A colloidal templating method with vapor-phase oxidative polymerization was used to fabricate conducting poly(pyrrole) (Ppy) inverse opal patterns over a wide area. We fabricated 2- and 3-D poly(pyrrole) (Ppy) inverse opal patterns from two kinds of 2- and 3-D colloidal templates of poly(St/NaSS) latex particle, which were prepared on bare glass and 3-aminopropyl trimethoxysilane (APTMS)-modified glass substrates, respectively. With two different 2-D colloidal templates, different Ppy inverse opal monolayer patterns, i.e., ordered 2-D rings, hexagonal or honeycomb monolayer, were obtained. With 3-D colloidal templates, Ppy inverse opal multilayers were obtained and their time-evolution growths were observed by SEM analysis. Differences in inverse opal structure and volume fraction were elucidated in terms of the array pattern of sacrificial poly(St/NaSS) latex particles and its packing density. Shrinkage of the inverse opal structure, which might be a serious problem in optical and physical properties, was reduced to almost zero with this method. Mechanical and electrical properties of the Ppy inverse opal multilayer films were analyzed by nano-indentation and 4-point probe conductivity methods, respectively. It was found that narrow inter-particle interstices of colloidal templates led to honeycomb-like 2- and 3-D patterns, higher modulus and hardness, and lower electrical conductivity. On the contrary, a spacious colloidal pattern resulted in 2-D ring patterns, hexagonal 2- and 3-D patterns, lower modulus and hardness, and higher electrical conductivity.
