Iinjongo: Ukuphuhlisa i-novel polypropylene izinto ezidibeneyo kunye nomsebenzi we-antimicrobial ngokongeza iintlobo ezahlukeneyo ze-nanoparticles zethusi.

Iindlela kunye neziphumo: Isinyithi sobhedu (CuP) kunye ne-copper oxide nanoparticles (CuOP) zifakwe kwi-polypropylene (PP) matrix.Ezi ngxubevange zibonisa ukuziphatha okunamandla kwe-antimicrobial ngokuchasene ne-E. coli exhomekeke kwixesha loqhagamshelwano phakathi kwesampuli kunye nebhaktheriya.Emva nje kwe-4 h yoqhagamshelwano, ezi sampuli ziyakwazi ukubulala ngaphezu kwe-95% yeebhaktheriya.Izihluzi zeCuOP zisebenza ngakumbi ukuphelisa ibhaktheriya kune-CuP fillers, ebonisa ukuba ipropathi ye-antimicrobial ixhomekeke ngakumbi kuhlobo lwamasuntswana obhedu.UCu²⁺ ukhutshiwe kubuninzi bedibaniso unoxanduva lokuziphatha.Ngaphezu koko, i-PP / CuOP i-composites ibonisa izinga eliphezulu lokukhululwa kune-PP / Cup composites ngexesha elifutshane, lichaza ukuthambekela kwe-antimicrobial.

Izigqibo: Imidibaniso yePolypropylene esekwe kwinanoparticles yobhedu inokubulala iibhaktheriya ze-E. coli ngokuxhomekeke kwisantya sokukhululwa kweCu²⁺ kubuninzi bezinto.IiCuOP zisebenza ngakumbi njengesihluzi se-antimicrobial kune-CuP.

Ukubaluleka kunye neempembelelo zophononongo: Iziphumo zethu zivula izicelo zenoveli zezi zixhobo zeplastiki ze-ion-copper-delivery esekelwe kwi-PP ene-nanoparticles yobhedu edibeneyo enobuchule obukhulu njenge-antimicrobial agents.
