Swelling Properties of Chitosan/CMC/PEGDA based Semi-IPN Hydrogel

Hydrogels are three-dimensional and hydrophilic polymer which can be formed by cross-linking polymer chain and can swell but not dissolve in water. It can be applied to many fields, such as agriculture, hygiene products, wastewater treatment, and drug delivery system. Semi-interpenetrating polymer networks (semi-IPN) is a way of blending two polymers where only one is crosslinked in the presence of another to produce and additional non-covalent interaction between the two polymers.
