3results about How to "Efficient antibacterial" patented technology

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.

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 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.
