N-Isopropylacrylamide CAS 2210-25-5
N-Isopropylacrylamide (N-isopropylacrylamide) waa crystalline cad oo adag heerkulka qolka iyo cadaadiska. Waxay ku milmi kartaa biyaha waxayna ku dhex milmi kartaa dareerayaasha dabiiciga ah ee caadiga ah. Walaxda waxa ay ka kooban tahay hal xidhid oo labanlaaban oo la beddeley oo ah qaab dhismeedkeeda molecular, kaas oo loo isticmaali karo monomer polymer ah oo inta badan loo isticmaalo in lagu dhiso polymer. N-isopropylacrylamide sidoo kale waa unug monomer ah oo ku habboon oo loo isticmaali karo in lagu sameeyo polymers-ka-jawaab-kicinta sababtoo ah sifooyinka heerkulka-xasaasiga ah, oo ay ku jiraan mugga iyo isbeddellada heerkulka.

N-isopropylacrylamide waa monomer ka soo jeeda acrylamide. Sababtoo ah joogitaanka kooxda amide hydrophilic iyo kooxda isopropyl hydrophobic ee molecule, homopolymerkeeda waxay leedahay heerkulka xalinta hoose ee muhiimka ah iyo sifooyin kale oo wanaagsan. Waxaa inta badan loo isticmaalaa soo saarista jel polymer-xasaasi ah, sida: alaabta lagu sii daayo daroogada la xakameeyey, walxaha adag ensaymes, wakiilada fuuqbaxa, wakiilada xoogga saaraya, iwm. Waxa kale oo loo isticmaali karaa in lagu soo saaro caag denatured caanahabook Chemicalbook, dahaarka gaarka ah, xabagta. iyo wixi la mida. N-isopropylacrylamide waxaa loo isticmaalaa in lagu diyaariyo poly (N-isopropylacrylamide) (pNIPA, pNIPAAm, pNIPAm) polymers xasaasiga ah kulaylka ama koopolymer hydrogels. Polymers-ka ay ku jiraan NIPAM waxay si aad ah u yareeyaan heerkul ka sarreeya 33°C. monomer-ka waxa loo isticmaalaa in lagu diyaariyo kulaylka xasaasiga ah, biyo-ballaadhinta hydrogels.
