Chinese Abstract

本研究以聚酯不織布為基材,利用射頻(RF)電漿對纖維進行表面活化處理,並將丙烯酸的單體,以接枝共聚合方式使其表面產生大量羧酸基團,接著再利用化學法將幾丁聚糖接枝於羧酸基上進行第二段表面改質。經表面處理改質後之聚酯不織布以衰減式全反射(ATR-FTIR)傅立葉紅外光譜儀進行表面分析,並進行親水性與抗茵性試驗。實驗結果顯示,聚酯不織布藉由電漿處理進行丙烯酸之接枝後,纖維表面產生羧酸基團,故其親水性明顯增加。而聚酯不織布基材鍵結幾丁聚糖後,其表面對於金黃色葡萄球茵及大腸桿茵均具有良好的抗茵效果。

English Abstract

In this study, polyethylene terephthalate (PET) non-woven was pretreated using radio frequency (RF) plasma to improve surface activation, followed by grafting with acrylic acid (AAc) monomer and generating Q=C-Q group at surface. The pAAc-grafted PET was then covalently bonded with chitosan to be used as an anti-bacterial fabric surface. Modified and unmodified fabrics were characterized using Fourier-transformed infrared spectroscopy with attenuated total reflection (FTIR-ATR). Experimental result indicated that plasma-treated Aac-grafted property PET created polarizable O=C-O group, which demonstrated a hydrophilic; subsequent bonded with chitosan, the fabric surfaces provided a significant anti-bacterial (Escherichia coli and Staphylococcus aureus) effect.
