The Coal Oxidized by HNO3 on the Conductivity Effect of Coal-Based Polyaniline
The interation between aniline and shenfu-coal(SFC) was studied by the changes about acidic functional groups and the absence of coal macromolecules. The results showed that the acid content in coal is increased by HNO3, the conductivity of OCPANI, HNO3-OCEX-PANI, as well as SFCEX-PANI is lower than SFC-PANI. The macromolecular structure of the SFC play an important role,the macromolecular acid in coal only play the weak doping role.
