Cov kws tshawb fawb thoob ntiaj teb tab tom sim txhim kho lub cev thiab lub zog ntawm ntoo thiab nws cov khoom sib txuas. Ib pab neeg tshawb fawb ntawm Royal Institute of Technology hauv Stockholm nyuam qhuav luam tawm lawv txoj kev tshawb fawb txog qhov teeb meem no. Hauv chav kuaj mob, lawv tau tswj los tsim cellulose nanofiber, uas yog tsis qis dua hauv lub zog rau cov ntaub ntawv zoo li hauv kev thov hauv kev tsim kho xws li steel, ceramics thiab fiberglass Tsis tas li ntawd, tus qauv kawg yog yim lub sij hawm muaj zog dua li cov xov kab laug sab, cov txheej txheem kub ntawm lub teeb huab roj.
Cellulose nanofibers (lawv kuj yog nanofibrils) yog cov khoom me tshaj plaws nyob rau hauv cov qauv ntawm cov nroj tsuag hlwb, uas muaj qhov xav tsis thoob lub zog loj thiab cov tawv ncauj qhia rau cov kab mob nyob. Nws tsis yog qhov ceeb tias kev txaus siab tshawb fawb hauv nanofibrils tseem yog qhov xwm yeem. Txawm li cas los xij, kev hloov pauv ntawm cov khoom tau hais los ntawm cov nanoparticles rau macrolevel "tsis poob zoo" tseem yog ib txoj haujlwm nyuaj kom txog thaum tam sim no: thaum muaj kev sib luag, cov qauv tsis xws luag tau tshwm sim, uas txo qhov zoo ntawm cov khoom kawg. Pab neeg tshawb fawb ntawm Royal Institute of Technology tswj kom kov yeej qhov teeb meem no nrog kev pab ntawm dej deionized, uas hloov cov qauv ntawm cov nanofibers thiab "ua ke" lawv nyob rau hauv ib qho kev taw qhia, uas ua rau cov khoom siv pib ntau dua. Raws li qhov tshwm sim ntawm cov tshuaj lom neeg no, lub elasticity ntawm tus qauv yog 86 gigapascals, thiab lub zog qhov kawg yog 1.57 gigapascals. Cov kws tshawb nrhiav tau hais tias qhov kev tshawb pom tau tuaj yeem siv rau hauv kev tsim kho, tsheb thiab tshuaj.
