One-dimensional (1D) electronic materials with inherent nanoscale features are considered to be promising components for achieving unprecedented future technologies. Much effort has been devoted to the synthesis of inorganic nanomaterials and, as a result, unique size- and structure-dependent properties have been identified in those nanomaterials. Owing to the technical difficulties in fabricating and manipulating them, however, relatively little research has been done on the applications of polymeric nanomaterials. Moreover, there is still a lack of a theoretical interpretation as to how the polymerization proceeds at the nanometer regime. Conducting polymers may be an alternative materials against metals and inorganic semiconductors in future applications. Here, we prepare multidimensional conducting polymer nanomaterials using single-nozzle co-electrospinning, followed by vapor-deposition polymerization. We, for the first time, suggest the concept that the morphology of deposited polymer nanomaterials is subject to substrate curvature, as well as synthetic conditions. Nanonodules and nanorods were grown on a nanofiber surface by controlling critical kinetic factors such as temperature and pressure during vapor deposition polymerization, leading to the formation of multidimensional polymer nanostructures.
