Synthesis and characterization of polypyrrole/TiO2 composite by in situ polymerization method

Polypyrrole/TiO2 composite is prepared by in situ polymerization of pyrrole on the TiO2 template. The TiO2 microbelts are prepared by sol–gel method using the absorbent cotton template for the first time. Then the TiO2 microbelts are used as template for the preparation of polypyrrole/TiO2 composites. The structure, morphology and properties of the composites are characterized with scanning electron microscope (SEM), IR and Network Analyzer. A possible formation mechanism of TiO2 microbelts and polypyrrole/TiO2 composites has been proposed. The effect of the molar ratio of pyrrole/TiO2 on the photocatalysis properties and microwave loss properties of the composites is investigated.
