Synthesis, characterization and electrical conductivity measurement studies of poly-o-anisidine Sn(IV) phosphate [POASn(IV)P] nano-composite cation-exchange material

A nano-composite inomeric poly-o-anisidine Sn(IV) phosphate [POASn(IV)P] was prepared via sol–gel mixing of an electrically conducting organic polymer, poly-o-anisidine with the matrices of inorganic precipitate of Sn(IV) phosphate. The physico-chemical properties of the material were determined using AAS, CHN elemental analysis, UV–vis spectrophotometry, FTIR, TGA–DTA, TEM, XRD and SEM studies. Electrical conductivity studies were carried out by four in-line probe DC electrical conductivity measuring instrument. The conductivity was found within the range of semiconductor region (10−3 to 10−2 S/cm). Isothermal and cyclic techniques were also used to understand the stability in terms of DC electrical conductivity retention.
