2,2,2-Trifluoroethyl methacrylate, yomwe imadziwikanso kuti TFEMA, ndi monomer yomwe imapeza ntchito zosiyanasiyana m'munda wa sayansi ya polima ndi uinjiniya wazinthu.TFEMA ndi gulu la ester lomwe liri m'banja la methacrylates, lomwe limagwiritsidwa ntchito kwambiri popanga ma polima osiyanasiyana ndi ma copolymers.Imodzi mwa ntchito zazikulu za TFEMA ndi kupanga ma polima apamwamba kwambiri.TFEMA itha kuchitidwa ma polymerization kudzera munjira zaufulu-radical polymerization kuti apange ma polima okhala ndi zinthu zofunika.Ma polima awa amawonetsa kukhazikika kwamafuta, kukana kwamankhwala, ndi mphamvu zamakina, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito mu zokutira, zomatira, ndi mapulasitiki aumisiri.Mapangidwe apadera amankhwala a TFEMA, okhala ndi gulu lake la trifluoroethyl ndi methacrylate moiety, amapereka magwiridwe antchito ndi katundu ku chifukwa ma polima.Gulu la trifluoroethyl limathandizira kukhazikika kwamafuta ndi kukana kwa mankhwala, pomwe gulu la methacrylate limathandizira kuwongolera kosavuta kwa ma polymerization, kulola kuwongolera kulemera kwa maselo ndi kachulukidwe kolumikizana.TFEMA imathanso kuphatikizidwa mu ma copolymers kuti apititse patsogolo katundu wawo.Pakuphatikiza TFEMA ndi ma monomers ena, monga methyl methacrylate kapena styrene, zinthu zomwe zatuluka zimatha kuwonetsa kuphatikiza kwazinthu kuchokera ku ma monomers onse awiri.Kuphatikizika kumeneku kumathandizira kukonza ma copolymers okhala ndi mawonekedwe apadera, monga kusinthasintha kowonjezereka, kumamatira bwino, kapena kumveketsa bwino kwa kuwala.Kugwiritsanso ntchito kwina kwa TFEMA kuli pakugwiritsa ntchito kwake ngati chowonjezera chokhazikika pamakina osiyanasiyana.TFEMA itha kugwiritsidwa ntchito limodzi ndi ma monomers ena kapena oligomers kusintha katundu wawo kapena kuyambitsa magwiridwe antchito.Mwachitsanzo, TFEMA ingagwiritsidwe ntchito ngati njira yolumikizirana m'makina ochiritsira a UV, kupereka kukhazikika bwino komanso kukana kwa mankhwala ndi weathering.TFEMA imagwiritsidwanso ntchito pokonza polima pamwamba.Chifukwa cha kapangidwe kake kapadera ka mankhwala, TFEMA imatha kumangika pamwamba pa zinthu mosavuta kudzera munjira monga kumezanitsa kapena zokutira.Kusinthidwa pamwambaku kumatha kupereka zinthu monga hydrophobicity, anti-fouling performance, kapena kumamatira kumawonjezera. kusinthidwa pamwamba.Zotsatira zake ma polima ndi ma copolymers amawonetsa zinthu monga kukhazikika kwamafuta, kukana kwamankhwala, mphamvu zamakina, ndi mawonekedwe ogwirizana.Kugwiritsiridwa ntchito kwake kosiyanasiyana kumapangitsa TFEMA kukhala chida chofunika kwambiri popanga zipangizo zogwira ntchito kwambiri m’mafakitale osiyanasiyana, kuphatikizapo zokutira, zomatira, mapulasitiki, ndi ntchito zosinthira pamwamba.
