摘要

为了提高聚丙烯电池隔膜亲水性

用大气压氦气/空气介质阻挡放电（DBD）等离子体对其表面改性。用示波器测量了DBD的伏安特性

通过蒸馏水的接触角测量、X射线光电子能谱（XPS）分析、扫描电子显微镜（SEM）观察等手段对大气压氦气/空气DBD等离子体处理前后聚丙烯隔膜表面性质进行表征

同时分析样品亲水性的时效性。实验结果表明

大气压DBD等离子体处理过后聚丙烯隔膜表面引入了含氧极性基团（如C-OH

C=O

HO-C=O等）

使表面蒸馏水的接触角显著下降

样品表面亲水性显著提高。

Abstract

In order to improve the hydrophilicity of polypropylene（PP）battery membrane

atmospheric pressure helium/air dielectric barrier discharge（DBD）was used to modify the characteristics of PP membrane surface.Voltage-current waveform was measured by oscillograph.The properties and microstructures of the PP membrane were characterized with water contact angle measurement

X-Ray Photoelectron Spectroscopy（XPS）and scanning electron microscopy（SEM）.Besides

aging effect was studied.The PP mem brane

modified with the atmospheric pressure helium/air DBD

showed a significant decrease in water contact angle due to the incorporation of oxygen-containing groups

such as C-OH

C=O

HO-C=O et al.
