摘要：

A detailed magnetic susceptibility study of sulfonated polyanilines, with sulfur-to-nitrogen (S/N) ratio of 0.5 and 0.75 has been conducted in the temperature range 77-450 K under different thermal and sample preparation conditions. This larger temperature range provides new insightful results, including the role of magnetic bipolarons and their destabilization with increasing temperature. A simple exchange coupled pairs model is used for analyzing the experimental data.
