THE EFFECT OF LOW TEMPERATURE OXYGEN PLASMA ON SURFACE OF PVA MEMBRANE |
| |
| Abstract: | The surface of polyvinyl alcohol pervaporation membrane was modified by low tmeperature plasma with oxygen. The effects of exposure time, discharge current and pressure on its hydrophilicity were investigated by means of contact angle measurement and IR spectra. The results show that low temperature plasma treatment can substantially alter the surface properties of PVA membrane by ways of increasing the amount of polar functional groups exposed on the sample surface thus enhacing its hydrophilicity. |
