Copolymerization of vinyl monomers on the surface of CDS and photoconductivity properties of resulting composites

Photovoltaic Properties of Polymer/Fe2O3/Polymer Heterostructured Microspheres

“…Polymer materials maybe a good substance for passivation, since they have large band gaps and low conductivity due to the small number of charge carriers with very low mobility and the high trap density. In the past, many inorganic particles were encapsulated in the polymer layer in order to affect the physical properties of such powders, particularly in terms of increasing their dispersity in solvents or in composite phases. − Only Y. Haga et al found that the photoconductivity of CdS, ZnO, and TiO 2 was affected by the interaction between the polymers and the inorganic phases and the effect upon the electron transport process was thought to be especially large. − In this paper, Fe 2 O 3 nanoparticles with diameters of 3−5 nm were encapsulated in the polymer microspheres in a trilayer core−shell heterostructure. The effect of polymers on its properties were investigated by UV spectroscopy and surface-photovoltage spectroscopy.…”

Trilayer Composite Poly(styrene/butyl acrylate/acrylic acid) Terpolymer Microspheres with Fe2O3 Middle Layer: Synthesis and Characterization

“…Not only the mechanical properties of the composite particles, but also their electrical, magnetic and photoelectric properties are arousing more interest. 8 Haga et al 9 have found that the photoconductivity of CdS encapsulated in polymer is considerably di †erent from that of CdS alone. Di †erent monomers do not lead to the same results, because of the interaction between polymers and the inorganic phase.…”
