The discovery of liquid crystal (LC) phases in dispersions of two-dimensional (2D) materials has opened new opportunities

for developing aligned three-dimensional (3D) macrostructures, enabling advancements in energy-storage applications.

However, achieving suitable mechanical, electrical, and electrochemical reliability in films, a type of macrostructure,

remains challenging due to the inherent self-restacking of MXene sheets and the lack of a proper fabrication protocol for

large-scale film formation. Here, we demonstrate a sequential surface bridging strategy for MXene sheets utilizing their LC

properties and further boosting both the mechanical and electrochemical properties by facilitating in situ polymerization of

norepinephrine between the MXene interlayers.
