Nanocellulose yog cov khoom siv biomass ntau tshaj plaws hauv ntiaj teb. Nws muaj qhov zoo ntawm qhov yooj yim degradation, rov ua dua tshiab, tsis muaj tshuaj lom thiab pheej yig thiab yooj yim kom tau txais. Nws yuav tsum tau hloov cov khoom siv petrochemical ib txwm siv thiab siv los tsim ntau yam khoom siv ua haujlwm siab heev nrog tus nqi ntxiv. Raws li kev npaj thiab cov chaw ntawm nanocelluloses, nanocelluloses tuaj yeem muab faib ua peb pawg: cellulose nanocrystalline (CNC), cellulose nanofiber (CNF) thiab kab mob cellulose (BC).

Nanocellulose ua haujlwm cov ntaub ntawv rau chiral photonics

Chirality yog ubiquitous nyob rau hauv cov xwm thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv lub neej science thiab cov ntaub ntawv science. CNC yog ib hom nano-scale chiral photonic siv lead ua khoom. Lub chiral nematic kua siv lead ua theem qauv ntawm CNC tsis tsuas yog siv los npaj cov khoom siv ua haujlwm nrog cov khoom siv kho qhov muag siab thiab cov khoom siv kho qhov muag tshwj xeeb, tab sis kuj tuaj yeem siv los ua cov qauv muag muag los ntxias nanoparticles los tsim cov khoom siv nrog cov qauv chiral. Yog li ntawd, chiral catalysis, chiral metamaterials, polarization encryption thiab biosensing muaj cov ntawv thov tseem ceeb.

Nanocellulose ua haujlwm cov ntaub ntawv rau software tsav tsheb

Nyob rau hauv xyoo tas los no, raws li ntau yam ntaub ntawv mos tau los ntawm cov khoom siv hluavtaws, xws li cov hydrogels, kua siv lead ua elastomers thiab cov duab nco polymers, cov kws tshawb fawb tau ntse tsim ntau yam ntawm biomimetic ntse actuators los ua kom zoo li lossis ntau tshaj qhov kev tsav tsheb ntawm cov kab mob. Txawm li cas los xij, cov khoom siv polymer-raws li niaj hnub no feem ntau yog tsim los ntawm cov txheej txheem nyuaj, raug nqi thiab nyuaj rau degrade los yog rov ua dua tshiab, uas yuav ua rau muaj kev cuam tshuam rau ib puag ncig. Nws yog ib qho tsim nyog sau cia tias biomimetic software actuators raws li nanocellulose tau nyiam ntau dua thiab ntau dua vim lawv cov khoom siv tau yooj yim dua, muaj peev xwm hygroscopic siab, ruaj khov lossis eco-phooj ywg, rov siv tau lossis biodegradable, thiab biocompatibility.

Nanocellulose ua haujlwm cov ntaub ntawv rau lub zog cia

Vim hais tias ntawm nws qhov loj tshwj xeeb thaj chaw, zoo heev mechanical yooj, zoo tshuaj stability thiab ib puag ncig tus phooj ywg, raws li zoo raws li interlacing ntawm fibers, nanocellulose yog ib qho yooj yim los tsim ib tug ntxeem tau qauv uas pab ion thiab electron thauj. Hydrophilic functional pawg xws li hydroxyl thiab carboxyl pawg tau txuas rau saum npoo ntawm cov fiber ntau, thiab nws muaj peev xwm moisturizing zoo hauv cov tshuaj electrolyte, uas ua rau cov khoom siv tau los muaj kev cia siab dav hauv thaj chaw ntawm lub zog cia. Nanocellulose raws li cov khoom siv tsis tuaj yeem tsuas yog siv los ua cov khoom siv hauv cov khoom siv hluav taws xob, xws li daim nyias nyias, electrolytes, nplaum thiab cov khoom nqa. Nyob rau tib lub sijhawm, kub kub carbonization, nyob rau hauv cov tshuaj polymerization thiab electrochemical deposition yuav siv tau los compound electroactive cov ntaub ntawv kom tau finer nanostructures thiab zoo heev electrochemical zog.

Nanocellulose cov ntaub ntawv ua haujlwm rau kev siv biomedical

Nyob rau hauv lub xeev qhuav, lub zog txhua yam ntawm nanocellulose yog piv rau tib neeg cov pob txha, thaum nyob rau hauv lub xeev ntub, lub physicochemical zog ntawm nanocellulose zoo ib yam li cov extracellular matrix. Nyob rau tib lub sijhawm, ntxiv rau cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, nanocelluloses muaj kev sib raug zoo nrog lwm cov polymers lossis cov khoom siv ua haujlwm, uas ua rau nanocelluloses raws li cov khoom siv muaj txiaj ntsig zoo thiab siv dav hauv kev lag luam biomedical.
