    • A method for oxidizing polymeric surfaces to render them hydrophilic and more amenable to wetting is disclosed. The method comprises reacting the surface of a hydrophobic polymer with a peracid, especially Caro's acid, under conditions effective to render the surface more hydrophilic. Although strong oxidants can easily carbonize or discolor the surface of organic polymers, polymers can be rendered more hydrophilic without these problems when process conditions are carefully controlled. Specifically, treatment of the polymer surface with a peracid such as Caro's acid requires judicious selection of oxidation temperature, acid concentration, and peroxide content to achieve reaction rates that provide the desired level of hydrophilicity without charring or otherwise damaging the polymer.
    • 公开了一种氧化聚合物表面使其亲水并且更易于润湿的方法。 该方法包括在有效使表面更亲水的条件下使疏水性聚合物的表面与过酸,特别是卡罗酸反应。 尽管强氧化剂可以容易地使有机聚合物的表面碳化或变色,但是当仔细控制工艺条件时,聚合物可以变得更亲水,而没有这些问题。 具体来说,用Caro酸等过酸处理聚合物表面需要明确地选择氧化温度,酸浓度和过氧化物含量,以达到提供所需水平的亲水性而不会发生炭化或以其他方式损害聚合物的反应速率。

    • Polymer surface modification method comprising the steps of first forming a surface of primary reactive end groups tethered to the polymer chain ends during fabrication of an article, and then modifying the reactive surface with bio-active molecules, hydrophilic and hydrophobic monomers, oligomers, or polymers to attain specific surface properties. Alternatively, a multifunctional coupling agent can be used to couple the primary reactive group to a second reactive group capable of reacting with a functional group associated with bio-active molecules, hydrophilic and hydrophobic monomers, oligomers, and polymers to attain specific surface properties. The invention involves bringing reactive endgroups to the surface with surface active spacer attached to the polymer chain end. The surface active spacer allows the migration and enrichment of reactive end groups to the surface during fabrication. The invention provides medical devices having a bio-interface with anti-thrombogenic properties, lubricity, selective adsorption, and antimicrobial properties.
