A hydrogel is a three-dimensional crosslinked network polymer containing an excessive amount of water. Hydrogels contain excess water and have various properties such as impact absorption, transparency, stimulus responsiveness, biocompatibility, and biodegradability, which are difficult to realize in solid materials such as metals and ceramics. Recently, the use of adhesives and sealants for hemostasis in the organs of the human body, which is mostly covered with mucous membranes, is continuously required. Natural polymers are suitable material for tissue-adhesive and biodegradable hydrogels, but they are disadvantageous in that they are biocompatible but have weak mechanical properties. In this study, we tried to improve the physical properties of hydrogels prepared from natural polymers. Also, hydrogels with flexible and adhesive properties were prepared and their adhesive behavior was studied. |
