  Graphene doped AZO thin films were prepared by sol-gel method with using metal salts and reduced grapheneoxide(rgo) as raw materials and using ethylene glycol dimethyl ether as solvent,though spin coating to form wet film,last thin film was obtained after annealing at 500 ℃.Respectively by means of X-ray diffraction (XRD), scanningelectron microscopy (SEM),transmission electron microscope(TEM),X-ray photoelectron spectroscopy (XPS) analysis, ultraviolet visible absorption spectroscopy (UV-Vis) and four-point prober tester for thin film materials of morphology, structure characterization.The experimental results show that, Al was doped into the crystal of ZnO,nanoparticlesZnO are uniformly distributed on the rgonanosheets.RGO doping led to destruction and reorganization of ZnO structure but nanoparticles ZnO still had ahexagonalwurtzite structure with a preferential orientation along(002)crystal plane at surface of rgo.And the square resistance of graphene doped AZO thin films has been improved significantly compare to pru AZO thin films(about from 55 k ohm/sq drop to 8 k ohm/sq).Preparation of graphene doped AZO thin films explore the feasible method for its application in the preparation of composite materials and the application of transparent conductive films.

超级隔热材料二氧化硅气凝胶被广泛用于各种航天器、飞行器的热防护中。添加遮光剂或纤维能大大改善其在高温下的隔热性能。本文中假设遮光剂颗粒为球形,掺杂纤维为无限长圆柱,通过计算遮光剂及纤维的辐射特性得到不同温度下最优掺杂粒径,并在复合材料等效热导率最小时得到不同温度下的最佳掺杂量。研究发现:遮光颗粒和纤维的最佳掺杂直径随温度增加而减小,掺杂量随温度增加而增加,研究的四种遮光剂(碳黑、SiC、ZrO2和
