等离子体聚合是一种仅在等离子体条件下使物质进行聚合的特殊过程,是研制各种功能膜的新途径。等离子体是部分或全部电离的气体,一般由电子,离子和中性基团(自由基、原子、分子)所组成,由于电子密度和离子密度相等且在磁场中具有独特的物理性质,故被称为物质第四态。发现等离子体聚合能形成薄膜的历史可追溯到1874年,但一直把聚合物当作令人讨厌的副产物而未受到重视,直到二十世纪六十年代,等离子体聚合才发展成为一 Plasma polymerization is a special process that polymerizes substances only under plasma conditions and is a new way to develop various functional membranes. Plasma is a gas that is partially or totally ionized. It generally consists of electrons, ions, and neutral groups (radicals, atoms, molecules). Since the electron density and the ion density are equal and have unique physical properties in the magnetic field, Known as the fourth state of matter. The discovery that plasma polymerization can form thin films dates back to 1874, but polymer has been neglected as an objectionable byproduct until the 1960s when plasma polymeriza- tion developed to one
