1. Electrical conductivity measurements for the vacuum-filtered (V x ,Ti 1-x ) 3 C 2 T z MXene nanosheet (x=0-90) films measured by a four-point probe are shown in Figure 8 and Table S7. Interestingly, the Ti-rich compositions of (V x ,Ti 1-x ) 3 C 2 T z MXenes, specifically for x=0, 0.1, and 0.3 show relatively higher conductivity values than the compositions with x=0;For the highest V-rich composition (x=0.9), an increase in conductivity was observed. However, all conductivity values for the
2. This trend in conductivity values observed for (V x ,Ti 1-x ) 3 C 2 T z MXenes is also comparable to the trend predicted and measured for their "211' counterparts, (V x ,Ti 1-x ) 2 CT z , reported in the literature.[41] However, conductivities reported here for (V x ,Ti 1-x ) 3 C 2 T z are almost an order of magnitude higher than those reported for (V x ,Ti 1-x ) 2 CT z , for compositions with lower and higher V contents;the range of 10 5 S/m order-ofmagnitude range
