Poly(vinyl alcohol): Physical Approaches to Designing Biomaterials for Biomedical Applications
Figure 2
A comparison of the infrared absorbance peaks of 10% PVA (w/v) air-dried only (AD), air-dried and single freeze-thawed (AD+1FT), and single freeze-thawed only (1FT) hydrogel films. All three spectra are normalized to allow comparison.
