摘要：

We present an analysis of electron spin resonance, magnetic susceptibility, and de conductivity measurements on polyaniline and polyaniline-PMMA blend to understand the reason for enhanced N(E-F) in the case of the blend. A number of experiments performed under different conditions can be understood using a model in which metallic particles are surrounded by disordered regions or shells. Our results are in agreement with an earlier investigation that found different structural arrangement in the blend compared with polyaniline.
