| Abstract |
The synthesis of novel materials with improving property and performance is a continually expanding frontier of materials science. In this regard composite materials, composed of organic/inorganic components, exhibit beneficial properties originating from each component and satisfy the economical and environmental challenges of the industry. Especially, conducting polymer based nanocomposites have been used as sensor transducers owing to their conjugated polymer backbone structures comprising alternating single and double bonds. In this presentation, we suggest two types of nanocomposites that are platinum-decorated polypyrrole nanoparticles and porous palladium layer coated polypyrrole nanoparticles, respectively, to apply electrochemical sensor systems such as dopamine non-enzyme biosensor and hydrogen gas chemical sensor transducer. As a result, these composite based-sensor electrodes exhibit ultrahigh sensitivity and stability toward each analytes due to the unique morphology of the noble metal components in the composite structure. |
