，對其親水性質有明顯的改善；然而，高強力聚乙烯織物的纖維強度卻會隨著不同電漿處理的時間以及處理的功率而下降。本研究中使用了傅利葉紅外線光譜來分析電漿處理過後高強力聚乙烯織物表面官能基的變化，也藉由掃描式電子顯微鏡觀察纖維表面受電漿蝕刻的情形。

In recently years, low temperature plasma treatment is used to modify the surface property of polymer, but energy of plasma treatment will due to the reduction of the mechanical properties of polymer. In this work, polyethylene fabrics which are composed of high tenacity fibers of polyethylene was treated with low temperature plasma, and also discussed that the wettability and tenacity of polyethylene fibers after treatment. We found that the wettability of polyethylene fabrics were improved and could absorb water after treatment by low temperature plasma、but the tenacity of polyethylene fiber was decreased with increasing treatment time and radio frequency power, respectively. Moreover, we also measured the deposited chemical groups on the surface of polyethylene fabrics by FTIR and also observed the surface of high tenacity fibers by scanning electron microscopy.
