Kev Tshawb Fawb Txog Txhim Kho Cov Av qias neeg

Cov pa phem hauv av yog qhov teeb meem loj uas tau sib tham txog nyob rau niaj hnub no. Nyob rau lub sijhawm tam sim no, Tebchaws Asmeskas tau tshaj tawm cov nanoparticle technology, qhov chaw nruab nrab ntawm qhov me me yog cov tub ntxhais hlau thiab sab nraud yog them los ntawm multilayer polymer. Ntawm lawv, sab hauv txheej yog them nrog poly methl methacrylate (PMMA), uas muaj cov dej tsis qab zoo, thiab txheej txheej sab nraud yog them nrog hydrophilic sulphonated polystyrene. Txij li cov hydrophilic txheej txheej ua rau cov nanoparticles yaj hauv dej, sab hauv txheej txheej dej tsis muaj peev xwm tuaj yeem nyiam cov pa phem los ntawm trichlorethylene (trichlorethylene). Cov hlau tub ntxhais hauv cov nanoparticles ua rau lub trichlorethylene los sib cais, uas ua rau cov pa phem no maj mam muab faib ua cov khoom tsis muaj tshuaj lom.
