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.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., uas tau kawm txog tus nqi ntawm kev sib kis ntawm cov txheej spin; thiab Danglad-Flores li al. universal piav qhia los kwv yees lub deposited zaj duab xis thickness).
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.Classification thiab lub hauv paus ntsiab lus ntawm photochromic lens
Photochromic lens raws li lub lens discoloration qhov chaw tau muab faib ua photochromic lens (hu ua "base change") thiab membrance layer discoloration lens (hu ua "film change") ob yam.
Lub substrate photochromic lens yog ntxiv tshuaj lom neeg ntawm silver halide nyob rau hauv lub lens substrate.Los ntawm cov tshuaj tiv thaiv ionic ntawm silver halide, nws yog decomposed rau hauv nyiaj thiab halide xim rau lub lens nyob rau hauv lub teeb muaj zog stimulation.Tom qab lub teeb tsis muaj zog, nws tau muab tso rau hauv cov nyiaj halide kom cov xim sib dua.Cov txheej txheem no feem ntau yog siv rau iav photochroimc lens.
Zaj duab xis hloov lub lens tshwj xeeb yog kho nyob rau hauv cov txheej txheem lens txheej.Piv txwv li, spiropyran tebchaw yog siv rau high-speed spin txheej rau ntawm qhov chaw ntawm lub lens.Raws li kev siv ntawm lub teeb thiab ultraviolet lub teeb, cov qauv molecular nws tus kheej tuaj yeem hloov mus rau thiab tawm kom ua tiav cov txiaj ntsig ntawm kev hla lossis thaiv lub teeb.
3. Txheej txheej xaiv?
Raws li 1.67 photochromic lens, super hydrophobic txheej yog tib txheej 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.
