This invention discloses a 5-amino-1,4-naphthoquinone propyltriethoxysilane, its preparation method, and its applications. The product is prepared by a substitution reaction of 5-amino-1,4-naphthoquinone and chloropropyltriethoxysilane in the presence of an acid-binding agent. The product is an orange-brown liquid with diverse functions. When applied to silica-modified tires, compared to conventional silane coupling agents, besides the siloxy groups improving the dispersibility of silica, the electron-deficient double bonds can undergo bonding reactions with double bonds in natural rubber, further promoting the dispersion of silica in the rubber compound, improving the mechanical properties of the rubber compound, and reducing tire rolling resistance. Furthermore, the hydroxyl groups generated by the bonding reaction and the inherent amine groups in the structure can delay rubber aging, making it valuable for industrial applications.

The invention relates to tertiary amine oxidation type zwitterionic lipid, lipid nano-delivery particles and application of the tertiary amine oxidation type zwitterionic lipid and the lipid nano-delivery particles. The invention provides tertiary amine oxidation type zwitterionic lipid which is proper in size and special in structure. The tertiary amine oxidation type zwitterionic lipid can deliver hydrophilic / hydrophobic organic / inorganic contents. The lipid nano-delivery particles are prepared on the basis of the tertiary amine oxidation type zwitterionic lipid, and various contents including hydrophilic drugs, hydrophobic drugs and inorganic nano-particles can be encapsulated by regulating and controlling the ratio of the tertiary amine oxidation type zwitterionic lipid to the lipid without the tertiary amine oxidation type group. The formed lipid nanoparticles are uniform in size, stably exist in different solutions, do not agglomerate, have long blood circularity of up to at least 60 hours, have very high specific affinity to tumors, are gathered in the tumors in quantity, do not cause any obvious damage to main organs, and can be used for preparing the lipid nanoparticles. The bioavailability of the content and the cancer treatment effect are obviously improved.

The invention aims to provide a preparation method and application of a sandwich membrane filled with supporting electrolyte gel between two layers of polyolefin membranes. And the polyolefin film has a good supporting effect. The solid gel layer can well block Zn < 2 + >, reduce the ion transference number of Zn < 2 + >, relieve the generation of zinc dendrites, and inhibit the diffusion of Br2 at the same time. The supporting electrolyte in the gel can be used for ion transmission. Compared with a traditional single-layer diaphragm, the sandwich membrane can realize high coulombic efficiency and high surface capacity circulation of the flow battery, and the energy density of the battery is further improved.
