我们继续研究的聚合物层状硅酸盐纳米复合材料的阻燃性降低的机制，产生了聚丙烯接枝马来酸酐和聚苯乙烯层状硅酸盐纳米复合材料使用蒙脱土和氟锂蒙脱石的结果。锥形量热法被用来测量的热释放速率和其他可燃性的纳米复合材料，在良好控制的燃烧条件下。通过透射电子显微镜和X射线衍射研究了聚合物-层状硅酸盐纳米复合材料和燃烧残留物。我们已经发现了降低可燃性的共同机制的证据。我们还发现，层状硅酸盐的类型，纳米分散，和加工降解的可燃性降低的影响。
Our continuing study of the mechanism of flammability reduction of polymer-layered-silicate nanocomposites has yielded results for polypropylene-graft-maleic anhydride and polystyrene-layered-silicate nanocomposites using montmorillonite and fluorohectorite. Cone calorimetry was used to measure the heat release rate and other flammability properties of the nanocomposites, under well-controlled combustion conditions. Both the polymer-layered-silicate nanocomposites and the combustion residues were studied by transmission electron microscopy and X-ray diffraction. We have found evidence for a common mechanism of flammability reduction. We also found that the type of layered silicate, nanodispersion, and processing degradation have an influence on the flammability reduction.
