    摘要:

    为了探究三维石墨烯的红外消光性能,采用热化学沉积法制备了三维石墨烯粉体,通过电镜、拉曼光谱仪和X射线衍射仪表征了三维石墨烯粉体的形貌和结构特征,利用粉体综合特性仪测试了其流散性;利用烟幕箱试验测试了三维石墨烯的红外消光性能,并与复合石墨、碳纤维的消光性能进行了比较。结果表明:三维石墨烯的红外消光性能优异,在红外波段为3~5 μm和8~14 μm时,其平均质量消光系数分别约为1.32 m2·g-1和1.09 m2·g-1。与复合石墨和碳纤维相比,其在3~5 μm的平均质量消光系数分别提高了57%和132%,其在8~14 μm的平均质量消光系数分别提高了35%和102%,具有更优异的红外消光性能。

    Abstract:

    In order to explore the infrared extinction properties of three-dimensional graphene, three-dimensional (3D) graphene powders were prepared by thermochemical deposition method. The morphological and structural characteristics of the three-dimensional graphene powder were confirmed by electron microscopy and X-ray diffractometer, and the dispersion properties were tested by using a comprehensive powder characteristic tester. Then the infrared extinction properties of three-dimensional graphene were tested by using smoke chamber test, and compared with the extinction properties of composite graphite and carbon fiber under the same test conditions. The results show that the infrared extinction performance of three-dimensional graphene is excellent. The average mass extinction coefficients are about 1.32 m2·g-1 and 1.09 m2·g-1 in the infrared wavelength range of 3-5 μm and 8-14 μm, respectively. Compared with composite graphite and carbon fiber, the average mass extinction coefficients of 3-5 μm are improved by 57% and 132%, respectively. And the average mass extinction coefficients of 8-14 μm are improved by 35 % and 102 %, respectively. It can be seen that 3D graphene shows better infrared extinction ability.
