title: Controllable synthesis of aniline oligomers into uniform, dispersed cross and needle morphologies.
abstract: Two kinds of homogeneously dispersed aniline oligomer assemblies, namely "cross" and "needle" morphologies, can be conveniently synthesized on a large scale in a near-neutral aqueous medium using sodium dodecylsulfate (SDS) as a surfactant. The effects of oxidant type, premixing time, amount of SDS, monomer concentration, and temperature on the final morphology were investigated in detail. A possible mechanism for the formation of both "cross" and "needle" structures is given.
