利用低温等离子体,以氩气为工作气体,在工作压强为20Pa、处理功率为30w的条件下对HDPE薄膜进行了表面改性。用接触角、SEM、AFM、XPS等手段对改性结果进行了分析和表征。研究结果表明:在0~300s的处理时间内,失重率在处理时间为90s左右时达最大值;接触角在0~160s内随处理时间的增加显著减小,而在160~300s的处理时间内没有发生明显变化;改性后的接触角随着放置时间的推移出现微弱回复;HDPE薄膜经过氩气低温等离子体处理后,能在其表面形成各种极性基团,主要是羰基、羟基和羧基,且薄膜经处理后,其表面的结合能及平面光洁度发生了改变。
利用低溫等離子體,以氬氣為工作氣體,在工作壓彊為20Pa、處理功率為30w的條件下對HDPE薄膜進行瞭錶麵改性。用接觸角、SEM、AFM、XPS等手段對改性結果進行瞭分析和錶徵。研究結果錶明:在0~300s的處理時間內,失重率在處理時間為90s左右時達最大值;接觸角在0~160s內隨處理時間的增加顯著減小,而在160~300s的處理時間內沒有髮生明顯變化;改性後的接觸角隨著放置時間的推移齣現微弱迴複;HDPE薄膜經過氬氣低溫等離子體處理後,能在其錶麵形成各種極性基糰,主要是羰基、羥基和羧基,且薄膜經處理後,其錶麵的結閤能及平麵光潔度髮生瞭改變。

The surface of high density polyethylene was modified using low temperature Ar plasma technology under the condition of vacuum pressure of 20 Pa and treatment power of 30 W. The results have been analyzed and characterized with water contact angle measurement, scanned electron microscopy(SEM), atomic force microscopy(AFM), XPS, etc. The results show that the weight loss rate of per unit area has reached maximum value at discharge time of 90 seconds during the treatment time of 0 -300 s; the water contact angle sharply decreased in the 0 - 160 s treatment time and their values did not cause significant changes during the 160 -300 s treatment time; the water contact angle gradually increased with the longer standing time; the surface of HDPE could form some polar species such as carbonyl, hydroxyl and carboxyl groups and the binding energy of the surface changed after treatment by low temperature Ar plasma.
