This solution relates to the coatings field and proposes an aqueous nano-dispersion of far-infrared negative oxygen ion material. By weight, it comprises: 300-350 parts water; 35-45 parts wetting agent; 40-60 parts dispersant; 25-35 parts defoamer; 35-45 parts multifunctional additive; 5-7 parts thickener; 400-600 parts activated far-infrared negative oxygen ion material; 1-3 parts accelerator; and 3-5 parts shielding agent. This solution designs a multi-component synergistically promoting activated far-infrared negative oxygen ion material, which can improve the hemispherical spectral emissivity in the 4-14μm band, even reaching above 0.95 in the key 8-12μm band, effectively promoting formaldehyde decomposition with a long-lasting effect, while also improving antibacterial properties.

The invention discloses an acidic tumor microenvironment activated nano probe as well as a synthesis method and application thereof, and belongs to the technical field of nano material preparation. In order to solve the problems of low treatment efficiency, lack of tumor targeting and the like caused by limitation of hypoxia of a tumor microenvironment when the existing photosensitizer is applied to a photodynamic therapy (PDT) process, a metal Fe < 2 + >, an anti-angiogenic drug thalidomide and a photosensitizer hematoporphyrin monomethyl ether approved by FDA are self-assembled, so that the anti-angiogenic drug thalidomide is prepared. The low pH response type intelligent nano diagnosis and treatment probe is prepared. Before the probe is degraded at a tumor part, the photodynamic therapy performance is opened, and a magnetic resonance imaging (MRI) signal is closed. Along with continuous enrichment of the material in tumor tissues, under low-pH stimulation of a tumor microenvironment, an MRI signal is gradually opened and thalidomide is released, oxidative stress is amplified by increasing ROS / consuming GSH, tumor cell ferroptosis is induced, and finally an excellent anti-tumor effect is achieved in cooperation with chemical kinetics / chemotherapy / photodynamic force.

The invention discloses a preparation method of a polyimide fiber solid electrolyte membrane. The polyimide fiber solid electrolyte membrane is formed by compounding a metal organic framework material, polyimide fibers and polyethylene oxide fibers, the preparation method comprises the following steps: firstly, preparing a composite fiber membrane with a core-shell structure by a coaxial electrostatic spinning process, wherein the core is polyethylene oxide / metal organic framework composite fiber; the shell is a polyimide / metal organic framework composite fiber, the vacuum freeze drying treatment temperature is-40 to-60 DEG C, and the treatment time is 24-48 hours. And after rolling by a roller press, soaking in a lithium hexafluorophosphate-containing ethylene carbonate and ethyl methyl carbonate solution, and drying to obtain the polyimide fiber solid electrolyte membrane. The polyimide fiber solid electrolyte membrane developed by the invention is improved in mechanical property, Young modulus, ionic conductivity, lithium ion transference number and use voltage, and is expected to be applied to all-solid-state lithium ion batteries.
