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