▎ 摘　　要

NOVELTY - Preparing micro-nano material dispersion liquid, involves (a) preparing a dispersion solution, where the dispersing solution includes micro-nano fiber particles, (b) using a shielding pattern to shield a through hole of a portion of a supporting film, (c) placing the supporting film on the liquid surface of the micro-nano material dispersing liquid, (d) soaking the shielding pattern into the dispersion fluid, and (e) heating the dispersant liquid under the allowing to stand state of the support film and the dispersion liquid to form a self-assembling structure on the lower surface of a support film by micro- nanoparticles and (f) drying the patterned self-assembly structure to obtain a micro nanoparticle patterning self-assembled film, where the micro-nano material comprises MXene, carbon nano-tube, polystyrene micro-sphere, molybdenum disulfide, boron nitride or oxide graphene. USE - The method ibis useful for preparing micro-nano material dispersion liquid. ADVANTAGE - The method utilizes micro-nano material particles in the dispersion liquid form a self-assembled structure only in the unshielded area of the lower surface of the support film, thus realizing the preparation of a patterned film; is simple preparation process and the low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a micro-nano material patterned film. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the method for preparing micro-nano material dispersion liquid (Drawing includes non-English language text).
