  • Transparent gas barrier composite film and its preparation method
    Patent number: 9701799
    Abstract: The invention provides a transparent gas barrier composite film and its preparation method. The transparent gas barrier composite film is formed by having polyvinyl alcohol, graphene oxide and a crosslinking agent undergo blending, crosslinking, film casting and isothermal crystallization processes where a weight ratio of graphene oxide to polyvinyl alcohol is 0.1 wt %, graphene oxide induces crystallization of polyvinyl alcohol to form a hybrid structure compose of polyvinyl alcohol crystals, graphene oxide and the crosslinking agent, crystallinity of polyvinyl alcohol is more than 30%, transmittance of the composite film is more than 85%, and the oxygen transmission rate of the composite film is less than 0.005 cc/m2/day.
    Type: Grant
    Filed: October 7, 2014
    Date of Patent: July 11, 2017
    Assignee: CHUNG YUAN CHRISTIAN UNIVERSITY

  • Silica-like membrane for separating gas and the method for forming the same
    Patent number: 9101885
    Abstract: The present invention discloses a silica-like membrane for separating gas, which is modified from poly(dimethylsiloxane) (PDMS) membrane by an atmospheric pressure high temperature plasma torch (APHTPT). Furthermore, the present invention of the separating gas silica-like membrane with an inorganic/organic interface structure which has both the gas flux of the organic membrane and also the gas selectivity of the inorganic membrane.
