“…0.007 g, 0.014 g, 0.021 g of MWCNT and 0.0035 g, 0.007 g, 0.014 g of MXene were added to 5 mL of DMF respectively, ultrasonicated for 1 h to disperse evenly, afterward, 0.7 g of PAN was added, the composite solutions were stirred at 58 C for 6 h and then used for electrospinning; in the spinning precursor solution, the mass fractions of PAN were 14%, 50 the mass fractions of MWCNT were 1%, 2%, and 3%, the mass fractions of MXene were 0.5%, 1%, and 2% respectively. The six films were named PAN/CNT-1, PAN/CNT-2, PAN/CNT-3, PAN/MX-0.5, PAN/MX-1, and PAN/MX-2 respectively…”
