5. Cellulose-reinforced poly(ethylene

Author

Anoop, Singh, Sanjeev, Saini, Narinder, Singh, Navneet, Kaur, and Doo Ok, Jang

Abstract

Cellulose, a bio-derived polymer, is widely used in food packaging, dye removal, coatings, and solid-supported catalysis. Heterogeneous catalysts play a critical role in environmental remediation. In this context, the demand for green and cost-effective catalysts has rapidly increased. In this study, cellulose was extracted from rice straw, and a highly active solid-supported catalytic model was developed. First, cellulose was conjugated with poly(ethylene
