Abstract
Natural materials-based bioadhesives offer reliable and sustainable substitutes for synthetic adhesives due to their biocompatibility and sustainability. Water absorption properties in bioadhesives play a crucial role in determining their performance, particularly in biomedical, dental, and wood applications. The present review focuses on the chemistry and mechanisms beneath water absorption in bioadhesives, emphasizing the significant factors that impact this characteristic, including polymer structure, hydrophilic functional groups, cross-linked networks, and crystallinity. Water adsorption is also highly impacted by the presence of fillers and additives, as well as by environmental factors including pH, humidity, and temperature. In our study we explore how molecular weight, cross-linking density, and hydrophilic and hydrophobic functional groups affect the adhesive properties. Furthermore, the mechanisms of water-bioadhesive interaction, such as capillary action, diffusion, and swelling, are described. Through comprehension of the complex connection between polymer composition and water interaction, this review offers valuable perspectives for enhancing the functionality and design of bioadhesives for a range of uses. Additionally, the review addresses the challenges posed by high water absorption in carbohydrate- and protein-based adhesives, proposing strategies for enhancing their water resistance to expand their use in fields like wood bonding and biomedical applications.
