采用原位自由基聚合法合成了具有独特粘土网络形态的疏水聚(2-甲氧基丙烯酸乙酯)和亲水性无机粘土组成的柔软透明的聚合物-粘土纳米复合材料(见图)。纳米复合材料首次表现出异常的颈缩行为，伴随着极大的可逆伸长率(1000-3000%)和良好的光学透明度，无论粘土含量(1-30wt%)如何。
Soft and transparent polymer-clay nanocomposites (see figure), consisting of hydrophobic poly(2-methoxyethyl-acrylate) and hydrophilic inorganic clay, with a unique clay-network morphology have been synthesized by in situ free-radical polymerization. The nanocomposites exhibit the first observation of abnormal necking behavior accompanied by extremely large reversible elongation (1000-3000%) and excellent optical transparency, regardless of the clay content (1-30 wt %).
