Abstract
Abstract Surface chemistry and interlayer engineering determines the electrical properties of 2D MXene. However, it remains challenging to regulate the surface and interfacial chemistry of MXene simultaneously. Herein, simultaneous modulation of Ti 3 C 2 T x MXene surface termination and layer spacing by alkali treatment are achieved. The electrical and electromagnetic properties of Ti 3 C 2 T x are investigated in detail with respect to KOH and ammonia concentration dependence. A high concentration of KOH caused the Ti 3 C 2 T x layer spacing to expand to 13.7 Å and the surface O/F ratio to increase to 33.84. Because of its weaker ionization effect, ammonia provides finer tuning compared to the drastic…
