Preparation of Plasma Polymerized Films in D.C.Glow

本项目的目的是研究在直流辉光条件下的等离子体聚合，这是迄今为止尚未研究的。1）单体不需要特殊的官能团，如乙烯基聚合。选择萘和氟化萘作为可升华单体，研究了等离子体聚合条件，如电压和气体压力。结果表明，单体的化学结构被完全破坏，薄膜表面出现氧化结构。2）将苯及其含氟衍生物引入等离子体聚合。在这种情况下获得的碳的结构不同于由萘制备的碳。表面能随单体中氟原子数的增加而降低。3）硅氧烷衍生物等离子体聚合制备透明碳-二氧化硅薄膜。薄膜的润湿性较低，聚合物薄膜表现出优异的气体分离能力。4）使用有机钛和卤代钛和锡作为单体。5）以咪唑和乙烯基咪唑为单体，制备了一种新型的金属氧化物薄膜。乙烯基咪唑具有荧光行为，而咪唑没有。6）成功地引导两种不同的气体来制备倾斜材料，

The purpose of the project is to investigate plasma polymerization under D.C.glow conditions, which has not been studied so far.1) The monomers are not required special functional groups for polymerization such as vinyl group. Naphthalene and fluorinated naphthalenes were selected as the monomers, which were sublimable monomers, to investigate plasma polymerization conditions such as voltage and gas pressure. It was found that the chemical structure of the monomers was completely destroyed, and oxidized structure was found at the surface of the films.2) Benzene and its fluorinated derivatives were conducted to the plasma polymerization. Structure of the carbon obtained in this case was different from the carbon prepared from naphthalene. The surface energy decreased with increasing the number of the fluorine atoms in the monomers.3) Siloxane derivatives were plasma polymerized to produce transparent carbon-silica films. Wetability of the films was low, and the polymer films showed excellent gas separation ability.4) Organic and halogenated titanium and tin were used as the monomers. The films obtained consisted of the metal oxide.5) Imidazole and vinylimidazole were selected as the monomers. Vinylimidazole afforded fluorescent behavior, but imidazole did not.6) Two different kind of gases were successfully conducted to make inclined materials,
