摘要

摘要本文对碳纳米管(CNTs)在水性胶凝材料中的分散过程进行了综述。CNTs在水体系中的分散主要有高剪切乳化、超声处理、共价改性和非共价改性。评价了各种因素对CNTs分散性能的影响,分析了CNTs分散工艺的优缺点,以及CNTs在水性材料中的分散机理。介绍了几种新技术,包括电弧热激励法和电磁场感应法等。此外,还详细介绍了碳纳米管在胶凝碱孔溶液中进一步分散所面临的挑战和改进手段。并对碳纳米管在胶凝材料中的直接分散过程(原位生长过程)进行了深入的讨论。

Dispersion of carbon nanotubes in aqueous cementitious materials: A review
Abstract In this review, the research reports on the dispersion processes of carbon nanotubes (CNTs) in aqueous cementitious materials are intensively introduced and summarized. The main processes for the CNTs dispersion in aqueous systems include high shear emulsification, ultrasonic treatment, covalent modification, and non-covalent modification. The influences of various factors on the dispersity of CNTs are evaluated, and the pros and cons of dispersion processes of CNTs are analyzed, along with the dispersion mechanism of CNTs in aqueous materials. Several novel techniques are also introduced, including arc thermal excitation and electromagnetic field-induced method, etc. In addition, the challenges when CNTs dispersion are further involved in cementitious alkali pore solution and the improvement means are also described in detail. And, the direct dispersion process (in situ growth process) of CNTs in cementitious materials has also been discussed in depth.
