Ifumbire mvaruganda ipakira imyanda yimbaho ​​hamwe nigikonoshwa

Cellulose na chitine, bibiri bya biopolymer bikunze kugaragara ku isi, biboneka mu bishishwa by’ibimera na crustacean (hagati y’ahandi).Abahanga mu Ishuri Rikuru ry’ikoranabuhanga rya Jeworujiya ubu batekereje uburyo bwo guhuza byombi kugira ngo babyaze umusaruro ifumbire mvaruganda isa n’imifuka ya pulasitike.

Iyobowe na Prof. J. Carson Meredith, itsinda ry’ubushakashatsi ririmo gukora mu guhagarika nanocrystal selile ikurwa mu biti na chitin nanofibers yakuwe mu bishishwa by’ibikona mu mazi, hanyuma igatera igisubizo kuri bioavailable mu buryo butandukanye.Ibi bikoresho bikozwe kuri substrate yongeye gukoreshwa - guhuza neza kwa selile yamashanyarazi ya nanocrystal hamwe na chitin nanofibers yuzuye neza.

Iyo bimaze gukama no gukonjeshwa muri substrate, firime ibonerana iboneka ifite ihinduka ryinshi, imbaraga hamwe nifumbire.Ikirenze ibyo, irashobora kandi kurenza igipfunyika cya pulasitiki kidafumbirwa kugirango ibiryo bitangirika.Meredith yagize ati: "Ibipimo byacu by'ibanze tugereranya ibi bikoresho ni PET cyangwa polyethylene terephthalate, kikaba ari kimwe mu bikoresho bishingiye kuri peteroli ukunze kubona mu gupakira neza mu mashini zicuruza n'ibindi nk'ibyo."Ati: “Ibikoresho byacu byerekana ko 67% byagabanutse mu buryo bwa ogisijeni ugereranije na PET zimwe na zimwe, bivuze ko bishobora gutuma ibiryo birebire.”

Kugabanuka kwimikorere biterwa no kuba hariho nanocristal.Meredith yagize ati: "Biragoye ko molekile ya gaze yinjira muri kirisiti ikomeye kuko igomba guhungabanya imiterere ya kirisiti."Ati: “Ku rundi ruhande, ibintu nka PET bifite ibintu byinshi bya amorphous cyangwa bitari kristaline, ku buryo hari inzira nyinshi za molekile ntoya ya gaze kubona byoroshye.”

Ubwanyuma, firime zishingiye kuri biopolymer ntizishobora gusa gusimbuza firime ya plastike kuri ubu idashobora kwangirika iyo ijugunywe, ariko kandi ikoresha imyanda yimbaho ​​ikomoka mu nganda n’ibishishwa by’ibikona byajugunywe n’inganda zo mu nyanja.Kugeza icyo gihe ariko, ikiguzi cyo gutanga ibikoresho kurwego rwinganda kigomba kugabanuka.
