摘　　要：通过常压等离子体处理进行PVA失重、PVA浆料在水中溶解率的变化、等离子体处理与常规H2O2退浆比较分析以及PVA薄膜的XPS和FT-IR分析,讨论常压等离子体对PVA作用的机理。结果表明,常压等离子体作用使部分PVA大分子氧化成小分子如CO2、H2O而直接消失在空气中,另一部分PVA大分子被氧化降解成分子链较短的分子,提高了其在水中的溶胀、溶解性。On the basis of measuring PVA＇ s weight loss and the change of dissolution rate of PVA size in water after plasma treatment at atmospheric pressure, a comparison of desizing between the plasma treatment and the traditional H2O2 method was made. XPS and FF-IR analyses of PVA films showed that plasma action led to some PVA molecules oxidized into some molecules such as CO2, H2O which disappeared in the air and the other part of PVA was oxidized and degraded to ones with shorter chains, thus increasing the swelling and dissolving properties of PVA size.
