Elastomers and gels can be formed by interpenetrating two polymer networks on a molecular scale. This paper develops a theory to characterize the large deformation and damage of interpenetrating polymer networks. The theory integrates an interpenetrating network model with the network alteration theory. The interpenetration of one network stretches polymer chains in the other network and reduce...

interpenetrating polymer networks (ipn) were formed involving hydrophobic polybutyl acrylate (pba) and hydrophilic poly hydroxyethyl acrylate (phea). pba prepolymer was first formed in presence of ferric oxide nanoparticles (

Natural polymers such as proteins and polysaccharides though very useful exhibit a limitation in their reactivity and process ability. These shortcomings were overcome by chemical and physical alteration of natural polymers. Among various investigations, the interpenetrating polymer networks (IPNs) for hydro gels have attracted much attention. It is a combination of at least two polymer chains ...

Stimuli-responsive polymer hydrogels which are capable of responding to changes in their environment such as pH (1), osmotic strength (2), or temperature (3) have received growing attention in recent years for applications in a wide variety of areas including controlled drug delivery (4). Also, due to the size limitations imposed by the body’s natural defense mechanisms, such as the reticuloend...

A simple two-steps polymerization method was used to prepare a polyacrylamide hydrogel with a full interpenetrating network structure based on the sorption and porous properties of polyacrylamide superabsorbent. In conditions of 10 g acrylamide monomer, 0.04 g crosslinker for the first polymerization and the second polymerization, respectively, and the swelling ratio of 9, the hydrogel possesse...
