The utility model belongs to the technical field of photothermal desalination, specifically discloses a solar interface evaporation system, including casing, dome and inner bag main part, the inner bag main part is installed in the casing, is equipped with the evaporation recess on the inner bag main part, and the evaporation recess is equipped with the photothermal conversion material layer, the dome is covered with the casing, is used for making the external light to gather and irradiate on the photothermal conversion material layer in the evaporation recess through the dome, the photothermal conversion material layer adopts cuttlefish juice melanin and silk gourd network composite material layer. The utility model can realize efficient photothermal desalination, keep excellent photothermal conversion and evaporation efficiency, and have long -term operation stability high, need not manual intervention, the advantage that cost is low, can effectively solve traditional solar evaporation system stability is poor, cost is high, the problem of depending on manual control, provides brand -new solution for the practicality of photothermal desalination.

This application provides a method for preparing a hemostatic material and the hemostatic material itself. The method includes: preparing an ink mixture using a washing buffer and ink sac; adding a cryoprotectant composed of trehalose, ascorbate palmitate, and alginate oligosaccharides to form a protective mixture; obtaining cuttlefish ink powder through rapid freezing and staged temperature-increasing drying; mixing the cuttlefish ink powder with a phosphate extraction buffer, followed by ultrasonic disruption and enzymatic hydrolysis with a mixed enzyme; obtaining the supernatant by centrifugation and freeze-drying to obtain an active ingredient powder; dissolving the active ingredient powder in an acetate-sodium acetate buffer solution, adding chitosan and ε-polylysine, and adjusting the pH to 7.0–8.5 to form a cuttlefish ink composite solution; adding CaCl2 solution to construct a gel-like substance, followed by freeze-drying to obtain the hemostatic material. This method improves the stability and physiological activity of the active ingredients in the hemostatic material, resulting in a hemostatic material with small particle size, strong antioxidant properties, and good hemostatic effect.
