摘要 利用冰模板法制备一种具有高孔隙率的碳纳米管强化氧化铝(CNTs-Al2O3)多孔陶瓷复合材料。采用SEM,XRD及Raman对样品进行表征,研究碳纳米管(CNTs)含量对复合材料微观形貌、性能的影响。结果表明:随着CNTs含量的增大,复合材料的体积密度、孔隙率和抗压强度均发生改变;添加适量的CNTs能促进陶瓷孔壁烧结致密度,提高材料的抗压强度;但加入过量CNTs会导致CNTs团聚,嵌于陶瓷内壁形成微孔,反而降低了材料致密度与抗压强度;当CNTs含量达2.0%(质量分数)时,多孔陶瓷的抗压强度达到最大值4.52MPa,相对纯Al2O3多孔陶瓷提高了66%。

Abstract:Carbon nanotubes-alumina (CNTs-Al2O3) porous composite with high porosity and excellent compressive strength was prepared by ice-template technique. Effects of different CNT concentrations on microstructure and properties of the composite were investigated intensively by SEM, XRD and Raman. The results show that the bulk density, porosity and compressive strength of the composite will change with the increase of CNT content. Adding appropriate amount of CNTs will be able to increase the density of ceramic lamellae and enhance the compressive strength of the composite. However, excessive CNTs adversely will decrease the density and compressive strength of material due to the micro pores caused by CNT agglomerations anchored on the internal wall of porous ceramic. The composite reaches a maximum compressive strength of 4.52MPa when additive amount of CNTs at 2.0%(mass fraction), which increases by 66% comparing to pure Al2O3 porous ceramic.
