With the increase in SD of the SPAN, its conductivity(σ)decreases but its solubility is improved. UV-Vis spectra indicate that SPAN has a red shift compared with PANI. The colloid aggregates and loose structure have been found by using TEM.展开更多

Under UV irradiation, the bond nature between layers turns from ionic to covalent following the decomposition of diazonium group, and the film gets very stable. The photoelectric conversion property of substituted polyaniline containing self assembled film has also been investigated in this article.展开更多
