摘要

Electrically conductive polyaniline(PANI) and its blend with polycarbonate (PC) was prepared by one-step emulsion polymerization technique in which sodium lauryl sulfate(SLS) acts as surfactant and as a protonating agent for the resulting polymer.The prepared PANI and its blends were characterized by density .percentage of water absorption .and electrical conductivity .PANI-PC blend exhibits a conductivity value of 4.70X 10~(-2) S/cm(PANI-PC1) and 5.68X10~(-5) S/cm(PANI-PC3)with a change in dopant from p-toluene sulfonic acid(TSA)to SLS,respectively.By using a more general method,which takes into account the presence of disorder of the second kind in polymers proposed by Hosemann,crystal size() and lattice strain(g in %) values were estimated.The variation of conductivity in doped PANI and PANI-PC blend has been explained on the basis of these microcrystalline parameters.TGA thermograms of PANI and PANI-PC blend show three-step degradation behavior.Thermal stability of PANI was improved after blending with PC.
