Herein, we spincast aqueous colloidal Ti2CTx (MXene) solutions into conductive, transparent films with figures of merit (FOM), that are as good as Ti3C2Tx or un-doped chemically vapor-deposited graphene. When normalized by the number of transition metal atoms, the FOM is the highest ever reported for a MXene film. At about 2.7 x 10(5) cm(-1) the absorbance coefficient of Ti2CTx is quite comparable to that of Ti3C2Tx. Quantitative relationships between film properties-conductance and transparency-and colloidal solution concentration and spin speeds are developed providing a road map for future work. [GRAPHICS] IMPACT STATEMENT In a first, we spincast aqueous colloidal Ti2CTx (MXene) solutions into conductive, transparent films with figures of merit-5-that are as good as Ti3C2Tx or un-doped CVD graphene.
