Research on the smart behavior of MCNT grafted CF/cement-based composites

To solve the disadvantages of weak bonding between the carbon fiber (CF) and the cement matrix, as well as the poor dispersion performance of multi-walled carbon nanotubes (MCNT) in cement paste, hydrothermal synthesis and chemical grafting methods were combined to graft MCNT on the surface of CF. Scanning electron microscope (SEM) and energy dispersive spectrometer (EDS) were coupled used to evaluate the grafting efficiency. Four-electrode...
