Development of a Sustainable Resource Based Conducting Composite of Polyaniline‐Poly(esteramideurethane)

Abstract

Polymers synthesized from coconut oil as a precursor find scarce applications. Polyesteramide urethane synthesized from coconut oil, a natural resource, is a dough‐like material, unusable in our study. Upon loading with polyaniline it becomes tough and flexible. Composites of ClO₄ ⁻ doped polyaniline with coconut oil based poly(esteramide urethane) (CPEAU) were prepared by a solution blending technique, using different ratios of polyaniline(2 wt%, 4 wt% and 8 wt%). The composites were further characterized by FT‐IR, DSC, TGA, XRD, and SEM. Conductivity was found to be in the range 2.5×10⁻⁵−5.7×10⁻⁴ S cm⁻¹. The composite was found to show weak hydrogen bonding interactions between PANI and CPEAU at 8 wt% loading.
