A kind of carbon nanotube antibacterial coating and its manufacturing process

Abstract

A kind of carbon nanotube antibacterial coating, the addition amount by mass percentage is respectively: 85% environmental protection coating, 5% carbon nanotube, 3% polypeptide molecule and 7% infrared absorber, this invention solves the problem of traditional preparation The coating produced by the process does not have the deficiency of antibacterial effect, which opens up a new field in the coating industry; broadens the application field of carbon nanotubes, reduces its damage to human lungs and skin, and reduces the risk of antibiotics while antibacterial. The risk of abuse to the human body and the future; through special components and production methods, the damage of toxic substances to the human body is greatly reduced, while saving energy and environmental protection, it also harmonizes the coexistence of people and the environment. This feature can be widely used in hospitals, families and In the environment with a large number of people, such as handrails of various building materials, doors and windows, heat sinks and other places where bacteria are easy to breed.

Description

technical field [0001] The patent of the present invention relates to the technical field of components of an antibacterial coating and its configuration method, especially a carbon nanotube antibacterial coating and its manufacturing process. The coating has significant antibacterial and environmental protection through the research and development and production of special components. Protective effect, this feature can be widely used in hospitals, families and environments with a large number of people, such as handrails of various building materials, doors and windows, heat sinks and other places where bacteria are easy to breed. Background technique [0002] Carbon nanotubes, also known as bucky tubes, are one-dimensional quantum materials with a special structure. The radial dimension of this special structure is on the order of nanometers, and the axial dimension is on the order of microns. The two ends of the tube are basically closed. Due to its small size effect an...

Problems solved by technology

[0008] However, due to the light weight of carbon nanotubes, they can spread in the air, especially can be inhaled and deposited in the lungs, which can cause adverse effects on the lungs, which has aroused people's great attention to the biological effects and safety of carbon nanotubes So far, many scholars at home and abroad have expounded the toxicological research on carbon nanotubes. Carbon nanotubes have certain toxic effects on cells in vitro and in vivo. The main cause of biological toxicity is oxidative stress, that is, carbon nanotubes The electron active points (electron-accepting or electron-donating groups) of the tube can interact with oxygen molecules to form some oxygen free radicals such as superoxide anion, and then generate additional reactive oxygen species (ROS) through oxidation reactions, resulting in oxidative stress reactions , resulting in an imbalance of the oxidation-antioxidant antagonism system in the body, leading to apoptosis or acute and chronic inflammatory reactions in tissues
