英文摘要: Polyaniline/alpha-Al(2)O(3) (PANI/alpha-Al(2)O(3)) composites were synthesized by in situ polymerization through ammonium persulfate ((NH(4))(2)S(2)O(8), APS) oxidized aniline using HCl as dopant. XRD and FTIR were used to characterize the PANI/alpha-Al(2)O(3) composites. The thermal stabilities and glass transition temperature (T (g)) of PANI/alpha-Al(2)O(3) composites were tested using thermogravimetric (TG) method and modulated differential scanning calorimetry (MDSC) technique. The results of TG showed that the thermal stability of PANI/alpha-Al(2)O(3) composite increased and then decreased with the increase in alpha-Al(2)O(3) content. The derivative thermogravimetry (DTG) curves showed one step degradation of PANI when the alpha-Al(2)O(3) content was lower than 52.5 mass%, and exhibited two steps degradation when the alpha-Al(2)O(3) content was higher than 63.6 mass%. The MDSC curves showed that the T (g) of PANI/alpha-Al(2)O(3) composites increased and then decreased with the augment of alpha-Al(2)O(3) for the interaction between PANI chains and the surface of alpha-Al(2)O(3).
