Recently, applications of hyaluronic acid (HA) as a biomaterial were investigated. However, the weak structure of HA gel and the effects of using cross‐linker raised concerns during in vivo resolution. In this study, we investigated the method to solve these two problems using physical cross‐linking and compositing with poly(vinyl alcohol) (PVA). Various weight ratios of HA and PVA solutions were mixed, adjustment of pH to 1.8 using HCl then used to fabricate HA‐PVA cryo‐gel by freezing‐thawing. Young's modulus of the prepared gel rose with the increase of both HA and PVA concentrations or either one of them. We estimated that HA and PVA have exhibited these mechanical properties due to forming a double network. HA‐PVA gel showed kinetic friction force of approximately 10 times of PVA gel, while water contact angle and protein adsorption of HA‐PVA gels were remarkably decreased. The properties of the prepared gel suggest that it can be used for postoperative adhesion prevention applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
