Description

Broad-spectrum antibacterial and antiviral textile based on double-long-chain ionic liquid structural monomer graft copolymerization and preparation method thereof
Technical Field
The invention relates to a textile, in particular to a broad-spectrum antibacterial and antiviral textile based on double-long-chain ionic liquid structural monomer graft copolymerization and a preparation method thereof.
Background
Infectious diseases caused by pathogenic microorganisms (such as pathogenic bacteria or viruses) have long been a major threat to human health. With the improvement of living standard and the progress of transportation technology, the range of human activities is wider, the contact is more frequent, the transmission and outbreak of serious infectious diseases occur at times, and the transmission of diseases such as pneumonia caused by influenza and coronavirus causes huge damage to human health, public health and social and economic lives.
The most effective method to prevent the spread of infectious diseases is isolation. Preventing pathogenic bacteria or viruses from contacting human bodies is an important measure for preventing the occurrence and prevalence of infectious diseases. The common textile has no inhibition effect on pathogenic microorganisms, and the pathogenic microorganisms are easy to grow and propagate on the common textile and have chances to contact and invade human bodies. The antibacterial and antiviral textile can cut off the way of transferring germs or viruses and prevent the germs and the viruses from living and propagating on the textile, thereby effectively isolating the germs or the viruses from contacting the human body, reducing the risk of the human body being invaded by the germs or the viruses and reducing the cross infection rate of the public environment. In addition, the antibacterial and antiviral textile can also prevent the textile from being damaged due to the erosion of pathogenic microorganisms, inhibit peculiar smell generated by decomposing and polluting the pathogenic microorganisms on the textile, and ensure the health and comfort of human bodies.
Currently, antibacterial and antiviral textiles are produced by mainly bonding an antibacterial agent or an antiviral functional finishing agent to the textiles in a physical adsorption manner through a post-finishing method (padding, heating, drying, and the like). The antibacterial agent and the antiviral function finishing agent comprise nano metal particles (such as nano silver, nano copper and the like, wherein the nano silver is forbidden in the United states due to the toxicity of the nano silver to human bodies), nano inorganic particles (such as nano zinc oxide and the like), metal salts (copper series and silver series salts, such as copper sulfate and the like) and some natural polymers with antibacterial and antiviral functions, such as chitosan and the like. However, the conventional production method has the disadvantages that the antibacterial component is mainly combined with the textile through physical adsorption and the like, the binding force is weak, the antibacterial and antiviral active ingredients are quickly lost after the antibacterial and antiviral active ingredients are used and washed, the antibacterial and antiviral effects of the textile are not durable, the lost antibacterial and antiviral components have potential harm to human bodies and the environment, and the types of applicable pathogenic bacteria and viruses are limited.
Disclosure of Invention
In order to solve the problems of narrow range of antibacterial and antiviral property, weak bonding fastness of antibacterial and antiviral functional groups/particles and textiles, non-lasting antibacterial and antiviral functions and the like in the prior art, the invention provides a broad-spectrum antibacterial and antiviral textile based on double-long-chain ionic liquid structural monomer graft copolymerization and a preparation method thereof.
The broad-spectrum antibacterial and antiviral textile based on the double-long-chain ionic liquid structural monomer graft copolymerization comprises a textile and at least one organic monomer, wherein the organic monomer is graft copolymerized on the textile, is an organic monomer containing a double-long-chain ionic liquid structure and has a general formula
Figure BDA0003597323720000021
Wherein A is an organic group containing a carbon-carbon double bond, C is a cationic group of an ionic liquid, X is an organic group or an organic chain segment which covalently links A and C, B 1 And B 2 Respectively a hydrophobic chain segment connected with C by a covalent bond, and D is an anionic group of the ionic liquid.
The main components of the cell membrane of bacteria and the envelope of enveloped viruses (such as influenza virus and coronavirus) are phosphate layers, the surfaces of the phosphate layers are negatively charged, so the phosphate layers are attracted by positive charges of structural groups of ionic liquid, and the phosphate layers are easily inserted into hydrophobic molecular chains to be broken, so the bacteria and the viruses die. Therefore, the group containing the hydrophobic chain segment and the ionic liquid structure has good broad-spectrum antibacterial and antiviral effects. However, the cell membranes of different kinds of bacteria and envelopes of different kinds of viruses are different in thickness, and thus, the hydrophobic chain length has a direct influence on the antibacterial and antiviral effects, and if the hydrophobic chain length is shorter, the penetration ability to the thicker cell membrane and viral envelope is weak. The invention uses the ionic liquid structure organic monomer with two long chains as the antibacterial and antiviral functional group, and the double long chain structure can more effectively destroy the cell membrane of the germ and the envelope of the virus, thereby achieving the effect of more broad-spectrum antibacterial and antiviral. Graft polymerization can firmly fix specific functional groups on the textile through covalent bonds. According to the invention, through graft polymerization, the monomer containing the double-long-chain ionic liquid structure is connected to the textile through a covalent bond, so that the textile has broad-spectrum antibacterial and antiviral functions, the durability of the functions can be ensured, and potential harm to human health and environment caused by loss of antibacterial and antiviral groups in the using process is avoided.
