Zvinangwa: Kugadzira novel polypropylene composite zvinhu zvine antimicrobial chiitiko nekuwedzera akasiyana marudzi emhangura nanoparticles.

Nzira nemhedzisiro: Mhangura simbi (CuP) uye mhangura oxide nanoparticles (CuOP) yakaiswa mune polypropylene (PP) matrix.Aya macomposites anopa maitiro akasimba eantimicrobial kurwisa E. coli zvinoenderana nenguva yekubatana pakati pemuenzaniso nebhakitiriya.Mushure memaawa mana chete ekusangana, aya masampuli anokwanisa kuuraya anopfuura makumi mapfumbamwe neshanu muzana ehutachiona.CuOP mafirita anoshanda zvakanyanya kubvisa mabhakitiriya pane CupP mafirita, zvichiratidza kuti antimicrobial pfuma inoenderera mberi nerudzi rwemhangura.Cu²⁺ yakaburitswa kubva muhuwandu hwemusanganiswa inokonzera maitiro aya.Uyezve, ma PP/CuOP macomposites anopa mwero wepamusoro wekuburitsa kupfuura PP/CuP macomposites munguva pfupi, achitsanangura maitiro eantimicrobial.

Mhedziso: Mapolypropylene macomposites anobva pamhangura nanoparticles anogona kuuraya utachiona hweE. coli zvichienderana nekuburitswa kweCu²⁺ kubva mukuwanda kwezvinhu.CuOP inoshanda zvakanyanya seantimicrobial filler kupfuura Cup.

Kukosha uye kukanganisa kwechidzidzo: Zvatikawana zvinovhura manyorerwo ezviyo zveion-copper-delivery epurasitiki zvinhu zvakavakirwa paPP ine yakamisikidzwa mhangura nanoparticles ine simba rakakura seantimicrobial agents.
