Polyaniline/polyaniline coated short nylon fibre/natural rubber (PANI/PANI-N/NR) and PANI/NR conductive polymer composites (CPCs) were prepared by mechanical mixing on a two-roll mill. PANI-N provides both conductivity and good mechanical properties to the CPCs. Such CPCs exhibiting improved mechanical properties are anticipated to have numerous applications in various devices. The frequency and temperature dependence of dielectric properties of polyaniline (PANI), natural rubber (NR), PANI/NR and PANI/PANI-N/NR CPCs in the frequency range 0.1 to 8 MHz and in the temperature range of 303 to 393 K, were investigated. Different theoretical equations and mixture equations were applied to fit the observed dielectric data of the prepared CPCs.
