Transformation of the strengthening and toughening modes of a poly(urethane) elastomer with hard segments of Ti3C2 MXene and its excellent triboelectric performance

Ti 3 C 2 MXenes are selected as the hard segment to prepare a poly(urethane) (PU) elastomer in this work. It provides a general method to synthesise excellent PU with integration of the structure and function by only modulating the hard segments.
