(如图所示)化学家用的聚合物粘土：在N-异丙基丙烯酰胺的原位自由基聚合过程中，通过加入大量纳米分散的无机粘土，证明了聚合物水凝胶的高强度和高断裂能。通过改变粘土的用量，可以控制纳米复合材料(NC)的机械性能以及膨胀和透明度(见图；NC20比NC5含有更多的粘土)。
(Figure Presented) Polymer clay for chemists: High strengths and high fracture energies of polymeric hydrogels have been demonstrated by incorporating a substantial amount of nanodispersed inorganic clay during the in situ free-radical polymerization of N-isopropylacrylamide. By varying the amount of clay used, mechanical properties as well as the swelling and transparency of the nanocomposite (NC) could be controlled (see picture; NC20 contains more clay than NC5).
