Ukusetyenziswa kweTekhnoloji yoHlulo lweMembrane kwiGraphene

I-Graphene yinto ethandwa kakhulu kwi-inorganic material mva nje, kwaye ifumene ingqwalasela ebanzi kwi-transistors, iibhetri, ii-capacitors, i-polymer nanosynthesis, kunye nokwahlulwa kwe-membrane.Izinto ezinokuthi zenzeke kwi-membrane entsha zinokuba sisizukulwana esilandelayo seemveliso zemembrane eziphambili.

Iipropati zeGraphene oxide
Igraphene oxide (GO) yifilim yobusi ene-dimensional two-dimensional planar film eyenziwe ngumaleko omnye weeathom zekhabhoni.Ukubunjwa kwayo kweekhemikhali kuqulunqwe ikakhulu ngama-athomu ekhabhoni kunye namaqela asebenzayo ane-polar oksijini.I-GO ibangelwa kuhlobo lwamaqela asebenzayo ane-oksijini.Kwaye ukusasazwa okungacacanga kwenza ulwakhiwo lwalo lwemolekyuli lube nempikiswano.Phakathi kwabo, imodeli yesakhiwo seLerf-Klinowski yamkelwa ngokubanzi, kwaye kugqitywe ukuba kukho amaqela amathathu aphambili asebenzayo kwi-GO, angala i-hydroxyl kunye namaqela epoxy abekwe kumphezulu, kunye nalawo abekwe ecaleni.carboxyl.

I-GO inokwakheka kweplani ye-dimensional-dimensional efana negraphene.Umahluko kukuba i-GO yazisa inani elikhulu lamaqela asebenzayo aqukethe i-polar oksijini kumphezulu we-carbon skeleton ngenxa ye-oxidation, njenge-O-, -COOH, -OH, njl njl. Ubukho bamaqela asebenzayo kwandisa ubunzima be-oxidation. Ulwakhiwo lweGO.Iingqimba ze-GO zixhunywe ngenani elikhulu leebhondi ze-hydrogen, kunye nesakhiwo seplani ye-dimensional-dimensional idibaniswe ngamabhondi aqinile, okwenza kube yi-hydrophilic kakhulu.I-GO yayikhe yathathwa njengento ene-hydrophilic, kodwa i-GO eneneni i-amphiphilic, ebonisa utshintsho olusuka kwi-hydrophilic ukuya kwi-hydrophobic ukusuka emphethweni ukuya embindini.Ulwakhiwo olukhethekileyo lwe-GO lunika indawo enkulu yendawo ethile, i-thermodynamics ekhethekileyo Inokubaluleka kophando oluhle kunye nethemba lokusetyenziswa kwiinkalo zebhayoloji, amayeza, kunye nezixhobo.

Kwiintsuku ezimbalwa ezidlulileyo, ijenali ephezulu yamazwe ngamazwe "Indalo" yapapasha iforum "Ion sieving by cations elawula isithuba phakathi kweefilimu zegraphene oxide".Olu phando luphakamisa kwaye luqonda ulawulo oluchanekileyo lwe-graphene inwebu nge-ion ze-hydrated, ebonisa ukusefa kwe-ion okugqwesileyo kunye nokukhutshwa kwetyuwa emanzini olwandle.ukusebenza.

Ngokoshishino, ilizwe lam linike ingqwalasela kuphando kunye nophuhliso kwicandelo legraphene ngaphambili.Ukusukela ngo-2012, ilizwe lam likhuphe ngaphezulu kwe-10 yemigaqo-nkqubo enxulumene negraphene.Ngo-2015, uxwebhu lokuqala lwenkqubo yenqanaba lesizwe "Iimbono ezininzi malunga nokuKhawulezisa iNtsha entsha kunye noPhuhliso loShishino lweGraphene" licebise ukwakha ishishini legraphene libe lishishini eliphambili, kunye nokwenza inkqubo epheleleyo yoshishino lwegraphene ngo-2020. Uthotho lwamaxwebhu anjalo njengoko iSicwangciso seMinyaka emiHlanu se-13 sifake igraphene kwintsimi yezinto ezintsha eziphuhliswe ngamandla.I-arhente iqikelela ukuba isikali sisonke semarike yegraphene yelizwe lam kulindeleke ukuba idlule kwi-10 yeebhiliyoni zeeyuan ngo-2017. Uphuhliso loshishino lwegraphene luyakhula ngokukhawuleza, kwaye iinkampani ezinxulumene nazo kulindeleke ukuba zixhamle.
