    • A method for modifying a surface of a polymer such as a thermoplastic resin is provided, in which a supercritical fluid, especially carbon dioxide in a supercritical state is used as a solvent, and the polymer surface is further converted to have highly advanced function or high performance in a short period of time. In the method for modifying the polymer surface of the present invention, a solute is previously applied to the polymer surface. Accordingly, the solute can be permeated into the surface of the polymer swelled by the contact of the supercritical fluid. When this method is used, it is possible to permeate the solute into the polymer at a high concentration in a short period of time.
    • 提供了改性聚合物如热塑性树脂的表面的方法,其中超临界流体,特别是超临界状态的二氧化碳被用作溶剂,聚合物表面被进一步转化为具有高度的功能或高 在短时间内表现。 在本发明的聚合物表面改性方法中,预先将溶质施加到聚合物表面。 因此,溶质可以渗透到通过超临界流体的接触而膨胀的聚合物的表面中。 当使用该方法时,可以在短时间内以高浓度将溶质渗透到聚合物中。
