Hydrogels: An overview of its classifications, properties, and ...
2023年11月1日 · Hydrogel structure consists of a solid polymer network matrix called ‘mesh’ and bounded interstitial water or biological fluid. The matrix phase holds fluid and imparts elasticity to the hydrogel by expansion and contraction. The fluid phase makes hydrogel wet and soft by filling network interstitial sites.
