Cov kua dej ua haujlwm yog cov kua tshwj xeeb nrog cov tshuaj, tshuaj lom neeg, lossis roj ntsha. Lawv tau tsim los ua kom tau raws li cov kev xav tau ntawm cov ntawv thov tshwj xeeb, tsis yog kev pab raws li cov kuab tshuaj lossis xov xwm hauv kev nkag siab. Cov kua dej no, npaj los ntawm cov qauv molecular tsim qauv, kev ua kom zoo dua, lossis ua kom muaj lub luag haujlwm tseem ceeb hauv kev lag luam, kev tiv thaiv kev noj qab haus huv, kev tiv thaiv ib puag ncig, thiab ib puag ncig.
Los ntawm kev txhais, cov yam ntxwv tseem ceeb ntawm cov dej ua kom dej nyob hauv lawv txoj kev "ua haujlwm." Piv txwv li, ntxiv cov nanoparticles kom cov roj nplua nyeem tuaj yeem txo qis kev sib txhuam thiab txuas ntxiv rau kev ua haujlwm; tshuab hluav taws xob txhim kho cua sov disspation los ntawm siab thermal conductivity; Thiab cov kua dej haus biocompe tau siv rau hauv kev xa tshuaj lossis cov ntaub so ntswg, kom muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg. Raws li hom kev ua tiav, cov kua dej ua haujlwm tau tuaj yeem faib ua peb hom hluav taws xob, tshuaj lom neeg (piv txwv li (piv txwv li, antimicrobial thiab kho).
Ntawm daim ntawv thov, tus nqi ntawm cov kua dej ua haujlwm nyob hauv lawv cov kev daws teeb meem. Cov hauj lwm muaj nyob rau ntawm high {}}}}}} kev lag luam tshiab iones kom kho cov roj teeb ua kom zoo. Hauv kev siv tshuaj kho mob, cov kua dej ua haujlwm tau siv rau kev npaj tshuaj lossis hauv kev txhim kho hauv cov tshuaj vitro kuaj mob. Tsis tas li ntawd, cov kua dej ib puag ncig ua kua (xws li maj mam hloov cov kua dej (cov khoom siv qias neeg, ua kom cov kev xav tau ntawm kev txhim kho kom ruaj khov.
Technically, cov kev tshawb fawb thiab kev txhim kho cov kua ua kom muaj kev sib tshuam ntawm ntau txoj kev sib tshuam, suav nrog cov ntaub ntawv science, kev siv roj. The introduction of cutting-edge techniques such as nanotechnology and molecular self-assembly has further expanded the boundaries of their performance. Nyob rau hauv lub neej yav tom ntej, raws li cov qauv ntawm kev txawj ntse thiab ntsuab kev sib xyaw ua ke, kev hloov kho kom muaj ntau zog, thiab ua kom muaj peev xwm txhawb nqa kev sib xyaw ua ke thiab txiav {{} ntug thev naus laus zis.
