Electrical transport and morphological studies of polyaniline nanostructures

Abstract: Polyaniline nanostructures have been synthesized by self‐assembly method by varying the dopant to monomer molar ratio. High resolution transmission electron micrographs show how the dopant to monomer molar ratio influences on the morphology and structure. The temperature dependence of dc conductivity study shows semiconducting behavior. From dc conductivity study it has been observed that conductivity increases with increasing dopant concentration and maximum conductivity is attained at dopant to monomer molar… Show more

“…The conductivity of pristine PANI increased mildly with increasing temperature as typical of organic semiconductors. 29,30 With more p-PDA introduced into the copolymerization mixture, the room temperature conductivities of the copolymers decreased nearly linearly on a semilogarithmic scale, indicating that the copolymerization products are statistical copolymers instead of a mixture of the corresponding homopolymers. 1,31 The reduction in conductivity corresponds to the shift in dependence in Fig.…”

“…PAni nanostructures can be synthesized with zero dimensions (e.g., nanospheres [3] ), one dimension (e.g., nanofibers [4] , nanorods [5] , and nanotubes [6] ), and two dimensions (e.g., nanobelts [7] and nanosheets [8] ). PAni nanostructures have been widely investigated because they combine the unique characteristics of a conventional polymer with the quantum effects of nanomaterials [9,10] .…”

“…To improve the electric conductivity of epoxy, conducting polymers such as polyaniline (PANI) are blended with the epoxy systems. PANI is the most important conducting polymer due to its facile synthesis, controllable electrical conductivity, and low cost . Moreover, PANI can absorb and reflect the electromagnetic waves and thus it can be used to develop electromagnetic interference (EMI) shielding materials .…”

Moreover, PANI can absorb and reflect the electromagnetic waves and thus it can be used to develop electromagnetic interference (EMI) shielding materials . On the other hand, there is a need for using polymeric materials (as grafting with other polymers) to enhance the conductivity, thermal, and mechanical properties of PANI.…”
