The present work describes the use of agricultural by‐product of the cocoa pod husk (CPH) as filler in the polypropylene composites. Besides, a green coupling agent (GCA) was developed from the coconut oil for filler modification. The primary objective of using GCA on CPH is to enhance the interfacial adhesion as improved stress transferability in the composites. The overall tensile properties, water absorption, thermal stability, and crystallinity of the composites are significantly improved by the occurrence of GCA. The fracture micrographs via the scanning electron microscopy shows homogeneous distribution of modified CPH particles and better interfacial bonding with matrix which leads to considerable improvement in the properties of the composites. The performance of GCA was comparable with the maleic anhydride grafted polypropylene and silane coupling agent. POLYM. COMPOS., 39:2441–2450, 2018. © 2016 Society of Plastics Engineers
