Preparation And Characterization Of Nanometer-Sized AgCl-PMMA Hybrid Material

Nanoparticls have become one of the quite popular subjects in materials research fields owing to their many peculiar properties in optics, acoustics, electricity, magnetics, heat, catalysis, mechanics, chemical activity, etc,and their great potential high technology applied prospects. Inorganic-organic nanometer hybrid materials summarize the characteristics of inorganic material,organic material and nanomaterial,so they have new applications in many fields such as electronics, chemistry, catalyst, mechnics, biochemistry,etc. Silver halide which has good light sensitivity is widely used in photochromic materials and photographic emulsions. In this dissertation,the hydrosol of CuO, AgCl and AgI were prepared by precipitation method,while Cu2O by Oxidation-reduction. The effect factors on hydrosol were discussed and analysed . AgCl , Agl and CuO organosol were obtained by using oleic acid to extract and modify the nanoparticles in hydrosols. The effect factors on organosol were discussed extensively.AgCl organsol,AgCl and CuO organosol were mixed with MMA. After polymerization was carried out, nanometer hybrid material having photochromism was synthesized. The prepared samples were deeply investigated by TEM,SEM ED XRD, TGA-DTA, etc.
