Solution processing of two-dimensional nanomaterial inks guarantees efficient, straightforward fabrication functional films, coatings, flexible devices, etc. Despite the excellent solution processibility and viscoelasticity MXene aqueous inks, formulation nonaqueous with great affinity to both hydrophilic hydrophobic substrates has proven quite challenging, limiting practical applications MXenes in printing/coatings on various substrates. Here, surface chemistry is manipulated by asymmetrically grafting polystyrene further concentrating flakes into additive-free Janus organic inks. The modified nanosheets exhibit hydrophilicity one side hydrophobicity other. As a result, ensure broad dispersibility polar nonpolar solvents, which turn greatly extends ink shelf life slowing down oxidation kinetics. sheets dispersed toluene at room temperature remain 90% initial solids after 1 month storage. engineering formation uniform yet firm, large-area coatings or These demonstrate improved photothermal properties chemical stability as well good electromagnetic interference shielding performance. This strategy provides simple cost-effective way promote performance electronics variety applications.
