摘要
聚乙炔(PA)膜作为电极材料实用化的主要困难在于稳定性较差.虽然对这一问题进行了不少研究,但至今成效不大.我们从提高聚乙炔膜的强度、导电性及整体电流分布出发,用冷等离子体方法首次合成了碳纤维复合聚乙炔膜.结构分析结果表明,在复合膜中碳纤维和聚乙炔形成了一定程度的接枝,其空气和热稳定性均高于纯PA膜.用这种膜构成的p-型电池具有较高的化学掺杂度,各项电性能均有所提高.
Polyacetylene/carbon fibre composite film has been synthesized by polymerizaiton ofacetylene on carbon fibre treated with cold plasma tecbnique.Scanning electron micrographsshowed that some graft-copolymer may be formed on the surface of the carbon fibre. Thestability to air and the thermostability of the composite film were better than that of thepure polyacetylene film. The degree of oxidation, energy density, power density and shortcurtent of the cell consisted of composed polyacetylene film are also better than those ofthe cell composed of pure PA electrode.
