Effect of gas foaming and porosigen techniques on the properties of superporous hydrogels

Hydrogels is a type of hydrophilic polymers which exist in three dimension network that absorb significant amount of water. However, most of the dried hydrogels take long time to be swollen, which limits their applications. In order to overcome this problem, superporous hydrogels (SPHs) which are no...
