The present invention includes a method for preparing a nanoparticle filled nanocomposite material, the method including the steps of providing a plurality of nanoparticles. attaching a first layer of organic ligand to the nanoparticle via a phosphate or phosphonate linkage, covalently attaching a second layer of matrix compatible polymer to said first layer of organic ligand to produce modified nanoparticles, providing a polymer matrix and dispersing the modified nanoparticles in the polymer matrix, wherein the dispersement of the modified nanoparticles into the polymer matrix results in a nanocomposite material, and wherein the modified nanoparticles are modified such that the first layer is proximal to the nanoparticle and the second layer is distal to the nanoparticle. Also within the scope of the invention are modified nanoparticles, alternative nanocomposite materials and methods of making the same.
本发明涉及一种制备纳米颗粒填充的纳米复合材料的方法,该方法包括以下步骤:提供多个纳米颗粒;通过
磷酸酯或
膦酸酯键将第一层有机
配体连接到纳米颗粒上;通过共价键将第二层与基质相容的聚合物连接到第一层有机
配体上,以产生修饰后的纳米颗粒;提供聚合物基质,并将修饰后的纳米颗粒分散在聚合物基质中,其中将修饰后的纳米颗粒分散到聚合物基质中,从而形成纳米复合材料,修饰后的纳米颗粒经过修饰,使得第一层靠近纳米颗粒,第二层远离纳米颗粒。本发明还涉及经过修饰的纳米颗粒、替代的纳米复合材料和制备方法。
