3.3.2 MXene Based Electrochemical Microsupercapacitor Recently, MXene-based MSCs fabricated by employing a Meyer coating and spray-coating methods followed by a direct laser cutting process were reported.160, 161 However, MXene tends to be easily oxidized at high temperatures, and laser engraving was shown to easily oxidize the edge of the interdigitated MXene fingers. To solve this problem, we have proposed a simple one-step method to make the MSC by pre-patterning the substrate. The schematic in Figure 36a shows the details of this process. We first used a CO2 laser to smoothly cut the PET substrate into the desired pattern, then used direct spray-coating of MXene on the pattern to form the active material pattern; which was followed by painting of the cross-linked gel electrolyte over the entire device to complete the solid-state MSC fabrication. Raman spectroscopy and XRD were used to characterize the active MXene material Ti3C2Tx. As shown in Figure 36b, The Raman spectrum of Ti3C2Tx exhibits strong peaks at 200 and 722 cm-1, which can be assigned to the A1g modes of Ti3C2O2; the additional peaks at 286, and 630 cm-1 can be assigned to the following vibrational modes: Eg of Ti3C2(OH)2, and Eg of Ti3C2F2, respectively.162 These peaks reveal the presence of -OH, -O and -F functional groups on Ti3C2Tx MXene surface. As compared with PET substrate, Ti3C2Tx on PET shows strong (002) XRD peak located at 2θ = 7.2° with FWHM = 0.55°, with corresponding to a d-spacing of 1.2 nm (Figure 36c). The SEM image in Figure 36d shows that Ti3C2Tx electrodes have been uniformly coated on the substrate, which is confirmed in the cross-section SEM image (Figure 36e). 95PDF Image | HIGH PERFORMANCE TRIBOELECTRIC NANOGENERATOR AND ITS APPLICATIONS
