The present application relates to the technical field of thermoplastic elastomer, in particular to a disposable visual double-lumen bronchial cannula and a preparation method thereof.The ethylene-propylene thermoplastic elastomer, polypropylene resin, antibacterial silver material and antibacterial zinc oxide material are mixed, and then melt extrusion, cooling and traction are carried out to obtain a pipe material.The pipe material is sequentially subjected to water washing, alcohol washing, drying and plasma treatment to obtain a pretreated pipe material.The antibacterial hydrogel solution is obtained by adding hydroxyethyl acrylamide, acrylic acid, polyvinylpyrrolidone, propenyl quaternary ammonium salt, allyl triphenyl phosphonium bromide and 1-allyl imidazole.The pretreated pipe material is soaked in the antibacterial hydrogel solution, and then the finished product is obtained after ultraviolet irradiation.The finished product prepared by the present application has excellent antibacterial property and lubricity, and therefore has a wide application prospect in the technical field of thermoplastic elastomer.

The application discloses a near-infrared film and a preparation method thereof. The near-infrared film is prepared by the following method: mixing cadmium bromide, antimony bromide and propyl triphenyl phosphonium bromide, wherein the ratio of the sum of the molar amounts of the cadmium bromide and the antimony bromide to the molar amount of the propyl triphenyl phosphonium bromide is 1:2.001; the molar amount of the antimony bromide is 0.1% to 50% of the molar amount of the cadmium bromide; then adding a polar solvent to dissolve and filter to obtain a precursor solution, and finally using the precursor solution to prepare the near-infrared film. The application introduces the antimony element into the organic-inorganic hybrid cadmium halide, combines ligand regulation engineering and halogen regulation engineering, and prepares a novel near-infrared film. The near-infrared film realizes near-infrared light emission with a peak position of 760 nm for the first time by using the antimony element, the light emission is not affected by a matrix, the light emission efficiency is high, the stability is high, the film forming performance of the film is good, the preparation method is simple and easy to implement, and the near-infrared film has low cost and large-scale production potential.
