Abstract Gallium‐based liquid metal (LM) has attracted great attention for constructing flexible electronic devices due to its excellent deformability and electrical conductivity. However, large surface tension makes it difficult be uniformly dispersed in polymers, which severely limits wide applications. Hence, a surfactant‐free approach is proposed prepare stable LM microspheres against precipitation coalesce by facile ultrasonication via cellulose nanocrystal (CNC) stabilized LM‐in‐water Pickering emulsion (PE), where CNCs are employed as emulsifiers their partial wettability with both water phases, strong electrostatic adsorption hydrogen bonding interactions LM. So far, reports about PE CNC‐stabilized inorganic material still rare. CNC/LM direct‐writing inks on various substrates delicate patterns. The pristine patterns show photothermal conversion localized plasma resonance effect of microspheres.
