Latest Patents

Nan Zhang's latest patents include a gas barrier material and a gas barrier laminate. The gas barrier material comprises a polycarboxylic acid polymer, containing 0.10 to 1.4% by weight of a monovalent metal element, at least 5.0% by weight of a polyvalent metal element, and 0.01 to 3.0% by weight of a nitrogen element per the total weight of nitrogen and carbon. This material exhibits excellent gas barrier properties, waterproof characteristics after bending, and an appealing surface appearance. The gas barrier laminate features an undercoating that includes a main resin, an isocyanate type curing agent, and an alkaline compound of a polyvalent metal. It also has a barrier layer formed from a polycarboxylic acid polymer, which creates ionic crosslinking due to the polyvalent metal among the carboxyl groups. This laminate demonstrates excellent gas barrier properties, retort resistance, and flexibility without interlayer peeling.
