silver-polyaniline (ag-pani) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (aot) solution as an emulsifier. the synthesis of silver-polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (aot), concentration of oxidation agent and c...

Nanocomposite of polyaniline (PAn) containing nanometre size Sb2O3 was prepared in aqueous media in situ chemical oxidative polymerization method at room temperature in the presence of hydroxypropylcellulose (HPC) as a surfactant. The ability of product to removal of lead ions from aqueous solution was studied. The chemical structure and morphology were studied by fourier transform infrared (FT...

Poly (ether) urethane close/open cell (PEUCC/PEUOC) has been prepared by using in situ polymerization approach. The third-order optical nonlinearities of dissolved samples in DMF were characterized by Z-scan technique at the measurement wavelength of 532 nm. The synthesized samples were also examined by optical microscopy and UV-Vis absorption spectroscopy. The nonlinear refractive (NLR) indice...

Vinyl ether (VE) was long believed to be among the monomers that could not radically homopolymerized. Therefore, synthesize block copolymers with versatile polymerizable monomers, efficient transformation reactions were necessary between living cationic and controlled radical polymerizations. Under such circumstances, some groundbreaking polymerizations have been discovered. One reaction, a met...
