Halloysite nanotubes (HNT) waa nanotubes dhoobo ah oo si dabiici ah u soo baxa kuwaas oo loo isticmaali karo qalab horumarsan sababtoo ah qaab dhismeedka tuubbada bannaan ee gaarka ah, biodegradability, iyo qalabka farsamada iyo dusha sare.Si kastaba ha ahaatee, isku dhejinta nanotubes dhoobada ah waa mid adag sababtoo ah la'aanta hababka tooska ah.

Marka la eego, maqaal lagu daabacay joornaalka ACS Applied Nanomaterials ayaa soo jeedinaya istaraatiijiyad wax ku ool ah oo loogu talagalay abuurista qaababka HNT ee la amray.Marka la qalajiyo kala firdhiyaashooda aqueous iyadoo la isticmaalayo rotor magnetic, nanotubes dhoobo ayaa la isku toosiyay substrate galaas.
Marka ay biyuhu uumi baxaan, kicinta kala firdhinta aqueous GNT waxay abuurtaa xoogagga dhogorta ee nanotubeska dhoobada ah, taasoo keenaysa inay is waafajiyaan qaabka siddooyinka koritaanka.Waxyaabo kala duwan oo saameeya qaabka HNT ayaa la baadhay, oo ay ku jiraan feejignaanta HNT, lacagta nanotube, heerkulka qalajinta, cabbirka rotor-ka, iyo mugga dhibicda.
Marka laga soo tago arrimo jireed, iskaanka mikroskoobyada elektaroonigga ah (SEM) iyo mikroskoobyada iftiinka (POM) ayaa loo isticmaalay in lagu barto qaab-dhismeedka microscopic-ka iyo kala-soocidda siddooyinka alwaax ee HNT.
Natiijooyinku waxay muujinayaan in marka xoogga HNT uu ka sarreeyo 5 wt%, nanotubes dhoobada ah waxay gaadhaan isku dheelitirnaan qumman, iyo feejignaanta sare ee HNT waxay kordhisaa qallafsanaanta dusha sare iyo dhumucda qaabka HNT.
Intaa waxaa dheer, qaabka HNT wuxuu kor u qaaday isku-xirnaanta iyo kordhinta unugyada fibroblast mouse (L929), kuwaas oo lagu arkay inay ku koraan isku-dhafka nanotube ee dhoobada iyadoo loo eegayo habka xiriirinta.Sidaa darteed, habka fudud ee degdega ah ee hadda jira ee isku toosinta HNT ee substrates adag ayaa leh suurtogalnimada in la sameeyo matrix ka jawaabaya unugga.
Hal-cabbir (1D) nanoparticles sida nanowires, nanotubes, nanofibers, nanorods iyo nanoribbons sababtoo ah qalabkooda makaanikada, elektiroonigga ah, indhaha, kulaylka, noolaha iyo magnetic.
Halloysite nanotubes (HNTs) waa nanotubes dhoobo ah oo dabiici ah oo leh dhexroorka dibadda ee 50-70 nanometers iyo dalool gudaha ah oo ah 10-15 nanometer oo leh qaacidada Al2Si2O5 (OH) 4·nH2O.Mid ka mid ah sifooyinka gaarka ah ee nanotubes-kaani waa mid ka duwan kiimiko gudaha / dibadda ah (aluminium oxide, Al2O3 / silicon dioxide, SiO2), kaas oo u oggolaanaya beddelaadkooda xulashada.
Sababo la xiriira biocompatibility iyo sunta aadka u hooseeya, nanotubes dhoobada ah waxaa loo isticmaali karaa biomedical, cosmetics iyo codsiyada daryeelka xayawaanka sababtoo ah nanotubes dhoobada waxay leeyihiin nanosafety aad u fiican ee dhaqamada unugyada kala duwan.Nanotubes dhoobada ah waxay leeyihiin faa'iidooyinka qiimaha jaban, helitaanka ballaaran, iyo wax ka beddelka kiimikada silane ku salaysan oo sahlan.
