Improvement of physico-mechanical properties of coir-polypropylene biocomposites by fiber chemical treatment.

Highlights: [•] Coir-polypropylene biocomposites were manufactured using hot press technique. [•] OH groups in raw coir cellulose were converted to OH−Cr groups during treatment. [•] SEM indicates improved interfacial adhesion between coir and PP upon treatment. [•] Chemically treated composites yielded the best set of mechanical properties. [ABSTRACT FROM AUTHOR]
