- •
Swelling ratio and water content were greatly reduced by swelling in osmotic solution.
- •
Crystallinity increased more significantly in PEG-based solution than in PBS solution.
- •
Compressive and storage modulus greatly increased after swelling in osmotic solution.
- •
Lower friction coefficient was obtained after swelling in osmotic solution.
- •
The hydrogels may show better material properties in vivo than in vitro evaluation.
