摘　　要：利用氧气低温等离子体,在工作压力为20Pa、功率为30W的条件下对HDPE薄膜进行表面改性。采用接触角、FT-IR-ATR、AFM、DSC等现代分析手段对改性结果进行了分析和表征。结果表明,单位面积的失重率随处理时间的延长逐渐增大;接触角随处理时间的延长呈逐渐减小的趋势;处理HDPE薄膜能在其表面形成各种极性基团,主要是羰基和羧基;处理后薄膜的热性能(熔点和结晶度)发生一定改变。The surface of high density polyethylene（HDPE） film was modified using low temperature O2 plasma under the condition of working pressure of 20Pa and applied power of 30W. The modified film was studied with contact angle measurement, Fourier transformed infrared spectroscopy （FT-IR）, atomic force microscopy （AFM）, differential scanning calorimetry（DSC）, etc. The results show that the mass loss rate of per unit area is improved, but the contact angle is gradually decreased with the increase of the treatment time; the treated surface of HDPE can form some polar species such as earbonyl and carboxyl and the melting peak temperature and crystallinity of the film are changed after treatment by low temperature O2 plasma.
