Senhengo yakakosha yemhuri yekabhoni yezvinhu, mapepa egraphite anoratidza tarisiro yakafara yekushanda musimba, zvemagetsi, kemikari engineering, uye aerospace nekuda kwekunaka kwazvo kwekupisa nemagetsi conductivity, kugadzikana kwemakemikari, uye simba remuchina. Mumakore achangopfuura, nekukurumidza kufambira mberi kwezvinhu zvesainzi neinjiniya, kutsvagisa pamapepa egraphite kwakaramba kuchidzika, zvichikonzera kufambira mberi kwakakura mukugadzirwa kwezvimiro, kuita optimization, uye kushanda kwekushandisa.
1. Graphite Sheet Kugadzirira Technology
Iyo nzira yekugadzirira yemagraphite mapepa inokanganisa zvakananga microstructure yavo uye macroscopic zvimiro, uye nekudaro inoramba iri yakakosha nzvimbo yekutsvagisa. Sechinyakare, mapepa egraphite anowanzo gadzirwa kuburikidza nekumisikidza molding kana yakakwirira-temperature graphitization ye natural flake graphite, asi nzira idzi dzinoguma nekuwanda uye kufanana. Mumakore achangopfuura, vatsvakurudzi vakagadzira nzira dzakasiyana-siyana dzekugadzirira, kusanganisira kemikari vapor deposition (CVD), polymer precursor conversion, uye nzira dzakasanganiswa (semuenzaniso, magraphite composites ane resin, simbi, kana ceramics).
Pakati pawo, tekinoroji yeCVD inokwanisa kuisa-mafirimu emhando yepamusoro emagraphite panzvimbo yepasi. Nekugadzirisa chiyero uye tembiricha yemagasi anogadzirisa (akadai semethane, hydrogen, uye argon), nhamba yegraphite layers uye saizi yezviyo inogona kunyatsodzorwa. Uyezve, pyrolytic graphitization yakavakirwa papolymer precursors senge polyimide (PI) yakwezvawo kutarisisa. Nzira iyi inoshandisa-tembiricha yepamusoro (inodarika 2800 degree) kugadzira carbonize uye kurongazve maorganic matter kuita chimiro chegraphite. Iwo anoguma graphite mapepa anoratidza yakakwirira kutaridzika uye yakanakisa yekupisa conductivity.
2. Performance Optimization and Modification Research
Iko kukwidziridzwa kwekuita kwema graphite mapepa kunonyanya kutarisisa pakupisa kwekushisa, kufambisa kwemagetsi, kusimba kwemagetsi, uye kusagadzikana kwekuora. Nezvekupisa kwemafuta, vatsvakurudzi vakaona kuti kuwedzera interlayer orientation yemagraphite sheets (senge kuburikidza nekukunguruka-kubatsirwa kutaridzika) kunogona kunatsiridza zvakanyanya mu-plane thermal conductivity. Thermal conductivity yemamwe ma graphite sheets anotarisisa zvakanyanya kupfuura 1500 W/(m·K). Nezvemagetsi conductivity, doping nezvinhu zvakaita senitrogen uye boron kana kuunza nhanho dzekusimbisa senge kabhoni nanotubes uye graphene zvinogona kuwedzera kunatsiridza kutakura kwavo maelectronic.
Panyaya yesimba remuchina, nepo magraphite sheets aine simba rakanyanya rekumanikidza, simba rawo rekusimba uye kusimba zvakadzikira, zvichidzikamisa kushandiswa kwawo mukutakura-zvimiro zvinotakura. Kugadzirisa izvi, vatsvakurudzi vakatsvaga mhinduro dzakaita secarbon fiber-yakasimbisa graphite composites uye graphite/metal composite sheets, kusimbisa huwandu hwema mechanical properties nekuunza yakakwirira-simba rechipiri{4}}chikamu chezvinhu. Uyezve, kune chaiwo maapplication (akadai semakemikari ekudzivirira corrosion), tekinoroji yekuputira pamusoro (senge nickel plating, SiC coating, kana Al₂O₃ coating) iri kushandiswa kusimudzira kushorwa kwemagraphite mapepa.
3. Kufambira mberi muKushanda Kwekushanda
Zvinhu zvakasiyana-siyana zvema graphite sheets zvakavaita kuti zvive zvakakosha mumhando dzakasiyana-siyana. Muchikamu chesimba remagetsi, -mashizha ekudziya egraphite anoshandiswa zvakanyanya mu lithium battery thermal management, semiconductor device heat dissipation, uye solar thermal conversion systems. Semuenzaniso, magirafu mapepa anoshandiswa sematanho ekupisa kupisa mumotokari yemagetsi bhatiri packs, zvinobudirira kuderedza kupisa kwebhatiri uye kuwedzera hupenyu hwebhatiri.
Muchikamu chezvemagetsi, magraphite sheets, nekuda kwekunaka kwawo kwemagetsi, anoshandiswa mumagetsi emagetsi anochinjika, maelectromagnetic shielding materials, nezvinobvisa kupisa kwemagetsi-zvidziyo zvemagetsi zvine simba. Uyezve, kugadzirwa kwegraphene-graphite composite sheets kunopa mhinduro dzinobvira kune inotevera-chizvarwa chepamusoro-frequency electronic devices. Muindasitiri yemakemikari, mapepa egraphite, nekuda kwekukwira kwawo-kupisa nekuora{7}}kusingaviriki, isarudzo yakanaka kune reactor linings, sealing materials, nepamusoro-masefa ekupisa.
4. Remangwana Rekutsvaga Mazano
Kunyange zvazvo tsvakiridzo yepepa remagraphite yakawana mabhindauko akawanda, zvimhingamipinyi zvichiripo, zvakaita semutengo wakakwirisa we-yekugadzira zvinhu zvakakura uye kusagadzikana kwakakwana mune dzimwe nzvimbo dzakanyanyisa. Tsvakurudzo yenguva yemberi inogona kutarisa pane zvinotevera nzvimbo:
1. Tekinoroji yekugadzira yakasvibira uye yakaderera-inodhura: Kugadzira simba-magadzirirwo emagetsi anoshanda uye anobudirira kusimudzira kushandiswa kweindasitiri kwemagraphite sheets;
2. Multifunctional integrated design: Kugadzirisa kupisa, magetsi, uye mechanical properties kuburikidza necomposite structural design;
3. Kunyanya kuchinjika kwezvakatipoteredza: Kudzidza-kugadzikana kwenguva refu kwemapepa egraphite pasi pekupisa kwakanyanya, mwaranzi wakasimba, kana kukora kwakanyanya;
4. Kuongorora maapplication ari kubuda: Zvishandiso mu quantum mudziyo kutonhora, tekinoroji yemuchadenga, uye zvinhu zvebiomedical.
Muchidimbu, graphite sheet research iri kukurumidza kukura. Nekubudirira kuri kuramba kuchienderera mberi mukugadzira michina, kutonga kwemaitiro, uye maapplication anoshanda, basa rayo mukugadzirwa kwepamusoro-nemaindasitiri ari kusimukira anozonyanya kukosha.
