Khoom nta
1) Dab tsi yog spin txheej?
Spin txheej yog txheej txheem siv los tso cov yeeb yaj kiab nyias nyias mus rau hauv cov substrates.Feem ntau me me ntawm cov khoom siv txheej yog siv rau ntawm qhov chaw ntawm lub substrate, uas yog spinning ntawm qis ceev los yog tsis spinning txhua.Lub substrate yog ces tig ntawm ceev mus txog 10,000 rpm kom kis tau cov txheej txheej los ntawm centrifugal quab yuam.Lub tshuab siv rau txheej txheej yog hu ua spinner coater, lossis tsuas yog spinner.
Kev sib hloov yog txuas ntxiv thaum cov kua ntws tawm ntawm cov npoo ntawm lub substrate, kom txog rau thaum lub thickness ntawm zaj duab xis xav tau.Cov kuab tshuaj siv feem ntau yog volatile, thiab ib txhij evaporates.Qhov siab dua qhov angular ceev ntawm spinning, lub thinner zaj duab xis.Lub thickness ntawm zaj duab xis kuj nyob ntawm qhov viscosity thiab concentration ntawm cov tshuaj, thiab cov hnyav.[2]Pioneering theoretical tsom xam ntawm spin txheej tau ua los ntawm Emslie li al., thiab tau txuas ntxiv los ntawm ntau tus kws sau ntawv tom ntej (xws li Wilson li al., [4] uas tau kawm txog tus nqi ntawm kev sib kis hauv cov txheej spin; thiab Danglad-Flores li al., [5] leej twg pom ib qho kev piav qhia thoob ntiaj teb los kwv yees cov yeeb yaj kiab tso tawm tuab).
Spin txheej yog dav siv nyob rau hauv microfabrication ntawm functional oxide txheej ntawm iav los yog ib tug siv lead ua substrates siv sol-gel precursors, qhov twg nws yuav siv tau los tsim ib tug nyias nyias films nrog nanoscale thicknesses.[6]Nws yog siv ntau heev hauv photolithography, tso cov txheej txheem ntawm photoresist txog 1 micrometer tuab.Photoresist feem ntau spun ntawm 20 mus rau 80 revolutions ib ob rau 30 mus rau 60 vib nas this.Nws kuj yog dav siv rau fabrication ntawm planar photonic lug ua los ntawm polymers.
Ib qho zoo dua rau spin txheej nyias zaj duab xis yog qhov sib xws ntawm cov yeeb yaj kiab thickness.Raws li tus kheej-leveling, thicknesses tsis txawv ntau tshaj 1%.Txawm li cas los xij, spin txheej thicker films ntawm polymers thiab photoresists tuaj yeem ua rau cov hlaws loj loj uas nws cov kev npaj muaj qhov txwv lub cev.
2) Cov txheej txheem spinning ua haujlwm li cas?
Cov txheej txheem no ua haujlwm los ntawm kev ua tib zoo tswj xyuas qhov nrawm txheeb ze rau ntau yam khoom siv ntawm cov tshuaj.Viscosity yog qhov tseem ceeb ntawm cov khoom no vim nws txiav txim siab qhov kev tiv thaiv rau cov dej ntws tsis sib xws, uas yog qhov tseem ceeb hauv kev ua tiav qhov zoo ib yam.Spin txheej yog tom qab nqa tawm thoob plaws ntau qhov ceev ceev, los ntawm tsawg li 500 revolutions ib feeb (rpm) kom ntau li 12,000 rpm - nyob ntawm qhov viscosity ntawm cov tshuaj.
Viscosity tsis yog cov khoom ntiag tug nkaus xwb ntawm kev txaus siab hauv cov txheej txheej, txawm li cas los xij.Nto nro kuj tuaj yeem cuam tshuam cov yam ntxwv ntws ntawm cov tshuaj, thaum feem pua cov khib nyiab tuaj yeem cuam tshuam qhov xav tau ntawm cov yeeb yaj kiab nyias nyias kom ua tiav cov khoom siv kawg (xws li hluav taws xob txav).Spin txheej yog tom qab ua tiav nrog kev nkag siab tag nrho ntawm cov khoom siv cuam tshuam, nrog ntau cov kev hloov kho kom haum rau cov yam ntxwv sib txawv (ntws, viscosity, wettability, thiab lwm yam).
Spin txheej tuaj yeem ua tiav siv qhov pib zoo li qub lossis dynamic, txhua qhov tuaj yeem raug programmed rau cov neeg siv-txhais acceleration ramping thiab ntau yam spin speeds.Nws tseem yog ib qho tseem ceeb uas yuav tsum tau tso cai rau lub sijhawm fume tso tawm thiab lub sijhawm ziab vim tias qhov cua tsis zoo tuaj yeem ua rau pom qhov tsis zoo thiab tsis sib xws.Piv txwv li: Swirl qauv yuav qhia tau hais tias qhov tso pa tawm siab dhau rau cov tshuaj uas yuav siv sij hawm ntev dua kom qhuav.Tsis muaj ib qho loj-haum-tag nrho cov kev daws teeb meem thaum nws los txog rau cov txheej txheem spinning, thiab txhua txoj kev yuav tsum tau ua nrog ib tug holistic mus kom ze rau lub substrate thiab txheej txheej nyob rau hauv nqe lus nug.
3) Txheej txheej xaiv?
Raws li 1.60 Photochromic Lens SHMC, super hydrophobic txheej yog tib txoj kev xaiv rau nws.
Super hydrophobic txheej kuj hu ua crazil txheej, tuaj yeem ua rau cov lo ntsiab muag tsis muaj dej, antistatic, tiv thaiv plam thiab roj tsis kam.
Feem ntau hais lus, super hydrophobic txheej tuaj yeem muaj 6 ~ 12 lub hlis.
