1)Ukuqaliswa kwegraphite ekwandiswayo
Igraphite eyongezelekayo, eyaziwa ngokuba yigraphite eguquguqukayo okanye igraphite yombungu, luhlobo olutsha lwezinto zekhabhoni. Igraphite eyandisiweyo ineengenelo ezininzi, njengendawo enkulu ye-surce ethile, umsebenzi ophakamileyo womphezulu, uzinzo oluhle lweekhemikhali kunye nokumelana nobushushu obuphezulu. Inkqubo eqhelekileyo yokulungiselela igraphite eyandisiweyo kukuthatha igraphite yendalo njengesixhobo, kuqala ukuvelisa igraphite enokwandiswa ngenkqubo ye-oxidation, kwaye emva koko iyandise ibe yigraphite eyandisiweyo. Kwimeko yobushushu obuphezulu, imathiriyeli eyandisiweyo yegraphite inokwandisa ngokukhawuleza amaxesha angama-150 ~ 300 kumthamo, kwaye itshintshe ukusuka kwiflake ukuya kwi-worm efana, ukuze ulwakhiwo lukhululeke, lugobe kwaye lugobile, indawo yomphezulu iyandiswa, amandla angaphezulu aphuculwe. , i-adsorption force ye-flake graphite iphuculwe, kwaye i-worm efana ne-graphite inokuthi ifakwe ngokwayo, ukuze izinto zibe nemisebenzi ye-flame retardant, ukutywinwa kunye ne-adsorption, kwaye isetyenziswa ngokubanzi kwiinkalo zobomi, umkhosi, ukhuseleko lokusingqongileyo. , imboni yeekhemikhali njalo njalo.
2)Ukulungiselela indlela yegraphite eyandisiweyo
I-Chemical oxidation kunye ne-electrochemical oxidation zisetyenziswa kakhulu kwigraphite eyandisiweyo. Indlela yendabuko ye-oxidation yeekhemikhali inenkqubo elula kunye nomgangatho ozinzile, kodwa kukho iingxaki ezifana nokuchithwa kwe-asidi kunye nomxholo ophezulu wesulfure weemveliso. Indlela ye-electrochemical ayisebenzisi i-oxidants, isisombululo se-asidi sinokuphinda sisetyenziswe ngamaxesha amaninzi, kunye nongcoliseko oluphantsi lokusingqongileyo kunye neendleko eziphantsi, kodwa isivuno siphantsi kwaye iimfuno zezinto ze-electrode ziphezulu. Okwangoku, ilinganiselwe kuphela kuphando lwebhubhoratri. Ukongeza kwiindlela ezahlukeneyo ze-oxidation, iindlela ezimbini zinexesha elifanayo lokunyanga njenge-deacidification, ukuhlamba amanzi kunye nokomisa. Indlela ye-Chemical oxidation yeyona ndlela isetyenziswa kakhulu ukuza kuthi ga ngoku. Inkqubo ivuthiwe kwaye iye yaziwa ngokubanzi kwaye isetyenziswa kwishishini.
3)Umahluko phakathi kwegraphite eyandisiweyo kunye negraphene
Igraphene kunye negraphite eyandisiweyo ineentsebenzo ezahlukeneyo kwisakhiwo sezinto zombini kunye nentsimi yesicelo. Igraphite eyandisiweyo ingasetyenziswa njengemathiriyeli ekrwada kwimveliso yegraphene. Ngokomzekelo, indlela ye-Hummers ingasetyenziselwa ukufumana i-graphene oxide ngokunyuka kwe-ultrasonic ye-graphite oxide. Xa igraphite eyandisiweyo ikhutshiwe ibe yiqhekeza elinye, iba yigraphene. Ukuba ihlulwe ibe ziileya ezininzi, ziileya ezimbalwa zegraphene. Iinanosheets zegraphene zinokulungiswa ukusuka kwimigangatho engaphezu kweshumi ukuya kwe-30.
4)Iinkalo zesicelo esisebenzayo segraphite eyandisiweyo
1. Ukusetyenziswa kwezinto zonyango
Isinxibo sezonyango esenziwe ngegraphite eyandisiweyo sinokuthatha indawo ye-gauze yemveli ngenxa yeempawu zayo ezintle.
2. Ukusetyenziswa kwezinto zomkhosi
Igraphite eyandisiweyo iyatyunyuzwa ibe ngumgubo ocolekileyo, oneempawu zokusasazeka okunamandla kunye nokufunxa kumaza e-infrared. Ukwenza umgubo wayo ocolekileyo ube yimathiriyeli ebalaseleyo yokhuselo lwe-infrared idlala indima ebalulekileyo kwi-photoelectric countermeasure kwimfazwe yanamhlanje.
3. Ukusetyenziswa kwezixhobo zokukhusela indalo
Igraphite eyandisiweyo isetyenziswa ngokubanzi kwinkalo yokhuseleko lokusingqongileyo ngenxa yokuxinana kwayo okuphantsi, okungeyotyhefu, ukungangcoliseki, unyango olulula kunye ne-adsorption egqwesileyo.
4. Izinto zeBiomedical
Imathiriyeli yeCarbon inokuhambelana okugqwesileyo nomzimba womntu kwaye iyimathiriyeli elungileyo yebhayoloji. Njengohlobo olutsha lwezinto zekhabhoni, izinto ezandisiweyo zegraphite zineempawu ezibalaseleyo ze-adsorption ze-organic and biological macromolecules. Ine-biocompatibility elungileyo, ayinayo ityhefu, ayinancasa kwaye ayinaziphumo ebezingalindelekanga. Inombono obanzi wesicelo kwizinto ze-biomedical.
