Hydrogel

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: The hydrogel is a tri-polymer network that may soak up body fluids in a biological setting but is not soluble in water. Water can cause the hydrogel to structurally bulge and it can hold a lot of water. Such a polymer network is produced by operating a merging of physical and chemical crosslinking techniques, besides ionic crosslinking ...
