Poly(n-isopropylacrylamide) (PNiPAAm), which is one of the thermosensitive hydrogels, has been used for many fields in sensing, drug delivery, tissue engineering, and so one. However, it has limited application to the body, because of its toxicity and slow degradation time. To overcome this problem, PNiPAAm has copolymerized with poly(ethylene glycol) (PEG) having highly biocompatibility and biodegradability. In this study, we characterized the thermal behavior of PNiPAAm-co-PEG hydrogel using infrared spectroscopy and two-dimensional correlation spectroscopy (2D-COS). The details of this study will be discussed in this presentation. |
