Abstract

Eigenstate polyaniline (PANI) were prepared by in-situ polymerization method，and under the same experimental conditions, composites doped with attapulgite、vermiculite and diatomite were prepared respectively. The exist of additive materials of attapulgite、vermiculite and diatomite acted as the skeleton of PANI. The samples were characterized by FTIR、XRD、SEM、UV spectrophotometer and TGA. The results revealed that the composites which have the structure of attapulgite and the nature of the polyaniline. The composites doped with attapulgite、vermiculite and diatomite had better excellent adsorption Capacity in 100-160℃for acid gas such as CO₂、SO₂ and NO₂ under TGA than that of PANI modified with nothing. This property of PANI-based materials has a great importance significance for dealing with the fuel gas in thermal power industry to protect environment.
