Mechanism of polypyrrole and silver nanorod formation in lauric acid-cetyl trimethyl ammonium bromide coacervate gel template: Physical and conductivity properties

▶ Coacervate gel as template for silver and polypyrrole nanorod synthesis. ▶ Nanorod formation of Ag begins from the first instant while that of PPy takes a longer time. ▶ Dc conductivity of PPy-Ag composite is seven orders higher than that of the PPy nanorods. ▶ PPy-Ag systems indicate Ohmic behavior while the PPy nanorods exhibit semi-conducting behavior. ▶ Increased gel concentration decreases the average diameter of PPy nanorod by 50% while that of Ag nanorod decreases only 12%.
