    摘要： Embodiments of the present disclosure provide a method of modifying a surface of a film with an inverse miniemulsion, the method comprising: preparing an inverse miniemulsion loaded with a precursor, and then configuring an alkaline miniemulsion, and finally preparing an oxide nanocrystal surface-modified film by a solvothermal process. Embodiments of the present disclosure drive an oxide nanocrystal precursor preloaded in the inverse miniemulsion to migrate to the surface of the film during a solvent thermal treatment by utilizing a pH-responsive polymer that changes the nature of the polymer in the presence of a change in pH, resulting in the formation of the oxide nanocrystal modification on the film surface. The functional film materials modified by the embodiments of the present disclosure have potential applications in the fields of semiconductor, photosensitivity and photoluminescence.

    摘要： A process for chemically modifying a polymeric part in order to impart antistatic properties thereto or to improve these properties, comprising the following steps: a step of reacting a polymeric part comprising at least one polymer comprising, as reactive groups, amine groups and/or hydroxyl groups, with a functional compound, also called first compound, comprising at least one isocyanate group and at least one heterocyclic type polymerisable group, the isocyanate groups covalently reacting with all or part of the amine groups and/or hydroxyl groups of the polymer(s), whereby this results in a polymeric part that is covalently bonded to residues of the functional compound; from the heterocyclic type polymerisable groups of the residues of the functional compound, a step of polymerising a second compound comprising at least one heterocyclic type polymerisable group in the presence of a metal complex, the reaction step and the polymerisation step being carried out in the presence of at least one supercritical fluid.
