  • Publication number: 20230051952
    Abstract: A plastic substrate includes: a plastic support member having light transmittance; and a first organic-inorganic hybrid layer on the plastic support member. The first organic-inorganic hybrid layer includes: a first organic-inorganic hybrid matrix; and ions implanted into the first organic-inorganic hybrid matrix at a side opposite to a side adjacent the plastic support member. An amount of the ions per unit area is in a range from about 2×1013/cm2 to about 2×1014/cm2.

  • Patent number: 10806704
    Abstract: Multilayer thin emulsion films are disclosed. Also disclosed are methods for preparing the multilayer thin emulsion films. According to the methods, an amphiphilic block polymer is used as a surfactant to form a polymer thin film at the oil/water interface, ionic lecithin is used as an auxiliary surfactant to prepare physically stable ionic oil-in-water nanoemulsions, and a layer-by-layer assembly technique is used to alternately laminate polymer thin films and nanoemulsion layers. The multilayer thin emulsion films enable slow release of active substances in specific temperature ranges and are structurally biocompatible while possessing improved capture efficiency and physically stable membrane structures. Spinodal decomposition of the multilayer thin emulsion films is induced by heating, allowing release of oils and active substances loaded into the nanoemulsions.
