Модификация поверхности поливинилового спирта и политетрафторэтилена методом ионной имплантации

Abstract

The effect of silver, carbon and argon ion implantation with dose of 1•10{16} ion/cm{2} on physical-chemical surface properties of polyvinyl alcohol (PVA) and polytetrafluoroethylene (PTFE) has been investigated. Elemental compositions of the modified surface layer were researched by the methods of infrared spectroscopy (IR- spectroscopy) and X-ray photoelectron spectroscopy (XPS). Physical-mechanical properties of initial and ion implanted PTFE were studied by the limiting wetting angle, microhardness and surface resistivity measurements. Wettability and microhardness are observed to enhance and to decrease in the case of the PTFE and PVA implanted samples, respectively. Surface resistivity is revealed to be approximately the same as initial state of these materials.
