摘要

摘要以多壁碳纳米管为基材，通过自由基聚合途径，将氧化后的碳纳米管与马来酸酐和α-壬烯单体反应，在温和条件下声化学合成了混凝土增强用添加剂。采用Fe-Co/Al2O3催化剂催化化学气相沉积法制备了作为主要补强部分的纳米管。利用透射电子显微镜、扫描电子显微镜、傅里叶变换红外光谱、x射线衍射和拉曼光谱技术对所得纳米复合材料进行了表征。上述方法的结果表明合成工艺是成功的。力学试验结果表明，所制备的纳米结构具有52.2%的增强潜力，是一种较好的混凝土增强材料。

Sonochemically synthesized MWCNT-maleic anhydride-nonene-1 additive material with concrete strengthening potential

ABSTRACT The additive for concrete strengthening purposes based on the multiwalled carbon nanotubes was sonochemically synthesised under mild conditions through a radical polymerisation route by the reaction of oxidised nanotubes with maleic anhydride and α-nonene monomers. The Catalytic Chemical Vapour Deposition over the Fe-Co/Al2O3 catalyst was the method for the synthesis of the nanotubes used as the main reinforcement part. The resulting nanocomposite was characterised using Transmission electron microscopy, Scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy techniques. The results from the above-mentioned methods revealed the success of the synthesis process. The mechanical testing showed that the obtained nanostructure is suitable additive material for concrete strengthening purposes with about 52.2% strengthening potential.

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
