N-Isopropylacrylamide CAS 2210-25-5
N-Isopropylacrylamide (N-isopropylacrylamide) ndi crystalline yoyera yolimba kutentha ndi kupanikizika. Imasungunuka m'madzi ndipo imasakanikirana ndi zosungunulira za organic. Zinthuzo zimakhala ndi chomangira chimodzi cholowetsedwa m'malo mwake, chomwe chimagwiritsidwa ntchito ngati polima monomer ndipo chimagwiritsidwa ntchito kwambiri popanga polima. N-isopropylacrylamide ndi biocompatible monomer unit yomwe ingagwiritsidwe ntchito kupanga ma polima okhudzidwa ndi kutentha chifukwa cha kutentha kwake, kuphatikizapo voliyumu ndi kusintha kwa kutentha.

N-isopropylacrylamide ndi monomer yochokera ku acrylamide. Chifukwa cha kukhalapo kwa gulu la hydrophilic amide ndi gulu la hydrophobic isopropyl mu molekyulu, homopolymer yake imakhala ndi kutentha kotsika kofunikira komanso mawonekedwe ena abwino. Amagwiritsidwa ntchito kwambiri popanga ma gels osagwirizana ndi kutentha kwa polima, monga: zida zoyendetsedwa ndi mankhwala osokoneza bongo, zida zolimba za enzyme, othandizira ochotsa madzi m'thupi, othandizira, etc. Itha kugwiritsidwanso ntchito popanga mphira wa denatured Chemicalbook mkaka, zokutira zapadera, zomatira. ndi zina zotero. N-isopropylacrylamide imagwiritsidwa ntchito popanga poly (N-isopropylacrylamide) (pNIPA, pNIPAAm, pNIPAm) ma polima ozindikira kutentha kapena ma hydrogel a copolymer. Ma polima okhala ndi NIPAM amachepa kwambiri pakatentha kuposa 33°C. Monomer imagwiritsidwa ntchito popanga ma hydrogel osamva kutentha, owonjezera madzi.
