Photocatalytic and microwave absorbing properties of polypyrrole/Fe-doped TiO_2 composite by in situ polymerization method

摘要

The Fe-doped TiO_2 microbelts were prepared by sol-gel method using the absorbent cotton template for the first time. Then the Fe-doped TiO_2 microbelts were used as templates for the preparation of polypyrrole/Fe-doped TiO_2 composites. Polypyrrole/Fe-doped TiO_2 composites were prepared by in situ polymerization of pyrrole on the Fe-doped TiO_2 template. The structure, morphology and properties of the composites were characterized with scanning electron microscope (SEM), FTIR, Net-work Analyzer.
