Dielectric and Conductive Characteristics of Polyaniline Coated Short Nylon Fiber Chloroprene Rubber Composites: A Comprehensive Study on Frequency, Temperature and Loading Dependencies

Abstract

In delving into the realm of conducting polymer composites (CPCs), specifically focusing on polyaniline (PANI), polyaniline coatedshort fibers of nylon (PANI-N) and chloroprene rubber (CR), this study takes an exploratory journey. Blending PANI/PANI-N/CR andPANI/CR CPCs mechanically, while adding short nylon fibers significantly improves their mechanical strength. These strong and  durable CPCs possess significant promise for a wide range of applications in various devices. Present research methodically probes the  dielectric features of CR, PANI/CR and PANI/PANI-N/CR composites across a frequency range of 0.1 to 8 MHz and a temperature span  of 303 to 393 K. The results highlight potential correlations between mechanical properties and dielectric behaviour, paving the way for tailored approaches in developing high-performance conducting polymer composites for advanced applications. The study also utilizes  theoretical equations and mixing models, which ensures a rigorous validation process that enhances accuracy.
