Abstract
This study is mainly focused on explaining the effect of the concentration of Molsive clay on the adhesive performance of the synthesized hydrogel. Adhesive hydrogels have attracted significant interest for various applications such as tissue engineering, wound dressing, crack propagations, and solid surface repairing. Physical forces such as electrostatic interaction and hydrogen bonding are used to keep the polymer chains in the three-dimensional structure. The adhering behavior of hydrogels strongly depends on the interactions between polymer chains and surfaces. Analysis of rheological data showed an increase in adhesion strength order 4.580 > 3.885 > 3.824 kPa with the addition of 0.07, 0.05, and 0.025 g Molsive clay in hydrogels compared to neat sample having 0.286 kPa adhesion strength. Temperature effect on the adhesion performance was elaborated and it was found that the prepared hydrogels slightly decrease the adhesion strength at high temperature but can be utilized for adhesion. For practical application, the hydrogels were used as a binder for solid surfaces made of plastic, wood, glass, cloth, steel, and ceramics. The materials were found effective towards all surfaces but more towards wood surfaces and ceramics. The underwater adhesion also confirms the suitability and practical adaptability of the prepared hydrogels as a binder for different surfaces in the future.
