Microcomposites of zirconium phosphonates with a conducting polymer, polyaniline: Preparation, spectroscopic study and humidity sensing

Popis výsledku v původním jazyce

The microcomposites of polyaniline with layered zirconium 4-sulfophenylphosphonate, 2-sulfoethylphosphonate, 4 carboxyphenylphosphonate and carboxymethylphosphonate were prepared and characterized by powder X-ray diffraction, FTIR and Raman spectroscopies. Two methods of aniline oxidation, using peroxydisulfate anion, cerium(IV) or iron(III) cations as aniline oxidants, were tested. FTIR and Raman spectra suggest that the intercalated aniline does not polymerize. Polyaniline grows on phosphonates during surface polymerization rather than to be generated as a free polymer in the bulk of reaction mixture. Conductivity of composites varied from 10−9 S cm−1 to 10−3 S cm−1 depending on the way of preparation and the type of the phosphonate filler. The conductivity response to the ambient humidity strongly depends on the filler and suggests the possibility to apply these materials in humidity sensors.
