Аннотация: We studied the influence of electret charge on the hydrophilicity of polytetrafluoroethylene (PTFE)films treated by direct-current (DC) glow discharge. DC discharge treatment of polymers leads to significanthydrophilization and appearance of surface charges on initially hydrophobic polymer surfaces. It was shownthat the storage of plasma-treated PTFE films in environments with different relative humidity leadsto an increased water contact angle along with a decreased surface potential. The process of hydrophobicrecovery of plasma-treated PTFE films is considered as a consequence of charge relaxation in a humidatmosphere. It was established that surface charging of plasma-treated polymers makes a significantcontribution to their hydrophilicity.
