Mhando dzese dzezvinhu dziri kushandiswa mu 3D kudhinda mazuva ano, Kevlar uye fiberglass yakasimbisa nylon. etc. Asi kunyange chiri chokwadi icho simba rezvinhu zvakakosha, ndizvo zvakaitawo chimiro chemukati chechinhu 3D yakadhindwa. Munguva pfupi yapfuura, boka revaongorori kubva ku MIT yakagadzira imwe yeakasimba asi akareruka zvinhu nekumanikidza uye nekunyungudutsa graphene zvikamu.
Kusvika parizvino, vaongorori vanga vachinetseka kushandura simba rema graphene-maviri kuita mativi-matatu. Asi dhizaini nyowani kubva kuMIT, a graphene kumisikidzwa yakafanana ne chipanji, inogona kusimba kakapetwa kagumi pane simbi, iine huwandu hwezvikamu zvishanu chete muzana.
Zvakawanikwa nekambani yeMIT yekutsvagurudza zvakataurwa munguva pfupi yapfuura mumagazini Sayenzi Kufambira mberi. Chinyorwa ichi chakanyorwa pamwe naMarkus Buehler, McAfee purofesa weinjiniya uye mukuru weMIT's Dhipatimendi reCivil neEnjiniya Injiniya (CEE); CEE muongorori wesainzi Zhao Qin; Akapedza kudzidza Gang Seob Jung; Uye Min Jeong Kang Meng, kirasi ya2016.
Mune iyo geometry yeiyo Graphene chimiro ndiyo kiyi
Zvavakawana, sekureva kweMIT, zvinoratidza kuti "yakakosha maficha matsva e3D ine zvakawanda zvine chekuita nekujairika kwayo kwejometri kumisikidzwa pane izvo zvinhu pachazvo, zvichiratidza kuti zvakafanana zvivakwa zvinogona kuwanikwa kubva kwakasiyana zvinhu kana tikashandisa zvakafanana geometric maitiro. »
Chikwata chakaburitsa yakatsiga uye yakasimba dhizaini yakafanana nemakorari uye zvisikwa zvidiki zvinozivikanwa sedhiatomu, uchishandisa musanganiswa wekupisa uye kumanikidza kumanikidza madiki mafuru e graphene. Iwo mafomu anokonzeresa ane yakakura nzvimbo yenzvimbo inoenderana nehukuru hwavo, uye akasimba zvisingaite. Dzinotaridzika kunge Nerf mabhora - zvinhu zvakakomberedzwa, asi zvizere nemakomba. Aya maumbirwo akaomarara anozivikanwa segyroids., uye Buehler akati "hazvigoneke" kuvasika vachishandisa zvigadzirwa zvakajairika. Kune bvunzo dzevarabhoritari, timu yakashandisa 3D yakadhindwa mamodheru eiyo gyroids, yakawedzera zviuru zvakapetwa saizi yavo yechisikigo.
Chikwata chakaisa iwo mamodheru e3D kumhando dzakasiyana dzemuchina uye yekumanikidza bvunzo, vachishandisa avo ezvitambi mhando kuti vateedzere mhinduro yemagetsi pasi pemutoro. Mune imwe yemasampuli edu vakaiwana iyo ne 5% yeiyo simbi yesimbi yakawana kagumi kusimba kwezvinhu zvataurwa".
Iyo 3D graphene zvinhu, zvakaumbwa nenzvimbo dzakakombama pasi pe deformation, inoita semashizha epepa. Iyo bepa rinogona kuunyana zviri nyore, nekuti harina kusimba pamwe nehupamhi nekureba. Asi kana bepa rikaputirwa muhubhu, simba riri padhuze nechubhu rakakura kwazvo. Iyo geometric kurongeka kweiyo graphene flakes mushure mekurapa ine yakafanana dhizaini.
Zvingabvira kunyorera
Pakati peanogona kunyorera, zvinoratidzika izvo geometric maficha akawanikwa nezvimwe zvinhu anogona kushandiswa, senge ma polymers kana simbi, kuitira kuti tora zvakafanana simba mabhenefiti pane yakaderera kugadzirwa mutengo. Iko kune zvakare mukana wekushandisa polymer kana simbi zvidimbu sematemplate, uchishandisa kemikari mhute dura pamberi pekupisa uye kumanikidza kurapwa kuti uvafukidze ne graphene. Shure kwaizvozvo, iyo polymer kana simbi inogona kubviswa kuitira kuchengetedza iyo 3D graphene mune gyroid fomu. Iyi porous geometry inogona kushandiswa pakuvaka zvivakwa zvakakura, sebhiriji. Iyo yaitogona kupa yakanaka kuputira kune zambuko, nekuda kwehuwandu hwenzvimbo yakavharwa yemhepo.
