SANS profile and FTIR-ATR spectral changes of a d-THF solution of PEG: (a) time-dependent radially averaged SANS I(Q) profiles in the log–log plot; (b) the polymer morphology model; and (c) time-dependent IR spectral changes in the CH2 stretch region, CD2 stretch region and a portion of the fingerprint region, respectively. The bands with red and sky-blue arrows are attributed to the A2 and E1 modes, respectively. |
