“…To efficiently disperse the MWCNTs, several surfactants were exploited to prepare/modify the surface structure of the nano-reinforcements with non-covalent functionalization to increase the dispersion state and the interface bonding with the surrounding matrix. Two types of surfactants were used in the present work, one ionic (SDBS) and one non-ionic (Triton X-100), which have been widely used in the dispersion of such reinforcements in resin matrices [ 32 , 33 ].…”

Multi-wall carbon nanotubes (MWCNTs) exhibit exceptional mechanical and electrical properties and can be used to improve the mechanical and piezoelectric properties of cement-based materials. In the present study, the effect of different MWCNT concentrations as well as different types of surfactants and a superplasticizer were examined to reinforce, at the nanoscale, a white cement mortar typically used for the restoration of monuments of cultural heritage. It was shown that sodium dodecylbenzenesulfonate (SDBS) and Triton X-100 surfactants slightly decreased the white cement mortars’ electrical resistivity (by an average of 10%), however, the mechanical properties were essentially decreased by an average of 60%. The most suitable dispersion agent for the MWCNTs proved to be the superplasticizer Ceresit CC198, and its optimal concentration was investigated for different MWCNT concentrations. Carboxylation of the MWCNT surface with nitric acid did not improve the mechanical performance of the white cement nanocomposites. The parametric experimental study showed that the optimum combination of 0.8 wt% of cement superplasticizer and 0.2 wt% of cement MWCNTs resulted in a 60% decrease in the electrical resistivity; additionally, the flexural and compressive strengths were both increased by approximately 25% and 10%, respectively.

“…To the best of our insight, no investigation has been performed on the waviness of CNTs in composites within the sight of Van der Waals interphase districts. One of the primary downsides of most investigations on foreseeing the mechanical properties of CNT composites is the immediate utilization of the micromechanics conditions reasonable for stringy composites [67,86,90,92,96,97,101,107]. In particular, they supplant the cross section structure of a CNT with a strong fibre.…”

“…The covalent bonding between the MWCNTs‐COOH and the epoxy molecules would inhibit the migration of MWCNTs into matrix so as to form a MWCNTs‐rich layer between carbon fiber and resin matrix. The effective adhesion between the epoxy matrix and the CNTs surface is beneficial to the interfacial engineering …”

For the purpose of improvement in interfacial property of carbon fiber composites through a facile process, the carboxyl-functionalized multiwalled carbon nanotubes (MWCNTs-COOH) were incorporated into the surface of JH-T800 carbon fiber using sizing and deposition technology. The surface morphology of MWCNTs-COOH-modified carbon fibers and fracture surfaces of unidirectional carbon fiber composites were observed via scanning electron microscopy and atomic force microscopy. According to the results of composites fragmentation test, the adoption of MWCNTs-COOH-modified carbon fibers resulted in the improved carbon fiber/ epoxy matrix interfacial bonding and interlaminer property by 32.1% and 31.9%, respectively. Through the combination of the above two kinds of pretreating process of carbon fibers, a stress transition layer with the gradient distribution of MWCNTs was built between carbon fiber and resin matrix, which was favorable for releasing stress concentration and hindering the propagation of crack, resulting in a higher reinforcing efficiency for the existing carbon fiber composites.
