The Effect of Freezing Rate on Properties of PVA Hydrogels Prepared by Cyclic Freezing/Thawing
Original language description
Optical, mechanical, and transport properties of hydrogels are crucial for their potential applications. One of the widely used polymers for preparation of hydrogels for biomedical applications is polyvinyl alcohol (PVA). PVA hydrogels can be formed via physical crosslinking (e.g. by cyclic freezing/thawing of aqueous PVA solutions) or with a chemical cross linker (e.g. glutaraldehyd). Physically crosslinked PVA hydrogels are more suitable candidates for biomedical applications because they do not contain residues of potentially hazardous substances (e.g. crosslinkers and others). Properties of a physically crosslinked PVA hydrogel can be influenced by the concentration of PVA and by the temperature of freezing that defines the freezing rate. This work therefore focuses on the study of changes in the optical and mechanical properties caused by the modification of the preparation process of PVA hydrogels. The microstructure was also observed and the connection between the change in optical and mechanic
