Study of Photoelectrical Polyaniline/Dye Copolymerization Material

Using direct fast black G,pyromellitic acid dianhydride and polyaniline as raw material,the photoelectrical copolymer-polyaniline/dye interpolymer is synthesized by condensation polymerization.The polymer has high solubility,fine ability to film,and conductivity reaches 10-1S/cm.There are no more different in theory and practice on the mole ratio of N and S by elemental analysis.IR identifies the designed chemical structure of the polymer.The absorption of polyaniline copolymerized with direct fast black G is very intense in the range of visible light and nearinfrared by UVvis spectrum.The photoconductivity of the polymer is greatly enhanced.TGA shows that thermol stability of the synthesized polymer is greatly enhanced over 100.It can be seen from TEM that the polymer is amorphous state.The glass transition temperature of the synthesis copolymer is about 246,which is proved by DSC.
