Abstract

The influence of oxygen plasma on the wettability of polytetrafluoroethylene (PTFE) materials is determined using contact angle measurements and scanning electron microscopy (SEM). PTFE samples are irradiated using oxygen low-energy gas discharges using a gas discharge ion source (GDIS) facility with ion energies varied by changing the plasma discharge current (Id) at intervals of 1mA from 1mA to 3mA. Results show that oxygen plasma treatments modify the PTFE surface in morphology; it also exhibited changes in the wettability of the samples at different Id, lower Id improved material hydrophobicity while higher Id resulted in enhanced hydrophilicity.
