A new family of poly(NIPAAm-co-2-acrylamido-2-methyl-1-propanesulfonic acid) [P(NIPAAm-co-AMPSA)] hydrogels was synthesized by incorporating negative charged AMPSA to the backbone of the PNIPAAm-based hydrogel. The effect of polyelectrolyte (i.e., PAMPSA) on the thermosensitive property of PNIPAAm hydrogels was investigated. It was found

It has been a common belief that articular cartilage tissue cannot regenerate in vivo. Recently, however, we have found that spontaneous hyaline cartilage regeneration can be induced in vivo by implanting a synthetic double-network (DN) hydrogel, which is composed of

The radiowave dielectric properties of aqueous solutions of thermosensitive copolymers, consisting of poly(2-acrylamido-2-methylpropanesulfonate) [PAMPS] and poly(N-isopropylacrylamide) [PNIPAAM] with different block lengths, have been investigated over a broad temperature and frequency range. These copolymers PAMPS(n)-b-PNIPAAM(m) form temperature responsive aggregates (micelles) that

The friction between two polyelectrolyte gels carrying the same or opposite sign of charges has been investigated using a rheometer. It is found that the friction was strongly dependent on the interfacial interaction between two gel surfaces. In the repulsive

Articles

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.
