Characterization of the LCST behaviour of aqueous poly(N-isopropylacrylamide) solutions by thermal and cloud point techniques
TLDR
In this article, a systematic investigation of phase separation behavior of aqueous low molecular weight PNIPA solutions was carried out in order to quantitatively investigate the effect of measurement conditions on the reported phase separation temperatures in relation to three techniques, namely, differential scanning calorimetry, optical cloud point and u.v. turbidimetry.About:
