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.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"142 ","pages":"Article 104105"},"PeriodicalIF":3.2,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144665562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This adhesion is seen at a high rate in many patients after the surgical operation. It is especially observed in biological parts such as the abdominal cavity, thoracic cavity, and tendons. Due to the healing of the fibrous tissues in the wound after the surgery, this part causes adhesion in the surrounding tissues and organs, and patients may develop complications such as chronic pain, intestinal obstruction and functional obstruction of organs after adhesion, may require a repeat surgical operation, and is a serious problem that may cause infertility in women. Chronic pain, intestinal obstruction, and functional obstruction of organs may develop complications after adhesion. To prevent this situation, it is very important to develop barriers with higher biocompatibility, low cost, easily applicable, and synthesizable instead of existing anti-adhesive barriers. Potential candidates with these properties are thought to be polymers. Polymers offer many options for use as anti-adhesive barriers since they can be obtained from natural sources and synthetically. These options can be designed according to the characteristics of the anti-adhesive barriers desired to be synthesized. These polymers can be produced in a short time using very simple techniques in the forms of hydrogel, membrane, fiber, film, etc. In addition to these, these polymers synthesized as anti-adhesive membranes can act as simultaneous drug release and imaging agents in various combinations. In this article, medical and biological applications of anti-adhesive barriers with various formulations developed with different polymer types are mentioned.

Glulam consists of layers of low and medium-density wood bonded with specific adhesives, resulting in a material with superior mechanical properties and greater versatility. This study analyzed the performance of four low-density Amazonian species (<em>Jacaranda</em> sp., <em>Cedrela fissilis</em>, <em>Cordia goeldiana</em>, and <em>Simarouba amara</em>) in combination with different adhesive types (PVAc, EPI, PUR, and PU). Shear strength and accelerated delamination tests were conducted to evaluate the feasibility of these combinations for structural applications. The results indicated that EPI and PU adhesives excelled in shear strength, even surpassing the strength of solid wood in some species. However, performance varied by species, with <em>Cordia goeldiana</em> showing lower compatibility with PU. Delamination tests revealed that EPI and PVAc adhesives were more effective under external conditions, while PUR showed a higher tendency for delamination. It is concluded that the studied Amazonian species have significant potential for glulam production, provided that the appropriate adhesive is selected for each species.

For each adhesive, 20 samples were exposed to 4 h of tropical weather on five consecutive days (test group), and 20 samples were exposed to room temperature and dark room conditions for five consecutive days (control group). A T-peel test was conducted using a Universal Testing Machine and the samples were visually analyzed for mode of failure. Raman spectroscopic analysis was conducted with backscattering configuration.</div></div><div><h3>Results</h3><div>There were no significant differences in MFPSA peel bond strength between regular adhesive and hydrobond adhesives following five days of exposure to tropical weather. Within the tropical weather (test) group, hydrobond adhesive demonstrated similar peel bond strengths compared with the regular adhesive; p = 1.00 (Table 2). Within the room temperature and dark room conditions (control) group, hydrobond adhesive showed peel bond strengths significantly greater than the regular adhesive (p = 0.16). The mixed mode of failure involving both adhesive and cohesive failure was observed in 80 % of specimens.</div></div><div><h3>Conclusions</h3><div>The MFPSA peel bond strength was not affected by tropical weather conditions. Within the limitations of this in vitro study, the hydrobond adhesive demonstrated greater adhesive strength than the regular adhesive in room temperature and dark room conditions.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"142 ","pages":"Article 104095"},"PeriodicalIF":3.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
