The Effects of PANI Concentration on the Mechanical Properties of PP/PANI Composites

Abstract

In this study, the effect of PANI additive with different concentrations (0.3-3.0 wt.%) on mechanical properties of Polypropylene/Polyaniline (PP/PANI) film composites have been investigated. The composites films obtained from the hot pressing technique have been characterized to determine their surface properties and structural morphology (SEM and FT-IR), thermal properties (TG). The effects of PANI additive on mechanical properties of polypropylene have been examined by tensile tests. In particular, tensile strength, Young's modulus and percentage strain at break of the composites have been tested. According to our results, it has been observed that the PANI additive in polypropylene had a significant impact on its mechanical properties. The tensile strength has been reached highest value in PP/0.6 wt.% PANI composites.
