ABSTRACT

Aim of the study: This study set out to create an environmentally sustainable composite using natural rubber (NR). latex, vinyl acetate and rapeseed plant straw by investigating the impact of functionalizing natural rubber on the resultant composite's characteristics.

Design/Methodology: Acid hydrolyzation of α-cellulose derived from the straw of the rapeseed plant was used to prepare nanocellulose. Then a ternary nanocomposite based on NR, nanocellulose, and polyvinyl acetate (PVAc) synthesized from vinyl acetate was prepared by solvent cast process. NR KMnO4 oxidized latex, functionalizing NR. PVAc blends with varying ratios of NR and oxidized NR (ONR) were also made. Then, tensile testing, SEM, and FTIR were used to characterize the blends and composites along with their constituent parts analyses.

Findings: By this study, a novel eco-friendly nanocomposite based on natural rubber, nanocellulose and vinyl acetate have been developed. FTIR analysis confirmed the functionalization of NR. FTIR analysis also indicated some chemical interactions between PVAc and ONR matrices. According to SEM analysis, the nanocellulose was uniformly distributed throughout the matrices. According to the tensile test findings, incorporation of 5 wt% nanocellulose into ONR/PVAc blend improved the composite's tensile strength considerably.

Practical implications: The developed composite can be promising alternative to non-biodegradable synthetic materials because of bio-based, flexibility and improved mechanical properties. The developed material can be used to prepare mono use plastic articles such as plate, cup etc.

Originality value: This study can be applied to develop similar eco-friendly composites based on other agricultural wastes such as rice straw, wheat straw etc. Use of oxidized NR as compatibilizer in NR/PVAc/NC composites as well as an optimized compositions of nanocellulose should be necessary to find out for further development of the composites.

Keywords: blends, composites, compatibility, morphology, mechanical properties.
