Copper oxide nano-ufandi bulauni-wakuda zitsulo okusayidi ufa ndi osiyanasiyana ntchito.Kuphatikiza pa ntchito ya catalysts ndi masensa, gawo lofunikira la nano-copper oxide ndi antibacterial.

The antibacterial process of metal oxides akhoza kufotokozedwa mophweka motere:

Pansi pa chisangalalo cha kuwala ndi mphamvu yayikulu kuposa kusiyana kwa bandi, ma electron awiriawiri opangidwa ndi ma elekitironi amalumikizana ndi O2 ndi H2O m'chilengedwe, ndipo mitundu ya okosijeni yopangidwa ndi okosijeni ndi ma radicals ena aulere amakhudzidwa ndi mamolekyu achilengedwe mu cell, potero amawola. cell ndi kukwaniritsa antibacterial cholinga cha.Popeza CuO ndi semiconductor yamtundu wa p, ili ndi mabowo (CuO) +, omwe amatha kulumikizana ndi chilengedwe kuti azisewera antibacterial kapena antibacterial effect.

Kafukufuku wasonyeza zimenezonano-CuOali ndi antibacterial properties kwambiri motsutsana ndi Escherichia coli, Bacillus subtilis, Salmonella, Pseudomonas aeruginosa ndi Staphylococcus aureus, ndipo antibacterial effect pa Pseudomonas aeruginosa ndi Salmonella ndizodziwikiratu.

Nano-copper oxidendi zabwino zotsutsana ndi dzimbiri zamatabwa.Kuwonongeka kwachuma kwachindunji chifukwa cha kuwonongeka kwa nkhuni zomwe zimagwiritsidwa ntchito chaka chilichonse padziko lonse lapansi sikungatheke.Kuwonetsetsa kuti matabwawo ndi olimba, osawononga kwanthawi yayitali komanso kuwononga chilengedwe, zinthu zochepetsera kawopsedwe komanso zopanda chlorine zamitengo ndizodzaza ndi chiyembekezo chogwiritsa ntchito.Wood odana ndi dzimbiri zimadalira mlingo wa malowedwe odana dzimbiri zipangizo mu microstructure matabwa.Poyerekeza ndi ufa wamba wamkuwa, tinthu tating'onoting'ono ta nano-mkuwa titha kuphimba mitundu yambiri yamkati mwa matabwa.Chifukwa chake, poyerekeza ndi zida zachikhalidwe zotsutsana ndi dzimbiri, tinthu tating'ono ta nano-mkuwa titha kukwaniritsa cholinga cha anti-corrosion bwino.

Kuphatikiza apo, kuwonjezera nano-copper oxide ku mapulasitiki, ulusi wopangira, zomatira ndi zokutira zimatha kukhalabe ndi ntchito yayikulu kwa nthawi yayitali ngakhale m'malo ovuta.

Hongwu Nano angapereke mkuwa okusayidi ufa kapena nano mkuwa okusayidi kubalalitsidwa ndi tinthu kukula osiyanasiyana 30-50nm.Takulandirani kuti mukambirane ndi kuyitanitsa.
