Vim lawv cov khoom siv photoisomerization tshwj xeeb, azo tebchaw yuav tsum muaj kev ruaj ntseg thiab kev ua tau zoo-cov tshuab sib xyaw ua ke nrog ntau yam matrices lossis cov khoom siv rau cov ntawv thov xws li cov yeeb yaj kiab nyias, cov txheej txheem ntse, cov khoom siv micro/nano, thiab cov khoom siv roj ntsha. Kev xaiv cov khoom siv tsis tsuas yog cuam tshuam rau cov qauv kev ruaj ntseg thiab kev ua haujlwm ntawm azo molecules tab sis tseem cuam tshuam ncaj qha rau cov neeg kho tshuab, kho qhov muag, thiab ib puag ncig adaptability ntawm cov cuab yeej kawg. Yog li ntawd, cov txheej txheem xaiv cov khoom yuav tsum ua raws li cov hauv paus ntsiab lus xws li kev sib raug zoo, kev ruaj ntseg, kev ua kom haum, thiab kev taw qhia kev ua tau zoo, tsim kev txiav txim siab zoo- ua txoj hauv kev.
Compatibility yog qhov yuav tsum tau ua ua ntej rau kev xaiv cov khoom. Azo molecules muaj qee qhov polarity thiab tshwj xeeb spatial configuration. Cov khoom siv uas tau xaiv yuav tsum tsim kom muaj kev sib raug zoo nrog lawv ntawm qib molecular, tsis txhob sib sau ua ke, nag lossis daus, los yog kev sib tshuam ntawm lub ntsej muag. Rau cov txheej txheem kev daws teeb meem, cov tsis muaj solubility ntawm cov substrate los yog polymer yuav tsum phim qhov hnyav ib puag ncig ntawm azo compound kom txo tau qhov kev ua tau zoo ntawm kev hloov kho qhov muag los ntawm qhov tsis sib xws. Hauv cov khoom siv polymer sib xyaw lossis ntoo khaub lig- cov kab ke sib txuas, cov khoom sib txuas nrog kev sib raug zoo nrog azo molecular chains yuav tsum yog qhov tseem ceeb. Interfacial bonding yog txhim kho los ntawm hydrogen bonding, π-π stacking, los yog van der Waals rog, yog li tuav ntev -lub sij hawm stability ntawm lub photoresponse muaj nuj nqi.
Stability yog lwm qhov taw qhia tseem ceeb. Txij li cov pab pawg azo muaj kev cuam tshuam rau isomerization lossis degradation nyob rau hauv lub zog ntawm lub teeb, tshav kub, thiab oxygen, cov khoom yuav tsum muaj cov khoom thaiv thiab kev tiv thaiv. Piv txwv li, hauv kev siv kho qhov muag, iav lossis pob tshab polymers nrog lub teeb xa hluav taws xob siab thiab kev ua haujlwm zoo UV tiv thaiv tuaj yeem raug xaiv los txo qis kev ua haujlwm degradation los ntawm lub teeb raug. Rau cov khoom ua haujlwm nyob rau hauv siab - qhov kub thiab txias ib puag ncig, matrix nrog cov cua sov zoo thiab qhov sib piv ntawm thermal expansion yuav tsum raug xaiv los tiv thaiv thermal stress los ntawm cuam tshuam kev txiav txim ntawm azo molecules. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv cov pa oxygen permeation, txheej txheej zaj duab xis los yog cov tshuaj tiv thaiv antioxidant tuaj yeem nkag mus rau hauv cov khoom siv.
Cov txheej txheem compatibility kuj tseem ceeb heev. Cov txheej txheem molding sib txawv muaj cov kev cai tshwj xeeb rau cov khoom siv rheological, kho tus cwj pwm, thiab kev sib tshuam ntawm cov khoom siv. Rau yaj ua, polymers nrog zoo thermal stability thiab nruab nrab yaj flowability yuav tsum tau xaiv kom tsis txhob azo pawg decomposition ntawm kub. Kev daws txheej yuav tsum tau xav txog cov tshuaj inertness ntawm cov kuab tshuaj thiab cov khoom siv los tiv thaiv o los yog corrosion ua rau cov yam ntxwv tsis xws luag. Hauv cov ntawv thov uas xav tau micro/nano patterning, cov khoom yuav tsum muaj cov khoom tsim tau zoo thiab qhov ruaj khov kom ntseeg tau siab - qauv kev ncaj ncees thaum lub sij hawm photomasking lossis imprinting.
Tsis tas li ntawd, kev xaiv cov khoom siv yuav tsum ua tib zoo ua raws li cov hom phiaj ntawm daim ntawv thov. Rau cov khoom siv tau yooj yim hnav, yuav tsum tau hais txog qhov yooj thiab ua pa; Rau kev siv raws li tus neeg nqa khoom hauv cov kab ke lom neeg, biocompatibility thiab biodegradability yuav tsum raug txiav txim siab, ua kom muaj kev tswj hwm ntawm azo molecules nyob rau hauv ib puag ncig physiological.
Hauv cov ntsiab lus, kev xaiv cov khoom siv azo compound yuav tsum muaj kev ntsuam xyuas kev sib raug zoo, kev ruaj ntseg, kev ua kom haum, thiab kev ua haujlwm. Los ntawm kev sib koom ua ke ntawm cov molecule thiab matrix, qhov kev pom zoo sib npaug ntawm kev ua tau zoo, kev ua haujlwm ntev, thiab kev ua tau zoo tuaj yeem ua tiav, tso lub hauv paus rau kev siv txhim khu kev qha hauv ntau qhov chaw.
