1) Nhanganyaya yekuwedzera graphite
Inowedzera graphite, inozivikanwawo se flexible graphite kana worm graphite, imhando itsva ye carbon material. Yakawedzerwa graphite ine zvakawanda zvakanaka, senge hombe chaiyo surce nharaunda, yakakwirira pamusoro pekuita, yakanaka kugadzikana kwemakemikari uye yakakwirira tembiricha kuramba. Iyo yakajairwa kugadzirira maitiro ekuwedzera graphite kutora yakasikwa flake graphite sechinhu, kutanga kuburitsa girafu inowedzerwa kuburikidza neoxidation process, wozoiwedzera kuita yakawedzera graphite. Kana paine tembiricha yakakwira, iyo yakawedzera graphite zvinhu inogona kuwedzera ipapo 150 ~ 300 nguva muhukuru, uye shanduko kubva kune flake kuenda kune honye senge, kuitira kuti chimiro chakasununguka, chine porous uye chakakombama, nzvimbo yepamusoro inowedzerwa, simba repamusoro rinovandudzwa. , iyo adsorption simba reflake graphite inowedzerwa, uye honye senge graphite inogona kunyudzwa yega, kuitira kuti zvinhu zvive nemabasa emurazvo retardant, kuisa chisimbiso uye adsorption, uye inoshandiswa zvakanyanya muminda yehupenyu, mauto, kuchengetedzwa kwezvakatipoteredza. , indasitiri yemakemikari uye zvichingodaro.
2) Kugadzirira nzira yekuwedzera graphite
Kemikari oxidation uye electrochemical oxidation inonyanya kushandiswa kuwedzera graphite. Iyo yechinyakare makemikari oxidation nzira ine yakapusa maitiro uye yakagadzikana mhando, asi kune mamwe matambudziko akadai sekutambisa asidhi uye yakakwira sarufa yezvigadzirwa. Nzira ye electrochemical haishandisi maoxidants, mhinduro yeasidhi inogona kudzokororwa kakawanda, nekusvibiswa kwezvakatipoteredza uye kudhura kwakaderera, asi goho rakaderera uye zvinodiwa zve electrode zvinhu zvakakwirira. Parizvino, inongogumira pakutsvagisa marabhoritari. Kuwedzera kune dzakasiyana nzira dzeoxidation, nzira mbiri idzi dzine imwechete mushure mekurapa senge deacidification, kugeza mvura uye kuomesa. Chemical oxidation nzira ndiyo inonyanya kushandiswa nzira kusvika parizvino. Iyo nzira yakakura uye yakave yakakurumbira uye yakashandiswa muindasitiri.
3)Musiyano pakati pekuwedzera graphite uye graphene
Graphene uye yakawedzera graphite ine maitiro akasiyana mune zvese zviri zviviri chimiro uye nzvimbo yekushandisa. Yakawedzerwa graphite inogona kushandiswa seyakagadzirwa zvinhu zvekugadzira graphene. Semuenzaniso, iyo nzira yeHummers inogona kushandiswa kuwana graphene oxide ne ultrasonic kuwedzera kwegraphite oxide. Kana iyo yakawedzerwa graphite yakabviswa kuita chidimbu chimwe chete, inova graphene. Kana ikakururwa kuita zvidimbu zvakati wandei, izvikamu zvishoma zvegraphene. Graphene nanosheets inogona kugadzirirwa kubva kune anopfuura gumi kusvika makumi matatu.
4)Inoshanda minda yekushandisa yeakawedzera graphite
1. Kushandiswa kwezvinhu zvokurapa
Iyo yekupfeka yekurapa inogadzirwa neakawedzerwa graphite inogona kutsiva yakawanda yechinyakare gauze nekuda kweayo akawanda emhando yepamusoro.
2. Kushandiswa kwezvinhu zvehondo
Iyo yakawedzerwa graphite inopwanyika kuita hupfu hwakatsetseka, iyo ine kupararira kwakasimba uye kunyura maitiro kune infrared wave. Kugadzira poda yayo yakanaka kuita yakanakisa infrared shielding material inoita basa rakakosha muphotoelectric countermeasure muhondo yemazuvano.
3. Kushandiswa kwezvinhu zvekuchengetedza zvakatipoteredza
Yakawedzerwa graphite inoshandiswa zvakanyanya mumunda wekuchengetedzwa kwezvakatipoteredza nekuda kwekuderera kwayo, isina-chepfu, isina kusvibiswa-isina, kurapwa kuri nyore uye yakanakisa adsorption.
4. Biomedical zvinhu
Carbon zvinhu zvine kuenderana kwakanyanya nemuviri wemunhu uye yakanaka biomedical zvinhu. Semhando nyowani yekabhoni zvinhu, yakawedzera graphite zvinhu zvine yakanakisa adsorption maitiro eiyo organic uye biological macromolecules. Iyo ine yakanaka biocompatibility, isiri-chepfu, isinganakidze uye haina mhedzisiro. Iyo ine tarisiro yakakura yekushandisa mune biomedical zvinhu.
