Abstract


The fabricatiOn of nanomaterials has been one of the focuses of nanotechnology since their unusual physical and chemical properties and DOtential applications in electronics，optics，mechanics，biology,medicine and catalysis． Employing appropriate templates to synthesize nanomateriaIs is a welcome technique．With the development of colloid and interface science，many kinds of ordered aggregation of amphiphilic surfactant have been considered the efficient“soft template”to prepare nanoparticles． In mis article.different soft templates formed by sodium dodecyl sulfate(SDS)，nonyl phenol polyethyleneoxy ether(oπ-1 0)and cetyltrimethylammonium bromide(CTAB)were used to fabricate Ag and BaW04 nanoparticles having different morphologies．We demonstrated the preparation BaW04 and ZnO nanoparticles with novel morphologies through a simple a quatemary microemulsion—medimed hydrothermal procedure．The influences of the hydrothermaltreating time and the concentration of surfactant on the morphology were also discussed． We obtained polypyrrole(PPy)nanoparticles in SDS and sodium dodecyl benzene sulfate(SDBS)micellar solution．At the same time，a simple method to adjust the conjugating structure of PPy molecular and to improve the conductivity of PPy nanoparticles has been found，and the rules in this adusting process were studied．At low temperature we fabricated PPy nanotubes with high aspect-ratio in SDS micellar solution． The procucts were characterized by transmission electron microscope (TEM)．scanning electron microscope(SEM)，infrared spectra(IR)，Ultra Violet．visible spectra(UV．vis)，Raman spectra(Raman)，X-ray diffraction (XRD)，thermogravimetric analysis(TGA)，and electrical conductivities were measured by four—probe technique．
