2-dimensional MXene particle surface-modified with functional group containing saturated or unsaturated hydrocarbon, preparation method thereof and use thereof

A passivated 2-dimensional MXene particle, comprising:

• a 2-dimensional MXene particle surface-modified with a functional group comprising a saturated or unsaturated hydrocarbon;
• and
• an organic protective film formed on a surface of the surface-modified 2-dimensional MXene particle,
• wherein the functional group is selected from the group consisting of a phosphonate and a silane,
• wherein the phosphonate is represented by Formula 1 or 2, and the silane represented by Formula 4:
• wherein R1, R2, R3, and R4 are independently a saturated or unsaturated hydrocarbon, a C1 to C6 alkoxy, or a hydroxyl group, and R5 is a saturated or unsaturated hydrocarbon, with a proviso that each of R1, R2, R3, and R4 is not a saturated or unsaturated hydrocarbon or each of R1, R2, R3, and R4 is not a hydroxyl group,
• wherein the surface-modified 2-dimensional MXene particle with a functional group comprising a saturated or unsaturated hydrocarbon is covered with an organic polymer, or dispersed in an organic polymer, forming the protective film.
