摘　　要：Polyaniline thermal doped with dodecylbenzene sulfonic acid was found to form a liquid-crystalline solution in m-cresol. A polarizing optical microscope and X-ray diffraction measurement were used to study the texture of liquid-crystalline phase. The doped methods had a great effect on the solubility of PAN-DBSA in organic solvents and the appearance of lyotropic liquid crystal of PAN-DBSA solution. An ordered smectic structure with a layer spacing of d=3. 309 nm can be observed for the thermal doped PAN-DBSA in m-cresol.Polyaniline thermal doped with dodecylbenzene sulfonic acid was found to form a liquid-crystalline solution in m-cresol.
