It is reported that Southwest Jiaotong University has taken the lead in the development of a nano-ZnO zinc whisker antibacterial material with a four-needle structure in China and was first approved by the China Antibacterial Materials and Products Industry Association “Antimicrobial Markâ€, making China the second largest country in the world after Japan. A country that can mass produce this antibacterial material.
Zinc Oxide Whisker is a type of semiconductor needle-like single crystal with internal carrier tunable, and its crystal has a considerable part of atomic oxygen. Atomic Oxygen also has strong oxidation activity, which can destroy the biological activity and metabolism of bacteria. In order to achieve antibacterial purposes.
Antibacterial wall coatings produced using this material have long-term, high-efficiency, broad-spectrum antimicrobial properties. The test results by the national authoritative testing agency showed that the antibacterial rate of common harmful bacteria reached more than 99%, exceeding the relevant national standards. In addition, oral toxicity, eye and skin irritation tests have all reached the highest level of “non-toxic grade†chemical substance classification.
Nano zinc oxide whisker antibacterial materials also have broad application prospects in the fields of national defense, transportation, chemical industry, light industry, electronics and so on. At present, Xinyuan Company, Foxconn Group, Chengdu Banknote Printing Company, Sichuan Anhe Paper and other companies have applied this technology to product production.
