Investigating the rheology of 2D titanium carbide (MXene) dispersions for colloidal processing: Progress and challenges

Abstract Among 2D materials, MXenes (especially their most studied member, titanium carbide) present a unique opportunity for application via colloidal processing, as they are electrically conductive and chemically active, whilst still being easily dispersed in water. And since the first systematic study of MXene rheology was published 2018 ( Rheological Characteristics Titanium Carbide (MXene) Dispersions: A Guide Processing by Akuzum, et al.), numerous works have presented small amounts rheological data which together contribute to deeper understanding topic. This work reviews on all MXene-containing formulations, including liquid crystals, mixtures non-aqueous colloids, been used processes such stamping, patterning, 3D printing. An empirical model aqueous carbide viscosity has developed, recommendations made help researchers more effectively future analysis. Graphic abstract
