## Abstract Polyaniline (PAn) dispersed in water was prepared with sodium dodecylsulfonate (SDS) as a surfactant with varying concentrations of aniline and HCl and molar ratios of SDS/aniline. The PAn dispersion was homogeneous and stable, and its pH value could be adjusted. The conductivity of PAn

Polyaniline films were grown on glass supports during dispersion polymerizations of aniline using poly(N-vinylpyrrolidone) and hydroxypropylcellulose as stabilizers. The initiation of polyaniline chains is proposed to be heterogeneously catalyzed by the surfaces immersed in the reaction mixture. Fil
In summary, unique conical carbon filaments supported on vapor-grown carbon microfibers were synthesized by the ironcatalyzed pyrolysis of methane in the presence of hydrogen. The conical filaments exhibit axial cylindrical channels with open tips. A base-growth mechanism with delayed nucleation of
