Abstract
Recently, polymer surface modification has been conducted to enhance function and properties. In this study, the effect of electron beam irradiation on surface properties, such as wettability, chemical bonding state, surface roughness, hardness, critical load, and friction coefficient, of polymer coating was investigated. The polymer coating was bombarded with an intense electron beam under incident energies of 300, 600, and 900 eV for 5 min. The electron beam irradiation results showed that the contact angle was reduced as the surface converted to hydrophilic due to the formation of the carboxyl (-COOH) group. In addition, surface hardness and critical load was improved by increasing the crosslink in the polymer by electron beam irradiation.
