Latest Patents

One of Hu's latest inventions is a transparent gas barrier composite film and its preparation method. This innovative film is created by blending polyvinyl alcohol, graphene oxide, and a crosslinking agent through a series of processes including blending, crosslinking, film casting, and isothermal crystallization. The resulting composite film boasts a weight ratio of graphene oxide to polyvinyl alcohol of 0.1 wt %. This unique structure allows for a crystallinity of polyvinyl alcohol exceeding 30%, a transmittance of over 85%, and an oxygen transmission rate of less than 0.005 cc/m/day.

Another significant patent is the method for fabricating a semicrystalline polymer/graphene oxide composite film. This invention features a first semicrystalline-typed polymer with a porous structure, combined with graphene oxide that has a layered structure. The innovative design allows for gas passage between adjacent layers, while the heat treatment process transforms part of the first semicrystalline polymer into a second semicrystalline polymer, effectively blocking gas flow and extending the path length of gas passage.
