Eigenstate polyaniline (PANI) were prepared by in-situ polymerization methodï¼?and under the same experimental conditions, composites doped with attapulgiteã?vermiculite and diatomite were prepared respectively. The exist of additive materials of attapulgiteã?vermiculite and diatomite acted as the skeleton of PANI. The samples were characterized by FTIRã?XRDã?SEMã?UVÂ 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 attapulgiteã?vermiculite and diatomite had better excellent adsorption Capacity in 100-160â??for acid gas such as CO2ã?SO2 and NO2 under TGA than that of PANI modified with nothing. This property of PANI-basedÂ materials has a great importance significance for dealing with the fuel gas in thermalÂ powerÂ industry to protect environment.
