Synthesis And Characterization Of Nanocomposite Materials Assisted By Amphiphilic Molecules

Nanomaterials have many unique physical, chemical and mechanical properties, which are different with the usual materials, composites from conducting polymers and metal nanoparticles are attractive materials as they combine the properties of low dimensional organic conductors with high surface area materials together and their unique electrical, thermal, mechanical, and optical properties, so they have been exploited for the extensive potential applications in optics, electronics, magnetics, catalyst, sensing, biomedicine, microreacter, etc.Recently, the scientists had synthesized many inorganic materials, organic materials, and inorganic /organic composites, with the assistance of surfactants.This paper use APS, AgNO3, FeCl3, CuCl2 as oxidant, synthesize Ag/PCz Fe₂O₃/PCz, TiO₂/PCz, CuO/PCz using a one-step process by colloid chemical route. We have discussed the effection of concentration factor, time factor and so on. The excellent function of PVP in the process of synthesizing the composites is also discussed rationally. The products have been characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), and X-ray diffraction (XRD) and Photoluminescence spectra (PL), UV-vis spectra (UV-vis), Infrared spectra (IR). The forming of the PCz spheres is an Ostwald ripening process. The luminescence intensity of the composite is about 6 times of that of the polymer. The Ag/PCz composites absorption peak showed new peaks in the long-wave direction. As an anchor agent, PVP play an important role in synthesizing series of composites. Relative to traditional electrochemical method to prepare composites of carbazole, colloid chemical route is simple, low cost and environment-friendly.
