This invention provides a flexible solar evaporator with a vertical perforation structure, its preparation method, and its application. The preparation method of the flexible solar evaporator includes constructing a polyurethane / carbon black composite system using polyurethane as a flexible matrix and carbon black as a photothermal conversion material. Ice crystals are directionally grown to form a vertical ice crystal structure through directional freezing. After drying, the ice crystals are removed to obtain a flexible solar evaporator with a vertical through-hole structure. The flexible solar evaporator provided by this invention utilizes the excellent elasticity and mechanical stability of the polyurethane matrix, making it less prone to damage. Combined with carbon black as a photothermal conversion material to construct a composite structure, the polyurethane matrix encapsulates the carbon black during construction, forming a tightly bonded continuous phase. This retains the flexible characteristics of the evaporator while enhancing its structural strength, preventing flaking and damage caused by external impacts or water erosion during use.
