Spontaneous Formation of Characteristic Layered Morphologies in Porous Nanocomposites Prepared from Nanocomposite Hydrogels

Novel porous nanocomposites consisting of poly(N-isopropylacrylamide) and inorganic clay, prepared from nanocomposite hydrogels, spontaneously formed characteristic layered morphologies, with the most typical being a concentric three-layer morphology consisting of, successively, a fine-porous layer/a dense layer/a coarse-porous layer with polyhedral pores.
