This paper focuses on the PVP / PAn, PAA / PAn multilayer films and water-soluble CdS nanoparticles prepared by self-assembly of particles , the main contents are as follows : 1. Based on intermolecular hydrogen bonding layer self -assembly technique using the prepared PVP / PAn self-assembled multilayer film by UV - visible spectroscopy , infrared spectroscopy , atomic force microscopy , scanning electron microscopy , X- ray reflection spectra by means of the self-assembled multilayer assembly process , the film driving force , surface morphology , structure and thickness discussed in detail ; 2 in the PAA and PAn intermolecular hydrogen bonding and electrostatic forces working together through the layers of self-assembly technique was successfully prepared PAA / PAn since the group multilayer film , the self- assembled monolayer while achieving for the acid doped polyaniline by UV - visible spectroscopy, infrared spectroscopy , atomic force microscopy , scanning electron microscopy , X- ray reflection spectra by means of the self-assembled monolayer growth process , formation mechanism , surface morphology, structure and characterization of film thickness were analyzed : 3. prepared CdS nanoparticles modified with oleic acid , and then use β- cyclodextrin with oleic acid -based molecular recognition of self-assembly to form the main - guest complex method to achieve the right CdS modification of the surface of the nanoparticles obtained in neutral aqueous dispersed , good stability nano- CdS, by infrared spectroscopy , X- ray diffraction , atomic force microscopy , UV - visible spectroscopy, fluorescence spectroscopy, fluorescence microscopy and other means of the preparation of water-soluble CdS nanoparticles were characterized , a preliminary study of the water-soluble nano- CdS phase transfer process , β- cyclodextrin concentration on nano- CdS phase transfer processes of water-soluble nano- CdS particles fluorescence properties.
