Abstract

치유과정 중 이를 보호하기 위하여 예를 들어 상처, 화상등을 커버하기 위한 피부 커버 재료는 피부와 접착 접촉하는 점착성폴리머 복합체층(24), 및 이 폴리머르르 지지하는 수증기-투과성백층 (22,26)을 포함한다. 이 폴리머 복합체는 함께 혼합되었을때 공침하여 수-불용성 복합체를 형성하는 두 친수성 폴리머의 용액을 함께 혼합하는 것에 의하여 생산된다. 이러한 폴리머 쌍의 예로서는 폴리아크릴산 및 폴리에틸렌 옥사이드가 있다. 이 조립품은 수증기에 대하여 높은 장벽 특성을 갖고 고습도의 환경을 함유하는 밀봉 파우치(13)에 적절하게 포장된다.In order to protect it during the healing process, for example, a skin covering material for covering wounds, burns, etc. may be a tacky polymer composite layer 24 in adhesive contact with the skin, and a vapor-permeable white layer supporting the polymer 22, 26. It includes. This polymer complex is produced by mixing together a solution of two hydrophilic polymers that co-precipitate when mixed together to form a water-insoluble complex. Examples of such polymer pairs are polyacrylic acid and polyethylene oxide. This assembly is suitably packaged in a sealed pouch 13 having a high barrier property against water vapor and containing a high humidity environment.
