Lub Hom Phiaj: Txhawm rau tsim cov ntaub ntawv tshiab polypropylene sib xyaw nrog cov tshuaj tua kab mob los ntawm kev ntxiv ntau hom tooj liab nanoparticles.

Cov txheej txheem thiab cov txiaj ntsig: Copper hlau (CuP) thiab tooj liab oxide nanoparticles (CuOP) tau kos rau hauv polypropylene (PP) matrix.Cov khoom sib xyaw no nthuav tawm cov cwj pwm muaj zog tiv thaiv kab mob E. coli uas nyob ntawm lub sijhawm sib cuag ntawm tus qauv thiab cov kab mob.Tom qab tsuas yog 4 teev ntawm kev sib cuag, cov qauv no tuaj yeem tua ntau dua 95% ntawm cov kab mob.CuOP fillers muaj txiaj ntsig zoo tshem tawm cov kab mob ntau dua li CuP fillers, qhia tias cov khoom siv tshuaj tua kab mob ntxiv nyob ntawm seb hom tooj liab.Cu²⁺ tso tawm los ntawm ntau qhov sib xyaw yog lub luag haujlwm rau tus cwj pwm no.Ntxiv mus, PP/CuOP composites nthuav tawm tus nqi tso tawm ntau dua li PP/CuP cov khoom sib xyaw hauv lub sijhawm luv luv, piav qhia txog cov tshuaj tiv thaiv kab mob.

Cov ntsiab lus: Polypropylene composites raws li tooj liab nanoparticles tuaj yeem tua cov kab mob E. coli nyob ntawm qhov tso tawm ntawm Cu²⁺ los ntawm cov khoom siv ntau.CuOP muaj txiaj ntsig zoo li tshuaj tua kab mob ntau dua li CuP.

Qhov tseem ceeb thiab kev cuam tshuam ntawm txoj kev tshawb fawb: Peb qhov kev tshawb pom tau qhib cov ntawv tshiab ntawm cov khoom siv yas ion-tooj ​​liab-xa khoom raws li PP nrog cov khoom siv tooj liab nanoparticles uas muaj peev xwm zoo li cov tshuaj tua kab mob.