Jihada xidhiidhka waxa loola jeedaa ifafaalaha saamaynta jihaynta unugga ee ku salaysan qaababka joomatari sida nano/grooves-ka yar ee substrate-ka.Iyada oo horumarinta injineernimada unugyada, ifafaale xakamaynta xidhiidhka ayaa noqday mid si ballaaran loo isticmaalo si loo saameeyo qaab-dhismeedka iyo abaabulka unugyada.Si kastaba ha ahaatee, habka bayoolojiga ee xakamaynta soo-gaadhista ayaan weli caddayn.
Shaqada hadda jirta waxay muujineysaa habka fudud ee sameynta qaabka giraanta koritaanka HNT.Habkan, ka dib marka lagu dabaqo dhibicda HNT ee kala firdhisanaanta muraayadda wareegsan, dhibicda HNT ayaa la isku riixaa inta u dhaxaysa laba goobood oo xidhiidhsan (sliishka iyo rotor magnetic) si ay u noqdaan kala firdhisan oo dhex mara xididka.Ficilka waa la ilaaliyaa oo la fududeeyaa.uumiga dareere badan oo ku yaal cidhifka xididdada.
Halkan, xoogga dhogorta ee uu dhaliyo rotor magnetic rotor wuxuu keenaa HNT ee cidhifka xididka si uu u dhigo dusha sare ee silbashada jihada saxda ah.Marka ay biyuhu uumi baxaan, xoogga xiriirku waxa uu dhaafaa xoogga isku dhejinta, isaga oo u riixaya xariiqda xiriirka dhanka xarunta.Sidaa darteed, marka la eego saameynta isku-dhafka ah ee xoogga xiiridda iyo xoogga xididka, ka dib uumi-baxa dhamaystiran ee biyaha, qaabka geed-ring ee HNT ayaa la sameeyay.
Intaa waxaa dheer, natiijooyinka POM waxay muujinayaan qulqulka muuqda ee qaab dhismeedka HNT ee anisotropic, kaas oo sawirada SEM ay u leeyihiin isugeynta isku midka ah ee nanotubes dhoobada.
Intaa waxaa dheer, unugyada L929 oo lagu dhaqay nanotubes dhoobo-ring sanadle ah oo leh qiyaaso kala duwan oo HNT ah ayaa la qiimeeyay iyadoo lagu saleynayo habka xiriirinta.Halka, unugyada L929 ay muujiyeen qaybinta random ee nanotubes dhoobada qaab giraanta koritaanka leh 0.5 wt.% HNT.Qaab dhismeedka nanotubes dhoobada leh ee NTG ee 5 iyo 10 wt %, unugyo dhaadheer ayaa laga helaa jihada nanotubes dhoobada.
Gebagebadii, naqshadaha giraanta kobaca ee macroscale HNT ayaa la sameeyay iyadoo la isticmaalayo kharash-ku-ool ah iyo farsamo cusub si loogu habeeyo nanoparticles si habaysan.Samaynta qaab dhismeedka nanotubes dhoobada ayaa si weyn u saameeya feejignaanta HNT, heerkulka, kharashka dusha sare, cabbirka rotor, iyo mugga dhibicda.Heerarka HNT ee u dhexeeya 5 ilaa 10 wt.% waxa ay siiyeen habab dhoobo ah oo aad loo dalbay, halka 5 wt.% arragtiyadani ay muujiyeen birefringance midabyo dhalaalaya.
Isku-dubbaridka nanotubes dhoobada ah ee jihada xoogga jeexjeexa ayaa la xaqiijiyay iyadoo la adeegsanayo sawirada SEM.Marka la kordhiyo xoogga NTT, dhumucda iyo qallafsanaanta daaha NTG ayaa kor u kacaya.Sidaa darteed, shaqada hadda jirta waxay soo jeedinaysaa hab fudud oo lagu dhisayo dhismayaal ka soo jeeda nanoparticles oo ka sarreeya meelo waaweyn.
