A new nanomaterial nano-silver coating that can solve the problem of biological deface of coatings

China Paint Online News Information: Dalian University of Technology university student "founder" Cao Jian was recently invited to participate in the "innovation, win in Shunde - 100 colleges and universities innovative talent to see Shunde" activities. What he didn't expect was that he brought a new type of bio-nanomaterials to Guangdong Demei Fine Chemical Co., Ltd. favor, to achieve investment cooperation intention, is about to enter the market.
cao Jian brought the project called "nano-silver coating", is a new type of biological nanomaterials. Based on the observation of mussels, Cao Jian, under the leadership of his teachers at the School of Life Sciences and Technology, developed a surface-modified technique based on the in-place growth of nano-silver particles of polydestamine surface coating. Combining the surface modification ability of polydamine with the antibacterial and anti-biological attachment ability of nano-silver, the surface modification of metals, polymers, paints and other material surfaces can be carried out, so that it has the dual functions of antibacterial and anti-aquatic adhesion respectively.Cao Jian,
, said that "nano-silver coating" can not only solve the economic and ecological challenges of modern coating research biodeface, but also meet the development requirements of a new generation of medical materials antibacterial and anti-infective.
, it is understood that maritime transport, marine resources development, seaport and sea defense construction and other fields need a large number of surface protection materials. The U.S. Navy spends $1 billion a year cleaning up the surface of ships because of the large adsorption of microorganisms and marine flora and fauna on the surface of the material, which is a significant hazard to marine transport and the exploration and exploitation of marine resources. Traditional marine anti-fouling coatings are toxic to the marine environment and marine life to a great extent. Cao Jian's team studied the "nano-silver bio-anti-fouling coating", strong anti-biological attachment ability, biological friendliness, in shipping, offshore engineering construction, submarine fiber optic cable pipeline construction and other fields have broad application prospects, and make electroplating on glass or plastic possible, has potential research value.
Cao Jian's team also uses polydhopamine to film the properties of a variety of material surfaces, in the medical succulation surface preparation of "nano-silver antibacterial coating", Glochine-negative bacteria and Terrain-positive bacteria have excellent inhibitory effect, can make people postoperative wounds from bacterial infection. Applying only to medical susceptibles can greatly reduce the risk of bacterial infection, allow patients to reduce the use of antibiotics, and speed up postoperative wound healing.
