The studies to embed metal nanoparticles into polymeric matrices have become an interesting issue due to a lack of stability of free metal nanoparticles which exhibit distinct electrical, optical, and biomedical properties. The homogeneous hybrid nanocomposites of silver nanoparticles (AgNP) and sodium deoxycholate (NaDOC) were prepared by pH-induced self assembly as a novel method. Their dispersion stability of free silver nanoparticles (0.01M, Raverage=8nm) was improved by a sol-gel transition of NaDOC (0.06M) hybrid hydrogel and their immobilized nanoparticles were analyzed by OM and TEM microscopy. A sol-gel transition was controlled by polyacrylic acid (PAA) as a pH modulator and a stabilizer in the range from pH 6.9 to 7.0. In this presentation, aligned Ag nanowire fabricated by self-assembled material will be presented. |
