Imikhiqizo

I-2,2,2-Trifluoroethyl methacrylate, eyaziwa nangokuthi i-TFEMA, i-monomer ethola izinhlelo zokusebenza ezihlukene emkhakheni wesayensi ye-polymer nobunjiniyela bezinto.I-TFEMA iyinhlanganisela ye-ester eyingxenye yomndeni wama-methacrylates, asetshenziswa kakhulu ekuhlanganiseni ama-polymer ahlukahlukene kanye nama-copolymers.Okunye ukusetshenziswa okuyinhloko kwe-TFEMA ekudaleni ama-polymers asebenza kahle kakhulu.I-TFEMA ingakwazi ukwenza i-polymerization ngokusebenzisa amasu e-free-radical polymerization ukuze ikhiqize ama-polymer anezakhiwo ezifiselekayo.Lawa ma-polymer abonisa ukuzinza okuhle kakhulu kokushisa, ukumelana namakhemikhali, namandla emishini, okuwenza afanelekele ukusetshenziswa kuma-coatings, anamathelayo, namapulasitiki obunjiniyela.Isakhiwo samakhemikhali esiyingqayizivele se-TFEMA, neqembu layo le-trifluoroethyl kanye ne-methacrylate moiety, kunikeza ukusebenza okwengeziwe kanye nezakhiwo ama-polymers avelayo.Iqembu le-trifluoroethyl linomthelela ekuzinzeni okuthuthukisiwe kokushisa nokumelana namakhemikhali, kuyilapho iqembu le-methacrylate lenza ukukhohliswa okulula kwenqubo ye-polymerization, okuvumela ukulawula phezu kwesisindo samangqamuzana nokuqina kokuxhumanisa.TFEMA ingaphinda ifakwe kuma-copolymers ukuze kuthuthukiswe izici zabo.Ngokuhlanganisa i-TFEMA namanye ama-monomers, afana ne-methyl methacrylate noma i-styrene, izinto ezisetshenziswayo ezingaba khona zingabonisa inhlanganisela yezakhiwo ezivela womabili ama-monomers.Lokhu kuguquguquka kuvumela ukuthungwa kwama-copolymer anezici ezithile, njengokunwebeka kokuguquguquka, ukunamathela okuthuthukisiwe, noma ukucaca okubonakalayo okuthuthukisiwe.Okunye ukusetshenziswa kwe-TFEMA kusekusetshenzisweni kwayo njengesithasiselo esisebenzayo ezinhlelweni ezihlukahlukene.I-TFEMA ingasetshenziswa ngokuhlanganyela namanye ama-monomers noma ama-oligomers ukuze kulungiswe izakhiwo zabo noma ukwethule imisebenzi ethile.Isibonelo, i-TFEMA ingasetshenziswa njenge-ejenti exhumanisayo ezinhlelweni ezilapheka yi-UV, ehlinzeka ukuqina okuthuthukisiwe kanye nokumelana namakhemikhali kanye nesimo sezulu.TFEMA iphinda isetshenziswe emkhakheni wokuguqulwa kwe-polymer surface.Ngenxa yesakhiwo sayo samakhemikhali esiyingqayizivele, i-TFEMA inganamathiselwa kalula ebusweni bezinto ngokusebenzisa amasu afana nokuxhunyelelwa noma ukunamathela.Lokhu kuguqulwa kwendawo kunganikeza izici ezifana ne-hydrophobicity, ukusebenza okuvimbela ukungcola, noma ukunamathela okuthuthukisiwe.Kafushane, i-2,2,2-Trifluoroethyl methacrylate (TFEMA) iyi-monomer eguquguqukayo ethola izinhlelo zokusebenza ku-polymer synthesis, copolymerization, izithasiselo ezisebenzayo, kanye ukuguqulwa kwendawo.Ama-polymers avelayo kanye nama-copolymers abonisa izakhiwo ezinjengokuqina kokushisa, ukumelana namakhemikhali, amandla emishini, nezici ezivumelanisiwe.Ukusetshenziswa kwayo okuhlukahlukene kwenza i-TFEMA ibe ithuluzi elibalulekile ekuthuthukisweni kwezinto ezisebenza kahle kakhulu zohlu lwezimboni, okuhlanganisa okokunamathela, okokunamathelisa, amapulasitiki, kanye nezicelo zokulungiswa kwendawo.
