Kev Tshawb Fawb Tshiab Tshaj Plaws ntawm Carbon Dioxide Polyether Polyols hauv Suav Teb

Cov kws tshawb fawb Suav tau ua tiav ntau yam hauv kev siv cov pa roj carbon dioxide, thiab kev tshawb fawb tshiab qhia tau tias Suav teb yog tus thawj coj hauv kev tshawb fawb txog cov pa roj carbon dioxide polyether polyols.

Cov pa roj carbon dioxide polyether polyols yog ib hom khoom siv biopolymer tshiab uas muaj kev cia siab dav hauv kev ua lag luam, xws li cov ntaub ntawv rwb thaiv tsev, ua npuas dej khawb roj, thiab cov ntaub ntawv biomedical. Nws cov khoom siv tseem ceeb yog carbon dioxide, kev siv cov pa roj carbon dioxide xaiv tau tuaj yeem txo cov pa phem ib puag ncig thiab kev siv hluav taws xob fossil.

Tsis ntev los no, ib pab neeg tshawb fawb los ntawm Department of Chemistry ntawm Fudan University tau ua tiav polymerized cov cawv uas muaj ntau pawg carbonate nrog carbon dioxide los ntawm kev siv cov thev naus laus zis catalytic reaction tsis muaj ntxiv cov stabilizers sab nraud, thiab npaj cov khoom siv polymer siab uas tsis tas yuav kho tom qab. Tib lub sijhawm, cov khoom siv muaj kev ruaj khov thermal zoo, kev ua haujlwm ua tiav, thiab cov khoom siv kho tshuab.

Ntawm qhov tod tes, pab pawg uas coj los ntawm tus kws tshawb fawb Jin Furen kuj tau ua tiav qhov kev sib xyaw ua ke ntawm CO2, propylene oxide, thiab polyether polyols los npaj cov khoom siv polymer siab uas tuaj yeem siv rau kev tsim cov khoom siv rwb thaiv tsev. Cov txiaj ntsig tshawb fawb qhia meej txog qhov ua tau ntawm kev sib xyaw ua ke ntawm kev siv tshuaj lom neeg ntawm carbon dioxide nrog cov tshuaj tiv thaiv polymerization.

Cov txiaj ntsig tshawb fawb no muab cov tswv yim tshiab thiab cov lus qhia rau kev npaj cov thev naus laus zis ntawm cov khoom siv biopolymer hauv Suav teb. Siv cov pa roj pov tseg hauv kev lag luam xws li carbon dioxide los txo cov pa phem ib puag ncig thiab kev siv hluav taws xob fossil, thiab ua kom tag nrho cov txheej txheem ntawm cov khoom siv polymer siab los ntawm cov khoom siv raw mus rau kev npaj "ntsuab" kuj yog qhov sib txawv yav tom ntej.

Xaus lus, Tuam Tshoj txoj kev tshawb fawb ua tiav hauv cov pa roj carbon dioxide polyether polyols yog qhov zoo siab, thiab kev tshawb nrhiav ntxiv yog qhov xav tau yav tom ntej kom ua rau hom khoom siv polymer siab no siv dav hauv kev tsim khoom thiab lub neej.
