    • High-use temperature, lightweight polymer/inorganic nanocomposite materials are described having enhanced thermal stability and performance characteristics. These materials are made possible by new methods for synthesizing composite materials that enhance the thermal stability of the nanocomposite systems from 100-150 DEG C to over 450 DEG C. These materials and techniques for their formation are enabled at least in part by the use of polar organic phthalonitrile monomers and oligomers that can exfoliate layered phyllosilicates, such as smectite clays, in percentages greater than 10 % inorganic by weight. This approach offers a solvent-free direct melt intercalation technique that greatly reduces the cost of processing nanocomposites. Additionally, the use of unmodified phyllosillicates overcomes temperature limitations of prior art, which uses organically-modified layered silicates. The new technology provides hitherto unobtainable thermal stability and performance characteristics, and has numerous applications in the automotive, aerospace, electronic and marine industries.
    • 描述了具有增强的热稳定性和性能特征的高使用温度的轻质聚合物/无机纳米复合材料。 这些材料可以通过用于合成复合材料的新方法成为可能,这些复合材料增强了纳米复合材料体系的热稳定性,从100-150℃到超过450℃。这些材料和它们形成的技术至少部分地通过使用 极性有机邻苯二甲腈单体和可以以大于10重量%无机重量百分比的百分比剥落层状页硅酸盐如蒙脱石粘土的低聚物。 这种方法提供无溶剂的直接熔融插层技术,大大降低了加工纳米复合材料的成本。 此外,使用未经修饰的叶绿体可以克服使用有机改性的层状硅酸盐的现有技术的温度限制。 新技术提供了迄今为止无法获得的热稳定性和性能特征,并在汽车,航空航天,电子和海洋行业拥有众多应用。
