Abstract

The porosity and hydrophobic properties of Hydrogen ion treated Polytetrafluoroethylene materials (Teflon) are determined using optical characterization. Such materials are irradiated using a low energy hydrogen ion shower (LEHIS) of a Gas Discharge Ion Source (GDIS) system. During treatment, H⁺ ions dominate over H₂⁺ ions based on the ion beam used. The duration of treatment and the gas discharge current are varied to obtain vary the characteristics of the treated Teflon. After treatment, we analyze the transmittance to quantify the porosity and consequently the hydrophobic property of the treated materials. Transmittance showed that when low current discharge plasma is applied on the sample its hydrophobic property is enhanced. The transmittance changes due to the mechanical effect of stretching the samples but the wettability was not changed.
