Aluminum molybdate ceramic filled polytetrafluoroethylene microwave dielectric composite material and preparation method thereof
The invention relates to the technical field of high-tech functional ceramics, in particular to an aluminum molybdate ceramic filled polytetrafluoroethylene microwave dielectric composite material and a preparation method thereof. The method comprises the following steps: carrying out surface modification on aluminum molybdate ceramic by adopting tridecafluorooctyltriethoxysilane to obtain modified aluminum molybdate ceramic, and sintering and compounding the modified aluminum molybdate ceramic and polytetrafluoroethylene to obtain the composite material. According to the method, the uniformity of aluminum molybdate ceramic particles in a polytetrafluoroethylene matrix can be effectively improved, the compactness of the composite material is promoted, and finally the performance is improved; the material is simple in preparation process, relatively low in cost and non-toxic and harmless to the environment; the composite material is high in density, free of abnormal growth of crystal grains, controllable in size and uniform in distribution; the composite material is low in dielectric constant and low in loss, and can be used as a substrate material in a microwave communication technology.
