求助聚N異丙基丙烯酰胺(PNIPAAm)的玻璃化轉變溫度
|
| 如題,如果能提供可以查找聚合物的玻璃化轉變溫度的網(wǎng)站更好,謝謝! |

Poly(N-isopropylacrylamide) (variously abbreviated PNIPA, PNIPAAm, PNIPAA or PNIPAm) is a temperature-responsive polymer that was first synthesized in the 1950s.[1] It forms a three-dimensional hydrogel when crosslinked with N,N’-methylene-bis-acrylamide (MBAm) or N,N’-cystamine-bis-acrylamide (CBAm). When heated in water above 33°C, it undergoes a reversible phase transition from a swollen hydrated state to a shrunken dehydrated state, losing about 90% of its mass. Since PNIPAm expels its liquid contents at a temperature near that of the human body, PNIPAm has been investigated by many researchers for possible applications in controlled drug delivery.[2][3] 呵呵,英文不是很好,是不是說明玻璃化轉變溫度為33℃。繌木S基百科上找到的,不知道對不對哦^_^ https://en.wikipedia.org/wiki/Poly(N-isopropylacrylamide) ![]() ![]() |
