摘要

The anti-bacterial property of hydrogen-ion and oxygen-ion treated polytetrafluoroethylene (PTFE) materials is determined using contact angle measurements, scanning electron microscopy (SEM), and Escherichia coli (E. coli) adhesion tests. PTFE samples are irradiated using a gas discharge ion source (GDIS). Ion energies are varied by changing the plasma discharge current (Id). Results show that both the hydrogen and oxygen plasma treatments modify the PTFE surface in morphology. Both treatments exhibited changes in the wettability of the samples at different Id, Hydrogen treatment shows that lower Id improved material hydrophobicity and higher Id resulted in enhanced hydrophilicity, while oxygen treatment shows that as the Id increases, PTFE becomes more hydrophilic. The hydrogen and the oxygen treated PTFE exhibited a reduced E. coli attachment on the samples. Oxygen treatment exhibited a lower E. coli adhesion as compared to using hydrogen.
