摘　　要：石墨烯材料在被发现后,其良好的力学性能、导电导热性、阻隔性以及易获得性能使其得到快速的推广使用,将石墨烯切割成一定宽度的长条带状石墨烯纳米带后保留了这些优点,并且在此基础上衍生出其他优异性能。本研究主要介绍了石墨烯纳米带的常见制备方法:超声化学法、刻蚀法、有机合成法、化学气相沉淀法和切割碳纳米管法。以及关于石墨烯纳米带负载于热塑性聚氨酯等基材上后,通过氧气透过率的降低证实两种材料的结合使其阻隔性能充分发挥、相互补充的相关应用。After the discovery of graphene materials,Its good mechanical properties,electrical and thermal conductivity,barrier properties and easy availability make it widely used.These advantages are retained after cutting graphene into strip graphene nanobelts with a certain width,And on this basis,other excellent properties are derived.This research mainly introduces the common preparation methods of graphene nanobelts:Ultrasonic chemical method,Etching,organic synthesis,chemical vapor deposition and cutting carbon nanotubes.And the related application that graphene nanobelts are loaded on thermoplastic polyurethane and other substrates,and the combination of the two materials is confirmed by the OTR,so that their barrier properties can be fully exerted and complemented each other.
