1. Supramolecular polymers xa mus rau cov polymers nws tus kheej sib dhos los ntawm cov me me molecular monomers los yog tsawg molecular polymers los ntawm non-covalent daim ntawv cog lus. Cov yam ntxwv xws li pH, kub thiab lub teeb tuaj yeem ua rau kev sib cais thiab rov ua haujlwm ntawm cov tsis-covalent bonds ntawm supramolecular polymers, uas yog thim rov qab. Yog li, supramolecular polymers yog cov khoom ntse uas tuaj yeem siv los kho tus kheej thiab kho tus kheej. Ib qho ntawm cov kev tshawb fawb hotspots hauv tsev thiab txawv teb chaws hauv xyoo tas los no. Supramolecular polymers muaj ntau yam kev siv, xws li hloov kho cov khoom ntse, cov khoom siv hluav taws xob thiab cov khoom siv roj ntsha. Nyob rau hauv xyoo tas los no, nws cov kev tshawb fawb siv nyob rau hauv biomedical thiab biomedical teb tau tsim sai heev, nrog rau cov kev siv ntawm tes, ntaub so ntswg engineering, thiab lwm yam.
1,3-bis (1-methylvinyl) benzene tuaj yeem siv los npaj cov supramolecular polymer raws li hauv qab no:
Muab 10g lipoic acid hmoov nyob rau hauv lub reactor nruab nrog ib tug stirring ntaus ntawv, sov lub roj da dej kom txog thaum lub lipoic acid hmoov melts, thiab pib stirring. Tom qab ntawd ntxiv 6g (60wt%) 1,3-bis (1-methylvinyl) benzene (DIB) rau hauv lub reactor, thiab txuas ntxiv cua sov thiab nplawm rau 5 feeb. Tom qab ntawd ntxiv 0.1g ntawm ferric chloride acetone tov rau hauv lub reactor, txuas ntxiv cua sov thiab stirring rau 3 feeb, nres cua sov, thiab txias rau chav tsev kub kom tau supramolecular polymer-1.
2.1,3-Di (1-methylvinyl) benzene tuaj yeem siv los npaj kev hloov pauv kev sib txuas ntawm polyvinyl chloride tshwj xeeb cob. Lub zog ntawm PVC cov ntaub ntawv polymer nyob rau hauv txoj kev no feem ntau yog nyob ntawm cov tshuaj sib khi quab yuam thiab molecules ntawm cov saw tseem ceeb. Lub luag haujlwm ntawm cov ntawv cog lus thib ob ntawm 15 hom kev sib txuas sib txuas yog siv los npaj PVC tshwj xeeb resins tshiab. Cov kab txuas txuas txuas no muaj cov pab pawg ua haujlwm tshwj xeeb, xws li kev sib koom ua ke ob daim ntawv cog lus, pawg phenyl, thiab pawg heterocyclic. Kev taw qhia ntawm cov pab pawg no Nws tuaj yeem ua rau muaj kev cuam tshuam tsis zoo ntawm cov saw hlau polymer molecular. Nyob rau tib lub sijhawm, cov pab pawg ionic qhia, 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 nrog cov qauv tshwj xeeb, qhov kev tsim kho tam sim no qhia txog cov qauv sib txuas sib txuas rau hauv PVC macromolecular saw, hloov nws los ntawm cov qauv kab mus rau cov qauv hauv zos. Qhov kev hloov pauv ntawm cov qauv no tuaj yeem txhim kho tau zoo Cov cua sov ntawm PVC tuaj yeem txo cov thermal shrinkage thiab txhim kho nws cov kev ua tau zoo, yog li txuas ntxiv nthuav dav daim ntawv thov scenarios ntawm PVC. Los ntawm kev hloov pauv kev sib txuas, polyvinyl chloride molecular saw tuaj yeem tsim nyog ib feem ntawm kev sib txuas, kom cov polymer muaj cov khoom zoo ntawm polyvinyl chloride thiab cov khoom hloov kho. Cov kab txuas txuas txuas no tsis tuaj yeem tsuas yog siv hauv high-polymerization PVC resins thiab matte Nws yog siv hauv PVC cob. Nyob rau tib lub sijhawm, nws tseem muaj peev xwm siv tau hauv kev sib txuas sib txuas ntawm lwm cov PVC tshwj xeeb resins, xws li PVC paste resin, chlorine-vinegar resin, low / ultra-low polymerization degree PVC, polyvinylidene chloride, CPVC, thiab lwm yam.
Khoom siv: 25kg, 20kg, 10kg, 5kg fiber nruas, PP hnab, craft paper bag, 1kg, 500g, 200g, 100g, 50g, 20g Aluminium foil bag. Carton: yas qhwv thawv. (Lub pob tuaj yeem ua raws li cov neeg siv khoom xav tau.)
