Abstract: The present invention relates to a polymer-ceramic hybrid film and a method for manufacturing same. The polymer-ceramic hybrid material according to the present invention, which is an elastic polymer-ceramic hybrid film, can maintain a film form for a long time while realizing excellent elasticity and mechanical properties at the same time, and thus can be applied as a medical material such as a patch. Also, a hydrogel used in the manufacturing process of the film can be very usefully utilized as a material for 3D printing. The mechanical strength and elasticity of the polymer-ceramic hybrid film according to the present invention can be improved by varying the arrangement of ceramic particles within the hybrid material by varying the processing process of a hybrid solution.

Abstract: Disclosed is a method for chemically modifying the surface of polytetrafluoroethylene materials, which allows biocompatibility of the materials to be improved. The method comprises the steps of: mixing a hydrogen compound, such as sodium hydroborate, with a cyclic compound, such as anthraquinone or derivatives thereof, in an organic solvent, such as dichloromethane, so as to produce a reactant solution; adding polytetrafluoroethylene materials, such as ePTFE artificial blood vessels, PTFE films or porous PTFE membranes, to the reactant solution; applying heat or ultraviolet energy to the mixture containing the polytetrafluoroethylene materials, so as to remove fluorine from the surface of the polytetrafluoroethylene materials by electron exchange reaction; removing the remaining reactants from the polytetrafluoroethylene materials; and drying the polytetrafluoroethylene materials.
