Relationship between Morphology and Electrochemical Properties of Polyaniline in the Nanometer Regime

Lee Y., Yoon H., Chonnam National University, KR

Polyaniline (PANI) has found a wide range of applications due to its electrical properties, reversible redox behaviors and environmental stability. Here, we report the preparation of PANI nanostructures with three different aspect ratios, namely, nanospheres, [...]

Kinetically Controlled Formation of Deposited Polymer Nanomaterials with Unique Surface Substructures

Choi H., Yoon H., Chonnam National University, KR

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 [...]

Conjugated Polymer Papers for Metal Ion Detection

Ahn K-J, Yoon H., Chonnam National University, KR

It is of great importance to detect heavy metal ion in solution. Here, we describe the electrochemical detection of metal ions using polypyrrole/cellulose (PPCL) composite papers in both static and flow systems. A home-made electrochemical [...]

Conducting Polymer Based Adhesives for Electrochemical Applications

Choi H., Yoon H., Chonnam National University, KR

There has been huge demand for developing advanced materials and devices for enhanced energy storage. However, relatively little attention has been devoted so far to the development of efficient binders for electrode materials. In this [...]

Manganese Oxide/Carbon Nanofibers-Embedded Graphene Sheets for Capacitors

Ahn K-J, Yoon H., Chonnam National University, KR

We report the fabrication of a ternary nanoarchitecture consisting of manganese oxide (MnO), carbon nanofibers (CNFs), and reduced graphene oxide sheets and their application to supercapacitor electrodes. MnO nanoclusters-decorated CNFs (MCNFs) with diameters of about [...]
