水凝胶合成

Hydrogels are a versatile class of cross-linked polymers, produced through relatively simple procedures using generally inexpensive materials. They are commonly used for liquid absorbents, sensors, consumer products and drug delivery. Hydrogels can be formed from solution, with an initiator making monomerie agents reactive to form a polymer backbone. A crosslinking species then binds the polymer chains together. An important aspect of these materials is that in the presence of water they swell. But this response can be tuned further to enhan
