Description

一种石墨烯复合材料
技术领域
本发明属于石墨烯材料技术领域，涉及一种石墨烯复合材料。
背景技术
石墨烯是导电和导热性能俱佳的材料，其电阻率约为10-6Ω·cm，为目前电阻率最小的材料；其导热系数高达3000W/m·K，高于碳纳米管和金刚石；常温下其电子迁移率超过15000cm2/V·s，也高于纳米碳管或硅晶体。由于电阻率极低，电子迁移速度极快，因此石墨烯被期待开发成为新一代电子元件或晶体管。
虽然石墨烯所具有的优异物理性质使其可以广泛应用于各种装置中以提高装置的导电、导热或强度等特性，然而石墨烯分子结构的平面性相对较差，物化性质也随之受到一定的影响，因此如何提高石墨烯复合材料的物化性质，仍是亟待解决的难题。
发明内容
针对上述情况，本发明的目的在于提供一种石墨烯复合材料。
为了实现上述目的，本发明采用以下技术方案：
一种石墨烯复合材料，其包含以重量份计的下列组分：石墨烯50～80份、丁腈橡胶20～40份、热塑性聚氨酯5～10份、纳米氧化钙1～5份和脲醛树脂40～70份。
优选的，所述石墨烯复合材料包含以重量份计的下列组分：石墨烯60～70份、丁腈橡胶25～35份、热塑性聚氨酯6～9份、纳米氧化钙2～4份和脲醛树脂50～60份。
更优选的，所述石墨烯复合材料包含以重量份计的下列组分：石墨烯65份、丁腈橡胶30份、热塑性聚氨酯7份、纳米氧化钙3份和脲醛树脂55份。
优选的，在上述石墨烯复合材料中，所述石墨烯通过化学气相沉积法、机械剥离法、化学剥离法或化学合成法制得。
优选的，在上述石墨烯复合材料中，所述丁腈橡胶中丙烯腈的摩尔含量为50～70％。
优选的，在上述石墨烯复合材料中，所述热塑性聚氨酯的玻璃化温度为100～105℃。
优选的，在上述石墨烯复合材料中，所述纳米氧化钙的粒径为100～200nm。
与现有技术相比，采用上述技术方案的本发明具有以下优点：本发明通过将石墨烯与丁腈橡胶、脲醛树脂等材料复配，使得石墨烯材料的物化性质得到强化，成功制得了石墨烯复合材料，极具市场前景。
