“…6À9 Following this approach, material scientists have sought to develop novel composites using many polymer/nanoparticle composite systems. 10À15 Some examples are ZnO/ PMMA, 16,17 ZnO/poly(hydroxyethyl methacrylate), 18 Al 2 O 3 / polycarbonate, 19 TiO 2 /poly(vinyl alcohol), 20 CdS/PS, 10 CdS/ PMMA, 21 ZrO 2 /PMMA, 22 CdTe/PS, 23 and BaTiO 3 /polyimide. 24 However, the refractive indices (RIs) of polymers and inorganic particles are usually different.…”
