中文摘要：

首先通过热溶剂法用钛酸钡（BaTiO3）对多壁碳纳米管（MWNT）进行改性，然后通过原位聚合法与亚甲基苯并二恶唑（PBO）进行复合，得到三元复合材料BaTiO3／MWNT／PBO，通过红外（FTIR）、XRD、TEM、热重等测试方法对样品进行表征，复合材料结构明确性能稳定，有望应用于结构型隐身材料领域．

英文摘要：

Firstly multi-walled carbon nano- tubes （MWNT） is modified by coating barium titanate BaTiO3 through the hydrothermal reaction method and then through in situ polymerization the ternary composite BaTiO3/MWNT/PBO which is tested via FTIR XRD TEM TGA and other methods is prepared and showed clear structures and stable perlbrmance. It is expected that the ternary composites may have a potential on microwave ab- sorbing material.
