| Abstract: | In this study, the effect of polyaniline (PANI) as filler has been investigated on the mechanical and thermal properties of blends of cis‐polyisoprene (CPI) and trans‐polyisoprene (TPI) by dynamic mechanical analyzer and transient plane source technique, respectively. The samples blend composites with different concentration of PANI have been prepared by solution casting method and characterized through X‐ray diffraction. Experimental results from mechanical and thermal measurements show that incorporation of PANI in CPI/TPI blends increases glass transition temperature, mechanical properties and thermal properties whereas decreases damping property. This increase in different properties is only upto a certain amount of PANI and over this amount an entirely apposite behavior is observed. This observed behavior of mechanical and thermal properties is explained on the basis of crystallinity and crosslink density. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers |
