▎ 摘　　要

NOVELTY - A vertical orientation assembly of two-dimensional sheet material is prepared by configuring two-dimensional sheet material as colloid dispersion, using micro-needle in colloidal dispersion to construct scratches in same sliding direction at distance in colloidal dispersion, and drying. USE - The method is used for preparing vertical orientation assembly of two-dimensional sheet material in field of recycling and utilization of energy including solar water evaporation. ADVANTAGE - The two-dimensional sheet material has accurately designed and controlled orientation structure, accelerates electrolyte transmission performance in capacitor, and performs high-efficiency vertical heat conduction. DETAILED DESCRIPTION - A vertical orientation assembly of two-dimensional sheet material is prepared by configuring two-dimensional sheet material as 0.5-00 mg/g colloid dispersion, using micro-needle with diameter of 10-1000 mu m in colloidal dispersion at speed of 0.001-2000 mm/second to construct scratches in same sliding direction at distance x in colloidal dispersion, and drying. x= less than or equal to L; and L=width of scratch caused by sliding of single microneedle in colloidal dispersion.
