| 摘 要： | 通过正交实验法研究了溶液插层-流延成膜法制备聚乙烯醇/蒙脱石纳米复合材料中制备工艺条件对复合材料结构的影响,确定了最佳的制备方法。对复合材料进行了TEM表征,结果表明:蒙脱石片层均匀的剥离分散在PVA基体中,蒙脱石含量不高于7.5wt%时,形成了剥离型的纳米复合材料;高于10wt%时,形成了剥离型和插层型共存的纳米复合结构。

| Abstract: | Orthogonal experiments were carried out to study the effects of the preparation processing conditions on the structure of Poly (vinyl alcohol)/montmorillonite nanocomposites, which were prepared by means of solution intercalation-casting film method, and confirmed the optimum preparation method. It made a characterization of PVA/MMT nanocomposites by means of TEM, the results showed that the montmorillonite layers exfoliate and disperse in the PVA matrix. Exfoliated nano-structures are formed when the addition of MMT is no more than 7.5wt%, and the coexistence of intercalated and exfoliated nanostructures are fonned when the addition of MMT is more than 10wt% . |
