摘要
提出了一种制备填充型导电复合材料的新方法。基于选择性激光烧结技术,快速制备了类蜂窝多孔石墨骨架坯体;对坯体进行浸渍、干燥、炭化处理后,获得了预制体;将预制体与酚醛树脂粉末复合在一起,获得了新型导电复合材料。研究结果表明,当蜂窝数量为18个时,Y型导电复合材料电导率达0.104 S·cm -1,抗弯强度达20.61 MPa。可通过不同的多孔石墨骨架结构和后处理工艺来调控填充型导电复合材料的力学和电学性能。
Abstract
A new method to fabricate the filled-type conductive composites is proposed. Based on the selective laser sintering technology, the honeycomb-like porous graphite skeleton body is fast fabricated. After the immersion, drying and carbonization treatments for the body, the preform is obtained. The new conductive composite is prepared with the combination of the preform and the phenolic resin powder. The research results show that, when the number of honeycombs is 18, the conductivity of Y-type conductive composites can approach 0.104 S·cm -1, while the bending strength is 20.61 MPa. The electrical and mechanical properties of the filled-type conductive composites can be adjusted and controlled with the different porous graphite skeleton structures and the different post-treatment processes.
