The present application belongs to the technical field of functional materials, and particularly relates to a coated carbon nanotube composite material and a preparation method thereof, and a functional polymer composite material and a preparation method thereof. The coated carbon nanotube composite material provided by the present application has a core-shell-shell structure coated in turn from inside to outside, wherein the carbon nanotube constitutes an inner core providing mechanical enhancement and an electrically conductive path, a silver layer coated on the surface of the carbon nanotube serves as an intermediate layer and a first antibacterial component, a copper oxide nanoparticle layer coated on the surface of the silver layer serves as an outer shell layer and a second antibacterial component, and the copper oxide layer and the silver layer form a heterojunction. The specific structure produces a synergistic effect of silver, copper oxide and carbon nanotube, so that the composite powder has the functions of high-efficiency antibiosis, antistatic and mechanical enhancement.

The invention relates to the technical field of traditional Chinese medicine bacteriostasis, in particular to a traditional Chinese medicine bacteriostatic composition based on a paulownia flower extract and a silver birch extract. Comprising 10-30 parts of a paulownia flower extract, 10-30 parts of a silver birch extract, 10-30 parts of spina date seeds, 5-20 parts of honeysuckle flowers, 5-15 parts of fructus forsythiae, 10-25 parts of radix scutellariae, 5-15 parts of dandelions, 5-15 parts of herba houttuyniae, 1-5 parts of licorice roots and 2-3 parts of a surfactant. The composition has the beneficial effects that efficient bacteriostasis is achieved, specifically, the composition with the efficient bacteriostasis effect is formed by scientifically proportioning the paulownia flower extract, the silver birch extract and other multiple traditional Chinese medicine ingredients. The composition can generate a remarkable inhibition effect on various pathogenic bacteria, and a new choice is provided for treating various diseases caused by the pathogenic bacteria; compared with traditional antibiotics, the traditional Chinese medicine antibacterial composition provided by the invention has lower toxicity. The components are all from natural plants, are harmless to human bodies, and are not easy to generate drug resistance in the use process.

This invention discloses a multifunctional medical repair ozone oil composition and its preparation method, belonging to the technical field of medical external care preparations. The composition uses 1%–60% ozonated oil and animal repair oils as its core components, and can selectively add petrolatum, vitamin E, chitosan, and natural plant fragrance essential oils. The surgical skin-specific formula can add peppermint and borneol to enhance penetration, while the gynecological formula is gentle and non-irritating. This product has multiple effects, including antibacterial and anti-inflammatory properties, antipruritic and analgesic effects, moisturizing and repairing properties, and promoting the healing of mucous membranes and skin wounds. It is suitable for gynecological intimate care, surgical skin repair, and can also be applied externally to the back to soothe respiratory discomfort and to the abdomen to relieve abdominal pain and bloating. It has a wide range of applications, high clinical value, and is suitable for large-scale production and clinical promotion.

The invention discloses a sulfonium ion-containing compound as well as a preparation method and application thereof. The structural formula of the sulfonium ion-containing compound is as follows: # imgabs0 #, R1 is independently selected from methyl, ethyl or propyl, R2 and R3 are independently selected from C1-C50 linear or branched alkyl, phenyl, alkyl-substituted phenyl or alkyl-substituted naphthenic base, and-R4 is selected from halide ions, CF3SO3 <->, BF4 <-> or HCOO <->. The sulfonium ion-containing compound has efficient antibacterial and anti-algae adhesion capabilities, has the advantages of high antifouling efficiency, good stability, good marine durability, environmental protection and the like when being applied as a marine antifouling agent, and is expected to promote further development of the marine protection field.

The present application relates to the technical field of food packaging materials, in particular to a bimetallic nano-enzyme antibacterial master batch, a preparation method thereof, an antibacterial film and application thereof. Dimethyl imidazole, basic zinc carbonate, copper salt and epsilon-polylysine are used as raw materials for extrusion to obtain a bimetallic nano-enzyme antibacterial master batch, which is then mixed with resin for blown film to prepare an antibacterial film. The antibacterial film utilizes the characteristics of the low-coordination Cu(I) sites in the bimetallic nano-enzyme Cu-ZIF-8, i.e. ROS generation in the dark and structure collapse to release epsilon-polylysine and Cu and Zn ions in a slightly acidic environment, to achieve efficient antibacterial effect in the dark and long-term antibacterial effect for high-risk perishable food, solve the problems of poor antibacterial effect in the dark and insufficient pH adaptation of existing packaging materials, and the process is controllable and easy to industrialize.
