    • The nanoscopic dimensions of polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) materials ranges from 0.7 nm to 5.0 nm and enables the thermomechanical and physical properties of polymeric materials to be improved by providing nanoscopic reinforcement of polymer chains at a length scale that is not possible by physically smaller aromatic chemical systems or larger fillers and fibers. A simple and cost effective method for incorporating POSS/POS nanoreinforcements onto polymers via the reactive grafting of suitably functionalized POSS/POS entities with polymeric systems amenable to such processes is described. The method teaches that the resulting POSS-grafted-polymers are particularly well suited for alloying agents by nongrafted POSS entitles such as molecular silicas. The successful alloying of POSS-polymers is aided because their interfacial tensions are reduced relative to non-POSS containing systems.
    • 多面体低聚倍半硅氧烷(POSS)和多面体低聚硅酸盐(POS)材料的纳米尺寸范围为0.7nm至5.0nm,并且通过以长度尺度提供聚合物链的纳米级增强,可以改善聚合物材料的热机械和物理性能, 通过物理上较小的芳族化学体系或较大的填料和纤维是不可能的。 描述了通过适当功能化的POSS / POS实体与适合于这种方法的聚合物体系的反应性接枝将POSS / POS纳米增强剂结合到聚合物上的简单且成本有效的方法。 该方法教导得到的POSS接枝聚合物特别适用于通过非接枝POSS权利如分子二氧化硅的合金化剂。 有助于POSS聚合物的成功合金化,因为它们的界面张力相对于不含POSS的体系而降低。

    • A method of using olefin containing nanostructured chemicals and silanol containing nanostructured chemicals as high temperature resins is described. Vinyl containing nanostructured chemicals are particularity effective in thermosets as they control the motions of polymer chains, and segments, at the molecular level. Silanol containing nanostructured chemicals are particularity effective in thermosets containing polar groups as the silanol can enhance the reactivity of these groups. Because of their tailorable compatibility with fluorinated polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending and polymerization processes. The incorporation of a nanostructured chemical into a polymer favorably impacts a multitude of polymer physical properties. Properties most favorably improved are heat distortion and flammability characteristics, permeability, optical properties, texture, feel and durability. Other properties improved include time dependent mechanical and thermal properties such as creep, compression set, shrinkage, modulus, and hardness. In addition to mechanical properties, other physical properties are favorably improved, including lower thermal conductivity, and gas oxygen permeability. These improved properties may be useful in a number of applications, including composite materials, foams, cosmetics, and durable coatings.
