Daim Ntawv Thov

1. Cov polymers supramolecular yog hais txog cov polymers uas tau sib sau ua ke los ntawm cov monomers me me lossis cov polymers molecular qis los ntawm kev sib cuam tshuam tsis sib xws. Cov yam xws li pH, kub thiab lub teeb tuaj yeem ua rau muaj kev sib cais thiab rov ua dua ntawm cov ntawv cog lus tsis sib xws ntawm cov polymers supramolecular, uas yog rov qab tau. Yog li ntawd, cov polymers supramolecular yog cov khoom siv ntse uas tuaj yeem siv los kho tus kheej thiab kho tus kheej. Ib qho ntawm cov chaw tshawb fawb hauv tsev thiab txawv teb chaws hauv xyoo tas los no. Cov polymers supramolecular muaj ntau yam kev siv, xws li cov khoom siv ntse hloov kho, cov khoom siv hluav taws xob thiab cov khoom siv biological. Hauv xyoo tas los no, nws cov kev tshawb fawb siv hauv biological thiab biomedical teb tau tsim kho sai, suav nrog cov ntawv thov ntsig txog cell, kev tsim cov ntaub so ntswg, thiab lwm yam.

1,3-bis(1-methylvinyl)benzene siv tau los npaj ib lub polymer supramolecular raws li nram no:

Muab 10g lipoic acid hmoov rau hauv lub reactor uas muaj lub cuab yeej sib tov, ua kom sov lub roj da dej kom txog thaum cov hmoov lipoic acid yaj, thiab pib sib tov. Tom qab ntawd ntxiv 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) rau hauv lub reactor, thiab txuas ntxiv ua kom sov thiab sib tov rau 5 feeb. Tom qab ntawd ntxiv 0.1g ntawm ferric chloride acetone kua rau hauv lub reactor, txuas ntxiv ua kom sov thiab sib tov rau 3 feeb, tsum tsis txhob ua kom sov, thiab txias rau qhov kub thiab txias hauv chav kom tau txais supramolecular polymer-1.

2.1,3-Di(1-methylvinyl)benzene siv tau los npaj txoj kev hloov kho ntawm polyvinyl chloride tshwj xeeb resin. Lub zog ntawm cov khoom siv PVC polymer hauv txoj kev no feem ntau nyob ntawm lub zog sib txuas tshuaj thiab cov molecules ntawm cov saw hlau tseem ceeb. Lub luag haujlwm ntawm cov ntawv cog lus thib ob ntawm 15 hom kev sib txuas lus yog siv los npaj cov khoom siv tshwj xeeb PVC tshiab. Cov neeg sawv cev sib txuas lus no muaj cov pab pawg ua haujlwm tshwj xeeb, xws li cov ntawv cog lus sib txuas ob npaug, pawg phenyl, thiab pawg heterocyclic. Kev qhia txog cov pab pawg no Nws tuaj yeem ua rau muaj kev cuam tshuam steric ntawm cov saw hlau polymer molecular. Tib lub sijhawm, cov pab pawg ionic, pawg polar lossis hydrogen bonds tsim tuaj yeem txhim kho lub zog ntawm cov khoom siv PVC polymer. Los ntawm kev siv tus neeg sawv cev sib txuas lus nrog cov qauv tshwj xeeb, qhov kev tsim kho tshiab no qhia txog cov qauv sib txuas lus tshwj xeeb rau hauv PVC macromolecular saw hlau, hloov nws los ntawm cov qauv linear mus rau cov qauv hauv zos. Qhov kev hloov pauv qauv no tuaj yeem txhim kho zoo heev Kev tiv thaiv cua sov ntawm PVC tuaj yeem txo qhov thermal shrinkage thiab txhim kho nws cov kev ua tau zoo, yog li ntawd nthuav dav ntxiv cov xwm txheej ntawm daim ntawv thov ntawm PVC. Los ntawm kev hloov kho qhov sib txuas, cov saw hlau polyvinyl chloride tuaj yeem sib txuas ua ke kom raug, yog li cov polymer muaj cov khoom zoo ntawm polyvinyl chloride thiab cov khoom hloov kho. Cov neeg sawv cev sib txuas no tsis tsuas yog siv tau rau hauv cov polymerization siab PVC resins thiab matte Nws kuj siv rau hauv PVC resin. Tib lub sijhawm, nws kuj muaj peev xwm siv tau rau hauv kev hloov kho qhov sib txuas ntawm lwm cov PVC tshwj xeeb resins, xws li PVC paste resin, chlorine-vinegar resin, qib polymerization qis / ultra-low PVC, polyvinylidene chloride, CPVC, thiab lwm yam.
