摘要
A method for preparing organic-inorganic hybrids containing organophosphorus compounds, silica, and polyaniline (PANI) was developed using sol-gel technique. This method allows the in situ synthesis of organic-inorganic hybrids by reacting tetraethoxysilane (TEOS), aniline, initiator, organophosphorus compound in formic acid. The formic acid has multiple functions: as solvent and acidic media for polymerization of aniline and reagent for sol-gel process. The use of an organophosphorus compound as coupling agent and the introduction of a conductive polymer in silica matrix was investigated.
