“…For the formed smart materials to form an effective conductive network, the multi-walled carbon nanotubes should be uniformly dispersed in the epoxy polymer matrix, and the aforementioned studies have shown that the degree of dispersion plays a key role in the stress–resistance response [ 41 , 42 , 43 ]. Therefore, in order to avoid the phenomenon of non-uniform dispersion due to large van der Waals forces caused by the large specific surface area and small nanoparticle size, in this study, multi-walled carbon nanotubes were first ground in an agate mortar for 30 min and then mixed thoroughly with the dispersant DMF with mechanical stirring for 20 min, then sonicated for 1 h with an ultrasonic disperser (UH450 Oulior).…”

“…Within the harsh monitoring environment of asphalt pavements, the author’s team conducted a series of related studies in the development of new sensors for pavements [ 41 , 42 , 43 ]. Smart-material-based tensile strain sensing elements have been developed, and the high accuracy and viability of the sensing elements have been verified.…”

“…The axial compression test was performed to demonstrate that the accuracy of the developed sensor was acceptable. Similarly, Su et al [20] introduced a modify epoxy/anhydride blend as the sensitive components of the strain sensor. The linearity, repeatability and measurement accuracy of the sensors were also verified.…”
