摘要

实验研究了电晕放电对聚甲基丙烯酸甲酯(PMMA)和苯乙烯丙烯腈(SAN)绝缘固体疏水性的影响。对沉积在电晕老化样品上的水进行接触角评价，可以表征表面条件的演变。并计算了电应力作用下黏附能随时间的变化。我们观察到，接触角和粘附能取决于表面的物理化学特性和施加的电应力持续时间。利用傅里叶变换红外光谱(FTIR)分析了这些绝缘体的降解状态。

Effect of Aging Time on the Hydrophobicity of Polymers Subjected to Corona Discharge

An experimental study on corona discharge effect on hydrophobicity of Polymethyl methacylate (PMMA) and Styrene acrylonitrile (SAN) insulating solids is presented here. Contact angle evaluation of water deposited on the corona aged sample allows evolution of the surface condition to be characterized. More, time variation of adhesion energy, under electrical stress is calculated. We observe that contact angle and adhesion energy depend on of the surface’sphysico-chemical characteristics, and onapplied electrical stress duration.. State of degradation of these insulators is analysed usingFourier transform infrared spectrometry (FTIR).
