Abstract

This paper discuss the preliminary result for surface characteristic of polytetrafloroethylene (PTFE) after atmospheric plasma treatment. An atmospheric pressure plasma system has been assembled and the effect of helium plasma treatment on PTFE surfaces was studied by scanning electron microscope (SEM). The contact angle of PTFE surface after helium plasma treatment were measured and recorded. Results showed that the contact angle of sample decreased with the increase of helium plasma treatment time. Also, relative increment of surface hydrophilicity could be optimized by the plasma conditions. Based on the preliminary findings, atmospheric plasma with helium as a working gas treatment on the PTFE surfaces improved the surface hydrophilicity and increased the surface area of the sample.
