摘要: A film of expanded poly(tetrafluoroethylene) abbreviated here as ePTFE shows no penneabilities in aqueous solutions because its hydrophobicity. However, the grafted with acrylic acid (ePTFE-g-PAA) by combined use oxygen plasma treatment and photografting gains excellent permeabilities some hydrophilic solutes maintaining considerably high mechanical strength. In addition, permeation insulin through ePTFE-g-PAA can be controlled pH change medium. Using enzymatic reaction glucose oxidase glucose, we have ePTFE-g-PAAfilm.
