3D Printing:
Cellulose filaments, muab tau los ntawm cov ntoo pulp lossis lwm qhov chaw cellulose, yog siv los ua khoom noj rau 3D luam ntawv.
Lub biodegradability, rov ua dua tshiab, thiab tsis tshua muaj tshuaj lom ntawm cellulose filaments ua rau lawv txaus nyiam rau kev tsim khoom lag luam.
Zog Cia Devices:
Cellulose-raws li cov ntaub ntawv raug soj ntsuam rau siv nyob rau hauv lub zog cia khoom xws li supercapacitors thiab roj teeb.
Cellulose-derived carbon cov ntaub ntawv qhia tau hais tias muaj zog electrochemical zog, nrog rau qhov chaw siab, zoo hluav taws xob conductivity, thiab mechanical robustness.
Biomedical Applications:
Cellulose scaffolds yog siv hauv cov ntaub so ntswg engineering rau kev siv tshuaj kho dua tshiab.
Biodegradable cellulose-raws li cov khoom siv ua cov tshuaj xa khoom, kev hnav khaub ncaws kho mob, thiab scaffolds rau kab lis kev cai ntawm tes thiab cov ntaub so ntswg.
Kev kho dej:
Cellulose-based adsorbents yog ua haujlwm rau kev lim dej thiab kev kho dej khib nyiab.
Hloov kho cov ntaub ntawv cellulose zoo tshem tawm cov kab mob xws li cov hlau hnyav, dyes, thiab cov kuab tshuaj organic los ntawm cov tshuaj aqueous los ntawm cov txheej txheem adsorption.
Electronics thiab Optoelectronics:
Transparent conductive films thiab substrates ua los ntawm cellulose nanocrystals raug soj ntsuam rau siv nyob rau hauv saj zawg zog electronics thiab optoelectronic li.
Cellulose-raws li cov ntaub ntawv muaj txiaj ntsig zoo xws li pob tshab, hloov tau yooj yim, thiab kev ruaj ntseg piv rau cov khoom siv hluav taws xob.
Yav tom ntej Prospects:
Bioplastics:
Cellulose-based bioplastics tuav cov lus cog tseg raws li kev hloov pauv mus rau cov pa roj av raws li cov yas.
Kev siv zog tab tom tsim los tsim cov cellulose-derived polymers nrog cov khoom siv kho kom zoo dua qub, biodegradability, thiab kev ua cov yam ntxwv rau kev siv dav hauv ntim khoom, cov khoom siv, thiab kev siv tsheb.
