  The present invention relates to the field of sterilization of items that are sensitive to e.g. temperature, pH, positive or negative pressure, radiation or oxidation. More particularly, the invention concerns a method, the use of this method and an apparatus for sterilization or disinfection, comprising the steps of contacting one or more item or part of an item with a water-based fluid comprising at least one reductant, followed by the step of contacting with a gas having oxidative properties in a substantially water-free environment. According to the invention, items can be sterilized that are otherwise impaired by conventional sterilization procedures, such as laboratory items, medical items, dental items, military items, biological items, and food processing-related items.

  本发明涉及对温度、pH值、正压或负压、辐射或氧化等敏感的物品的灭菌领域。更具体地说，本发明涉及一种灭菌或消毒的方法、该方法的用途和设备，包括以下步骤：将一个或多个物品或物品的一部分与含有至少一种还原剂的水基流体接触，然后在基本上无水的环境中与具有氧化特性的气体接触。根据本发明，可以对常规消毒程序无法消毒的物品进行消毒，例如实验室物品、医疗物品、牙科物品、军事物品、生物物品和食品加工相关物品。

  The present invention is directed to a method for treating a surface of a filled microporous membrane. The microporous membrane includes a polyolefinic matrix, inorganic filler distributed throughout the matrix, and a network of interconnecting pores throughout the membrane. The method includes sequentially (1) contacting the membrane with a first treatment composition comprising an epoxy-silane which is in intimate contact with the inorganic filler; (2) subjecting the membrane of (1) to conditions sufficient to effect a first reaction between the inorganic filler and the silane groups of the epoxy-silane compound; (3) contacting the membrane of (2) with a second treatment composition comprising polyalkylene polyamine, an amine functional polysaccharide and/or an amino silane; and (4) subjecting the membrane of (3) to conditions sufficient to effect a second reaction. Treated membranes also are provided.

  本发明涉及一种处理填充微孔膜表面的方法。微孔膜包括聚烯烃基体、分布在基体各处的无机填料以及遍布整个膜的相互连接的孔网。该方法包括依次(1)将膜与第一处理组合物接触，该组合物包括与无机填料亲密接触的环氧硅烷；(2)将(1)的膜置于足以使无机填料和环氧硅烷化合物的硅烷基团之间发生第一反应的条件下；(3) 将(2)中的膜与第二种处理组合物接触，该组合物包括聚亚烷基多胺、胺功能多糖和/或氨基硅烷；以及 (4) 将(3)中的膜置于足以发生第二种反应的条件下。还提供了经过处理的膜。
