Abstract

Polyurethane hydrogels nanocomposites belong to a new class of hybrid biomaterials with unique swelling properties in comparison to unmodified hydrogels. These materials combine the typical properties of gels (elasticity and permeability) with the reinforcing properties of clay nanoparticles. Therefore, nanohydrogels might be applied in pharmacy for the controlled release and delivery of drugs and other biologically active agents, as well as in cosmetology as strong absorbents. We synthesized nanohydrogel polyurethanes with Cloisite® 30B organically modified clay nanoparticles of montmorillonite to obtain hybrid materials possessing great swelling properties. These materials were studied by XRD, DMA, and water absorption capacity measurements. The synthesis procedure yielded stable and homogeneous hydrogel materials. Addition of clay nanoparticles causes an increase in the absorptivity of water molecules in the polyurethane matrix.
