N-Isopropylacrylamide CAS 2210-25-5
N-Isopropylacrylamide (N-isopropylacrylamide) yog dawb crystalline khoom ntawm chav tsev kub thiab siab. Nws yog soluble hauv dej thiab miscible nrog cov organic solvents. Cov khoom muaj ib qho kev hloov pauv ob daim ntawv cog lus hauv nws cov qauv molecular, uas tuaj yeem siv los ua cov polymer monomer thiab feem ntau yog siv los tsim cov polymer. N-isopropylacrylamide kuj tseem yog biocompatible monomer unit uas tuaj yeem siv los tsim cov tshuaj tiv thaiv kab mob vim nws cov khoom kub-rhiab, nrog rau ntim thiab qhov kub thiab txias hloov.

N-isopropylacrylamide yog acrylamide derivative monomer. Vim muaj cov hydrophilic amide pawg thiab hydrophobic isopropyl pawg nyob rau hauv lub molecule, nws homopolymer muaj ib tug tsawg tseem ceeb tshuaj kub thiab lwm yam zoo yam ntxwv. Nws yog tsuas yog siv rau hauv kev tsim cov kub-rhiab polymer gels, xws li: tshuaj tswj cov ntaub ntawv tso tawm, enzyme cov ntaub ntawv, dehydrating agents, concentrating agents, thiab lwm yam. Nws kuj yuav siv tau los tsim denatured roj hmab Chemicalbook mis, tshwj xeeb coatings, adhesives. thiab lwm yam. N-isopropylacrylamide yog siv los npaj poly (N-isopropylacrylamide) (pNIPA, pNIPAAm, pNIPAm) kub rhiab heev polymers los yog copolymer hydrogels. Polymers uas muaj NIPAM poob qis ntawm qhov kub siab tshaj 33 ° C. Lub monomer yog siv los npaj cov cua kub-rhiab, dej-expandable hydrogels.
