Abstract.The effect of electron beam (EB) irradiation on polytetrauoroethylene (PTFE) film has been studied in air at room temperature. Changes in the chemical structure were determined by Fourier transform infrared (FTIR). Morphological changes on the film surface were described using field emitting scanning electron microscopy (SEM). The surface hydrophilicity of the modified film was characterized through water contact angle measurement. The scission of the chain in the surface of PTFE film was induced by electron irradiation. The atomic ration (F/C) was decreased and the atomic ration (O/C) was increased. Surface roughness of the sample irradiated increased. In case of irradiation in presence of residual air carboxylic acid fuoride groups are incorporated which can hydrolyze to carboxylic groups in the surface-near regions. These polar groups reduce the hydrophobic and oleophobic properties so much that the water contact angle of the film surface reduced significantly. Keywords: Polytetrafluoroethylene; Electron beam irradiation; modification; wetting property |
