Nyob rau hauv Grand Toj roob hauv pes niaj hnub, NVP cov ntawv luam tawm tau dhau los ua cov khoom tseem ceeb rau kev txhim kho ntawm ntau kev lag luam vim lawv ua tau zoo heev. Cov polymer polymer no, uas yog polymerized los ntawm n- vinylprolidone (nVP), ua yeeb yam} ua yeeb yam khoom, zoo nkauj, thiab zoo nkauj biocompatibility. Nws yog dav siv hauv cov tshuaj, tshuaj pleev ib ce, khoom noj, kev lag luam, thiab txawm tias txiav - ntug scientific kev tshawb fawb. Los ntawm cov qauv tsim qauv ntawm cov tshuaj muaj zog {}} tso cov khoom siv rau kev txhim kho cov khoom lag luam thiab kev ruaj ntseg hauv cov tshuaj pleev ib yam; Los ntawm kev tsim kho cov ntaub ntawv ntim khoom siv rau kev txhim kho cov khoom lag luam tsim thiab ua tau zoo hauv kev lag luam ntau lawm, NVP cov ntawv luam tawm kev txhim kho ntawm ntau yam kev lag luam.
Cov txheej txheem
NVP copolymers yog chav kawm ntawm polymer tebchaw los ntawm copylates, xws li cov acrylates, thiab lwm yam) li vinyl pyrrolidone (NVP) raws li tus lej Monomer.
Cov tshuaj tiv thaiv copolymerizer tuaj yeem muab ntau yam kev ua ke ntawm cov duab uas muaj peev xwm txhim kho cov khoom siv, thiab cov khoom siv coprente tuaj yeem txhim kho lub zog thiab thermal ruaj khov ntawm cov khoom. Nws yog qhov kev qhia no uas tso cai rau NVP cov ntawv luam tawm tau cov yam ntxwv ntawm NVP ntawm cov khoom ntiag tug xws li tshuaj, tshuaj pleev ib ce, thiab kev lag luam.
Tshuaj lom neeg cov tshuaj lom neeg thiab cov yam ntxwv
Nvp nvp n - vinylprolidone. Nws cov tshuaj lom neeg muaj kuab lom thiab cov yam ntxwv tsim qauv yog lub hauv paus rau kev nkag siab nws ua tau zoo thiab cov haujlwm ntawm cov copolymers. Los ntawm qhov kev pom ntawm cov tshuaj muaj pes tsawg leeg, cov mis molecular ntawm NVP yog c₆h₉no, uas muaj cov pa roj carecen, thiab cov pa roj ntsha ntawm 111.14 g / mol. Nws cov qauv molecular yog nyob rau ntawm lub nplhaib pyrrolidone, thiab cov nitrogen atom ntawm lub nplhaib Vinyl (} letch ch}}
Cov qauv no muab NVP cov yam ntxwv tseem ceeb: txoj kev sib koom ua ke sab nrauv ({0}} l}} Yog li no, nvp monomers thiab polymers synthesized los ntawm lawv feem ntau muaj solubility zoo heev; Thiab cov carbon -} Cov pab pawg ua haujlwm hauv lub Vinyl yog qhov tseem ceeb tshaj plaws cov tshuaj tiv thaiv, uas muab rau Copolymerization nrog lwm tus monomers. Cov khoom ntawm copolymer tuaj yeem hloov tau los ntawm kev kho cov hom thiab faib ntawm cov copolymer monomers. Tsis tas li ntawd, kev ruaj khov ntawm lub nplhaib qauv ua noj nvp thiab nws cov copolymers los tuav cov kev ruaj khov nyob hauv qee qhov kev siv tshuaj lom neeg thiab muaj ob qho tib si biocompatibility. Qhov no tseem yog ib qho laj thawj tseem ceeb vim li cas nws tuaj yeem ua tau dav hauv cov liaj teb nrog cov cai muaj kev nyab xeeb zoo li xws li tshuaj thiab cov tshuaj pleev ib ce.
Cov tub ntxhais kawm ua tau zoo ntawm NVP cov ntawv luam tawm yog cov cim tseem ceeb rau kev ntsuas lawv daim ntawv thov tus nqi thiab kev hloov kho cov xwm txheej. Cov kev txwv no tsis yog tsuas yog nyob ntawm cov yam ntxwv ntawm NVP monomers, tab sis kuj ntawm cov hom, cov txheej txheem polymerization ntawm copolymerized monomers. Lawv tsuas yog npog cov hauv qab no:
· Solubility yog ib qho ntawm cov khoom tseem ceeb ntawm NVP cov tub ntawv luam. Vim yog polar qauv ntawm lub nplhaib pyrrolidone hauv NVP chav tsev, copolymers feem ntau muaj cov dej solubility lossis dej cawv. Los ntawm copolymerizing nrog hydrophobic monomers (xws li cov tshuaj thiab acruber), lawv cov kev sib tw solubines tuaj yeem hloov kho, thiab txawm tias roj} dej amphiphilicity tuaj yeem ua tiav. Tshwj xeeb tsis muaj solubility (g / 100ml cov huab cua (xws li ntsuas qhov sib txawv ntawm cov qauv ntawm cov txheej txheem, cov nplaum, cov khoom npaj, khoom npaj, thiab lwm yam.
· Cua ruaj khov yog cuam tshuam rau qhov kub tsis kam ntawm cov ntsuas cua sov (tga) thiab yog feem ntau ntawm cov ntsuas cua kub (tg) tau los ntawm kev ntsuas calorimetry (DSC). Feem ntau hais lus, kev qhia ntawm cov tub luam yeeb (xws li txiv neej anhydride) tuaj yeem nce tg thiab txhim kho cov khoom siv tiv thaiv kom siab rau siab- kub deformation; Thaum hloov pauv Monomers (xws li vinyl ether) yuav txo tg thiab txhim kho qis qis- kub nruj. Lub thermal decomposition kub feem ntau yuav tsum tau siab dua li kev thov siv kub tiag tiag los ntawm ntau dua 50 degree}}} lub sij hawm ruaj khov ntawm cov khoom muaj kev ua tau zoo.
· Cov khoom siv txhua yam rau cov NVP copolymers (xws li cov yeeb yaj kiab, suav nrog tensile lub zog, elongation ntawm kev tawg, ua kom muaj zog thiab tsev pheeb suab. Piv txwv li, copolymerization nrog Vinyl acetate tuaj yeem txhim kho kev sib raug zoo lub zog thiab yog qhov haum rau cov nplaum teb; Copolymerization nrog Acrylonitrile tuaj yeem txhim kho tensile lub zog thiab ua kom tau raws li cov neeg kho tshuab cov khoom siv. Cov kev ntsuas no yuav tsum tau ntsuas yog tias yog cov cuab yeej xws li cov khoom siv rau cov tshuab sib txawv ntawm cov xwm txheej sib txawv.
· Biocompatibility yog qhov qhia tau tus tseem ceeb ntawm nws daim ntawv thov hauv cov duab thiab cov tshuaj pleev ib ce, thiab lwm yam ntshav, uas yuav tsum tau txheeb xyuas los ntawm ISO 10993 thiab lwm cov txheej txheem ntawm cov kev xeem. Txij li thaum NVP chav tsev nws tus kheej muaj tsawg toxicity, lub biocompatibility ntawm cov copolymer feem ntau yog nyob ntawm kev xaiv ntawm tus neeg ua haujlwm ntawm lub comomoner. Piv txwv li, copolymerization nrog polyethylene glycoling glycole glycole glycole glycole glycole glycole gill txuas ntxiv txhim kho lub hydrophilicity thiab biosafety.
