Critical assessment of the thermal stability and degradation of chemically functionalized nanocellulose-based polymer nanocomposites

Nanotechnology Reviews, Journal Year: 2024, Volume and Issue: 13(1)

Published: Jan. 1, 2024

Abstract In the last century, global awareness of environmental repercussions associated with petroleum-based polymer composites has surged. This realization urged extensive scientific research directed towards plant-based biomass, particularly nanocellulose, as a reinforcing element in matrices. Global market value nanocellulose is expected to increase considerably by 2025, forecast USD 783 million. Despite nanocellulose’s performance benefits, its poor compatibility hydrophobic matrices poses challenges, limiting thermal stability and impeding widespread commercialization at higher processing temperatures. To overcome these issues, chemical modification or functionalization emerges promising solution enhance nanocellulose-based nanocomposites’ stability. The abundance hydroxyl groups on enables specific modifications, such grafting functional molecules forming covalent/ionic bonds matrix. aim this study validate that integrating chemically functionalized into various matrices, including thermoset, thermoplastic, bio-polymer, enhances resulting nanocomposites, supported thermogravimetric analysis (TGA). also explores six additional factors influencing TGA providing comprehensive understanding elements impacting properties materials.
