A membrane or laminate (10) consisting essentially of microporous polymerized material (12) consisting essentially of a precursor material which forms a homogenous solution with a liquid vehicle and is 1) rapidly polymerizable under ultraviolet or electron beam irradiation to a polymerized material, which is insoluble and nondispersible in the liquid vehicle, and 2) selected from the group consisting of organic monomers, organic oligomers, and mixtures thereof which are soluble in the liquid vehicle, the liquid vehicle being inert relative to the precursor material and optionally a support material (14) laminated directly to the microporous material. The precursor microporous material may include a hydrophobic monomer. The instant invention further provides a method for manufacturing the fluid permeable microporous membrane laminate (10) including the steps of mixing the precursor material into the liquid vehicle, forming the composition into a thin liquid layer, applying a support material (14) into intimate contact with the liquid layer, exposing the combined liquid layer and support material (14) to ultraviolet or electron beam irradiation to finally cure the liquid layer and form a laminate with the support material 14, and removing the liquid vehicle from the laminate (10).
一种主要由微孔聚合材料(12)构成的膜或层压材料(10),该材料主要由前体材料构成,前体材料与液体载体形成均质溶液,并且 1) 在紫外线或电子束照射下可快速聚合成聚合材料、2) 选自有机单体、有机低聚物及其混合物组成的组,可溶于液体载体,液体载体相对于前驱体材料是惰性的,也可选择直接与微孔材料层压的支撑材料 (14)。前体微孔材料可包括疏
水单体。本发明进一步提供了一种制造流体可渗透微孔膜层压板(10)的方法,包括以下步骤:将前体材料与液体载体混合,将组合物形成薄液层,将支撑材料(14)与液层紧密接触,将组合液层和支撑材料(14)暴露于紫外线或电子束照射下以最终固化液层并与支撑材料 14 形成层压板,以及从层压板(10)上去除液体载体。
