本文研究了氩离子轰击对聚四氟乙烯（PTFE）表面疏水性的改善作用。Ar离子轰击到PTFE）。Ar离子轰击PTFE薄膜的能量密度范围为3.1× 1020 ~ 18.3× 1020 ions/m2。束流密度范围为1.25至7.5 A/m2。用静滴法研究了改性材料的疏水性。轰击试样的粗糙度，形态和结构已被估计为束流密度和加速能量的函数。结果表明，Ar离子轰击使水的接触角由原来的103 °增大到170°。结果表明，在一定条件下，Ar离子轰击可以形成超疏水表面。从表面粗糙度、表面形貌和化学键合状态之间的关系出发，讨论了氩离子轰击对聚四氟乙烯疏水性的影响。
A study has been made of the improvement of the hydrophobicity of a fluorine-polymer (polytetra-fluorinethylene, PTFE) by Ar-ion bombardment. Ar-ion bombardment to PTFE) by Ar-ion bombardment. Ar-ion bombardment to PTFE sheets was carried out at the fluences ranging from 3.1×1020to 18.3×1020ions/m2. The beam current densities were ranged from 1.25 to 7.5 A/m2. The hydrophobicity of modified materials has been investigated by means of a sessile drop method of water. The roughness, morphology and structure of bombarded specimens have been estimated as a function of beam current density and acceleration energy. It was found that Ar-bombardment causes the contact angle of water to increase from the original value 103 to 170°. The results indicate that Ar-bombardment at an optional condition results in the formation of ultrahydrdophobic surfaces. The effects of Ar-bombardment to hydrophobicity of PTFE are discussed with the relationship among roughness, morphology and chemical bonding states of the surfaces.
