Two-dimensional titanium carbide (Ti₃C₂T_x) has accumulated tremendous interest due to its high electrical conductivity combined with hydrophilicity. However, Ti₃C₂T_x MXene is prone to oxidative deterioration and has a short storage period, and further processing is also extremely difficult. Herein, we report a highly cohesive dough state of MXene with a solid content of 19.4 wt% without binder-like additives. The surface and inside of the dough state retain an appropriate number of water molecules, which endows it with good flame retardancy, plasticity, as well as portability, and it can be easily re-diluted into gels or dispersions. Moreover, the MXene dough still exhibits excellent reversible redispersibility after being stored for 150 days at room temperature, and its electrochemical capacitance and electrical conductivity are basically the same as that of freshly synthesized MXene. In the future, such a binder-free dough state of MXene could replace traditional low-concentration MXene dispersions as an important starting material for constructing all MXene-based architectures, opening up a new avenue for the real realization of large-scale applications of MXene.

具有高再分散性的无粘结剂Ti ₃ C ₂ T _x MXene面团

二维碳化钛（Ti ₃ C ₂ T _x）由于具有高导电性和亲水性而备受关注。但是，Ti ₃ C ₂ T _xMXene易于氧化变质并且具有短的储存时间，并且进一步加工也极其困难。本文中，我们报道了MXene的高内聚面团状态，其固含量为19.4 wt％，不含粘合剂样添加剂。面团状态的表面和内部保留适当数量的水分子，这使其具有良好的阻燃性，可塑性以及可携带性，并且可以轻松地重新稀释成凝胶或分散液。此外，MXene面团在室温下储存150天后仍显示出优异的可逆再分散性，并且其电化学电容和电导率与新鲜合成的MXene基本相同。在将来，
