N-Isopropylacrylamide CAS 2210-25-5
ʻO N-Isopropylacrylamide (N-isopropylacrylamide) he paʻa keʻokeʻo keʻokeʻo ma ka lumi wela a me ke kaomi. Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia me nā mea hoʻoheheʻe kūlohelohe maʻamau. Aia i loko o ka mea waiwai kahi paʻa pālua i hoʻololi ʻia i loko o kona ʻano molekala, hiki ke hoʻohana ʻia ma ke ʻano he polymer monomer a hoʻohana nui ʻia e kūkulu i ka polymer. ʻO N-isopropylacrylamide kekahi pūhui monomer biocompatible i hiki ke hoʻohana ʻia e hana i nā polymers stimulus-responsive ma muli o kona mau ʻano wela, me ka nui a me nā loli wela.

ʻO N-isopropylacrylamide kahi monomer derivative acrylamide. Ma muli o ka loaʻa ʻana o ka hui hydrophilic amide a me ka pūʻulu isopropyl hydrophobic i loko o ka mole, ʻo kona homopolymer he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me nā ʻano maikaʻi ʻē aʻe. Hoʻohana nui ʻia ia i ka hana ʻana i nā gels polymer wela, e like me: nā mea hoʻokuʻu i ka lāʻau lapaʻau, nā mea paʻa enzyme, nā mea dehydrating, concentrating agents, etc. a pela aku. Hoʻohana ʻia ka N-isopropylacrylamide no ka hoʻomākaukau ʻana i ka poly (N-isopropylacrylamide) (pNIPA, pNIPAAm, pNIPAm) nā polymers sensitive wela a i ʻole copolymer hydrogels. ʻO nā polymers i loaʻa ka NIPAM e emi loa i ka mahana ma luna o 33°C. Hoʻohana ʻia ka monomer no ka hoʻomākaukau ʻana i nā hydrogels hiki ke hoʻonui i ka wela.
