Photocatalysis and wave-absorbing properties of polyaniline/TiO2 microbelts composite by in situ polymerization method

Polyaniline (PANI)/TiO2 composite is prepared by in situ polymerization of polyaniline on the surface of TiO2 template obtained by the sol–gel process via cotton template. The TiO2 microbelts are prepared by sol–gel method using the absorbent cotton as template for the first time. Then the TiO2 microtubules are used as template for the preparation of polyaniline/TiO2 composites. The structure, morphology and properties of the composites are characterized with scanning electron microscope (SEM), IR, Net-wok Analyzer. A possible formation mechanism of TiO2 microtubules and polyaniline/TiO2 composites has been proposed. The effect of the mol ratio of polyaniline/TiO2 on the microwave loss properties and photocatalysis properties of the composites is investigated.
