    • In some embodiments, the present disclosure pertains to gas barrier composites that include a polymer matrix and graphene nanoribbons dispersed in the polymer matrix. The polymer matrix can include a phase-separated block copolymer with a hard phase domain and a soft phase domain. Likewise, the functionalized graphene nanoribbons can include edge- functionalized graphene nanoribbons with concentrations that range from about 0.1% by weight to about 5% by weight of the gas barrier composites. In some embodiments, the present disclosure pertains to methods of making gas barrier composites by dispersing graphene nanoribbons in a polymer matrix. In some embodiments, the dispersing lowers the permeability of a gas through the gas barrier composite and causes phase separation of block copolymers in the polymer matrix. In some embodiments, the dispersion of graphene nanoribbons in the polymer matrix lowers the gas effective diffusivity of the gas barrier composite by three orders of magnitude.
    • 在一些实施例中,本公开涉及气体阻隔复合材料,其包括聚合物基质和分散在聚合物基质中的石墨烯纳米带。 聚合物基质可以包括具有硬相域和软相域的相分离嵌段共聚物。 同样地,官能化石墨烯纳米带可以包括边缘官能化石墨烯纳米带,其浓度范围为阻气复合材料的约0.1重量%至约5重量%。 在一些实施方案中,本公开涉及通过将石墨烯纳米带分散在聚合物基质中来制造气体阻隔复合材料的方法。 在一些实施方案中,分散降低气体通过阻气复合材料的渗透性并引起聚合物基体中嵌段共聚物的相分离。 在一些实施方案中,石墨烯纳米带在聚合物基质中的分散体将气体阻隔复合材料的气体有效扩散率降低三个数量级。
