摘要
Using layer-by-layer self-assembly technique,we have successfully constructed nanostructured composite films of conjugated polymer (sulfonic acid ring substituted polyaniline, SPAn)/ semiconductor nanoparticles(Q-CdS).The processes synthesis have been studied by UV-Vis, contact angle measurement, XPS and AFM techniques.The results indicated that the self-assembly processes were dependent on the pH of the solution of each component and the doping time.It has been found that the roughness of the assembled nano-composite films increases as the layer number increases.The main reason can be attributed to the generation of adsorption defects from partially adsorbed film surface in film fabrication processes.

It has been found that the roughness of the assembled nano-composite films increases as the layer number increases. The main reason can be attributed to the generation of adsorption defects from partially adsorbed film surface in film fabrication precesses.
