等离子体是部分或全电离的气体,一般由电子、离子和中性基因(自由基、原子、分子)所组成,因其具有独特的物理性质,特别是在磁场中表现出的特性而被称为物质第四态。早在一百多年以前,有人就观察到一些有机物蒸气电离时能够发生聚合的现象,但却一直把聚合物当作反应的副产物而未予重视。直至六十年代初,冷等离子体聚合所制备的薄膜具有高度 Plasma is a partially or fully ionized gas, typically consisting of electrons, ions and neutral genes (free radicals, atoms, molecules) that are said to have their unique physical properties, especially those exhibited in magnetic fields The fourth state for the material. As early as a hundred years ago, some people observed the polymerization of some organic matter when the vaporization of organic vapor, but has been the polymer as a by-product of the reaction and no attention. Until the early 1960s, films prepared by cold plasma polymerization had heights
