Abstract:
A process for preparing a nanocomposite, comprising combining:(A) at least 35% by weight of nanoscale particles of at least one inorganic compound, the particles having an average particle size of up to 200 nm and having surface groups present on the surface of the particles; (B) 10-60% by weight of at least one compound containing at least two functional groups capable of reacting and/or interacting with the surface groups present on the surface of the nanoscale particles of the component (A); and (C) 10-40% by weight of water and/or at least one organic solvent which has not more than one of the functional groups contained by the component (B); the above percentages being percentages of the sum of the components (A), (B), and (C), and (D) 0-10% by weight of additives, the percentage being a percentage of the weight of the nanocomposite, where the prepared nanocomposite contains at least 10% by weight of component (C), based on the sum of the components (A), (B), and (C).
