“…Therefore, carbon black nanoparticles are introduced in the production of DCI, which endows it with DCI with another important characteristic of conductivity. [26][27][28][29][30] Interestingly, the conductivity, good dispersion, and strong adhesion of the DCI are also important properties for fabricating sensors. 26,27,[31][32][33][34][35] In particular, compared with other carbon materials (e.g., graphene, carbon nanotubes, and their derivatives), the commercial and industrial DCI has the advantage of extremely low cost.…”
