摘要
采用萘-钠化学处理和低温射频等离子体处理方法处理聚四氟乙烯(PTFE)。利用傅立叶红外光谱仪、静态接触角测量仪、绝缘电阻测试仪和扫描电子显微镜对改性效果进行了研究。结果表明,采用萘-钠化学处理,接触角可以降低至20°,剪切强度可以增大至3.564 MPa,表面电阻率会降低至182.6 GΩ;采用低温射频等离子体处理,接触角下降到72°,剪切强度增大到1.925 MPa,表面电阻率下降到190.4 GΩ。
Polytetrafluoroethene were treated with sodium naphthalene soultion and low temperature radio-frequency plasmas. The modification effects were evaluated by FTIR spectra, static contact angle measurment, insulative-resistanee conner and scanning electron microscope. The results showed that when sodium naphthalene souhion was used, contact angle reduced to 20°, lap shear strength increased to 3. 564 MPa and surface resistivity reduced to 182.6 GΩ; when low temperature radio-frequency plamas method was employed, contact angle fell to 72°, lap shear strength increased to 1. 925 MPa, and surface resistivity dropped down to 190.4 GΩ.
