“…Two-dimensional correlation spectroscopy (2D-COS) 20 is a very powerful analytical method to deeply understand the complicated IR spectra of the polymers. [21][22][23][24][25][26][27] In our previous study, we have successfully elucidated the phase transition mechanisms of PNiPAAm homopolymer hydrogel 26 and poly(N-isopropylacrylamide-co-acrylic acid) [P(NiPAAm-co-AAc)] copolymer hydrogel 22 using the 2D-COS.…”

In this study, one of the thermoresponsive polymers, block copolymer consisting of poly(ethylene glycol) and poly(N-isopropylacylamide), was investigated using Fourier-transform infrared (FTIR) spectroscopy, principal component analysis (PCA), and two-dimensional correlation spectroscopy (2D-COS). The apparent trend of the spectral changes in the temperature-dependent FTIR spectra of poly(ethylene glycol)-block-poly(N-isopropylacylamide) (PEG-b-PNiPAAm) hydrogel during the heating process looks similar to that during the cooling process. The results of the PCA and 2D-COS, however, indicate clearly an irreversible phase transition mechanism of PEG-b-PNiPAAm hydrogel during the heating and cooling processes. It has been also shown that PEG affects the phase transition mechanism of PEG-b-PNiPAAm hydrogel, especially during the heating process. Consequently, we can successfully determine the phase transition temperature and the mechanism of PEG-b-PNiPAAm hydrogel during the heating and cooling processes using PCA and 2D-COS, respectively.

This article outlines the recent progress in 2D correlation spectroscopy (2D‐COS), especially new and noteworthy developments and its applications. 2D‐COS is a powerful technique applicable to the in‐depth analysis of various spectral data, especially those obtained in various practical spectroscopic experiments. 2D‐COS has undergone rapid developments. This article highlights new types of 2D correlation analysis, such as combination of chemometrics and 2D‐COS, moving‐window 2D analysis, projection 2D analysis, hetero‐correlation analysis, 2D codistribution spectroscopy (2D‐CDS), smooth factor analysis (SFA), two‐trace two‐dimensional (2T2D) correlation spectroscopy, as well as experimental practices, such as various perturbation methods, fields of applications, and analytical probes employed.
