Pahuhopu: E hoʻomohala i nā mea hoʻohui polypropylene hou me ka hana antimicrobial ma o ka hoʻohui ʻana i nā ʻano nanoparticles keleawe like ʻole.

Nā ʻano a me nā hopena: Ua hoʻokomo ʻia nā metala keleawe (CuP) a me nā nanoparticles copper oxide (CuOP) i loko o kahi matrix polypropylene (PP).Hāʻawi kēia mau mea hoʻohui i ke ʻano antimicrobial ikaika e kūʻē iā E. coli e pili ana i ka manawa pili ma waena o ka hāpana a me ka bacteria.Ma hope o 4 mau hola o ka hoʻopili ʻana, hiki i kēia mau laʻana ke pepehi ma mua o 95% o ka bacteria.ʻOi aku ka maikaʻi o nā mea hoʻopihapiha CuOP i ka hoʻopau ʻana i ka bacteria ma mua o nā hoʻopiha CuP, e hōʻike ana e pili ana ka waiwai antimicrobial i ke ʻano o ka ʻāpana keleawe.ʻO Cu²⁺ i hoʻokuʻu ʻia mai ka hapa nui o ka composite ke kuleana no kēia ʻano.Eia kekahi, hāʻawi ka PP/CuOP composites i kahi kiʻekiʻe o ka hoʻokuʻu ʻana ma mua o nā composites PP/CuP i ka manawa pōkole, e wehewehe ana i ke ʻano antimicrobial.

Nā hopena: Hiki i nā polypropylene composites ma muli o nā nanoparticles keleawe ke pepehi i ka bacteria E. coli ma muli o ka hoʻokuʻu ʻana o Cu²⁺ mai ka nui o ka mea.ʻOi aku ka maikaʻi o CuOP ma ke ʻano he antimicrobial filler ma mua o CuP.

ʻO ke koʻikoʻi a me ka hopena o ke aʻo ʻana: Ua wehe kā mākou ʻike i nā noi hou o kēia mau mea ion-copper-delivery plastic material ma muli o PP me nā nanoparticles keleawe i hoʻokomo ʻia me ka mana nui e like me nā mea antimicrobial.
