Graphene oxide modified carbon/carbon composite material and preparation method thereof
The invention discloses a graphene oxide modified carbon/carbon composite material and a preparation method thereof. The method comprises the following steps: spraying a graphene oxide solution on the surface of a carbon fiber, and drying to obtain a single-layer graphene oxide preform; and the multiple single-layer graphene oxide preforms coated with the binder are stacked and then cured to obtain the multi-layer graphene oxide preforms. And carrying out carbonization treatment on the multilayer graphene oxide preform to obtain the graphene oxide modified carbon/carbon composite material. The carbon/carbon composite material with high electromagnetic shielding effectiveness (more than 40dB) is obtained by adopting the low-content graphene oxide, the cost is low, and the method is simple.
本发明公开了一种氧化石墨烯改性的碳/碳复合材料及其制备方法，所述方法包括如下步骤：将氧化石墨烯溶液喷涂在碳纤维表面后烘干获得单层氧化石墨烯预制体；将多个涂刷粘结剂的单层氧化石墨烯预制体叠加后固化获得多层氧化石墨烯预制体。将多层氧化石墨烯预制体进行碳化处理获得氧化石墨烯改性的碳/碳复合材料。本发明采用低含量的氧化石墨烯就科获得高电磁屏蔽效能(超过40dB)的碳/碳复合材料，成本低且方法简单。
