LAYER SILICATE NANOCOMPOSITES OF POLYMER HYDROGELS AND THEIR USE IN TISSUE EXPANDERS

摘要

The invention relates to nanocomposites comprising of (i) hydrogels synthetized by copolymerization of N-isopropylacrylamide and/or acrylamide and/or acrylic acid monomers and of (ii) layer silicates, and to the process for preparing them. The invention covers osmotically active hydrogel expanders containing said nano-composites, suitable for tissue expansion and the use of said materials for obtaining live skin.
