摘　　要：与传统的质子酸掺杂相比，采用具有功能性的两亲大分子对聚苯胺（PAN）掺杂，可以使产物的加工性和稳定性大大提高［1～3]．十二烷基苯磺酸（DBSA）是研究得比较多的掺杂酸之一，其掺杂过程一般都采用辅助溶剂，由此而引起PAN与DBSA结合程度低、掺杂效率低、溶剂需后处理?..The distinguishing features and structures of polyaniline thermal doped with dodecylbenzenesulfonate at different temperatures without the use of auxiliary s0lvent have been investigated. The exothermic complexion has been observed during doping process at elevated temperature by calorimeter studies, which results in the formation of a transition responslble for the del0calized polarons observed by UV-Vis spectrum. The resulting complex is shown to form a layered structure with strongly anisotropic characteristics as determined by X-ray diffraction measurement.
