摘要：
As a new nano-material with superior performance, carbon nanotubes (CNTs) have been widely used to enhance the matrix materials. Due to the characteristic of easy agglomeration of CNTs, how to disperse CNTs uniformly in the matrix materials capture much focus in the research field. The common dispersion methods and their mechanisms of CNTs in the cement-based composites are introduced in detail, and their respective advantages and disadvantages are compared. The effects of ultrasonic time, acid treatment time, the type and amount of surfactant on the dispersion of CNTs are fully illustrated. On this basis, the methods for characterizing dispersion effect of CNTs are also discussed. The mechanical properties of the composites can be significantly improved by dispersing CNTs into the cement matrix. © 2018, Materials Review Magazine. All right reserved.
