| Abstract: | The self-assembly behavior of the amphiphilic block copolymer poly(methyl methacrylate)-block-poly(lead dimethacrylate)(PMMA-b-PLDMA) with cross-linked hydrophilic block(PLDMA) in ethanol was investigated. The results show that the size and morphology of the resulting micelle or micellar aggregates are ascribed to the content of ethanol and the nature of the solvent mixture. PbS nanoparticles were formed in the micelle by in situ reaction with H_2S gas. The morphology and size of the self-assembly objects were investigated using scanning electron microscopy(SEM) and transmission electron microscopy(TEM). |
