Abstract
Sustainable and eco-friendly bio-based adhesives have gained increasing attention as promising alternatives to conventional industrial adhesives that rely on non-renewable resources. Among bio-based materials, cellulose has emerged as a promising candidate for adhesive applications owing to its abundance, excellent biodegradability, and renewability. However, the inherent hydrophilicity of cellulose significantly challenges its application in adhesive systems, resulting in poor bonding strength and water resistance. In this study, modified cellulose (MC) was synthesized via a simple surface modification, reducing hydrophilicity and introducing thermosetting functional groups onto the cellulose surface. The successful surface modification was confirmed by FT-IR, XPS, and solid-state ¹³C NMR analyses. To overcome the limitations of conventional cellulose-based adhesive systems, MC was utilized to develop a cellulose-based adhesive, in which the thermosetting functional groups on MC contributed to the formation of an enhanced crosslinking network. The resulting adhesive demonstrated superior bonding strength and water resistance compared to adhesive systems using neat cellulose. These findings present a simple and eco-friendly approach for the development of high-performance cellulose-based adhesives.
