Table 2.
Water uptake after incubation at 37ºC in quenched and annealed films. For bulk water measurements the films were immersed in radioactive water (* p-value < 0.0001). Each value is the mean value of n samples from the same film ± SD. For confocal Raman image data, the value is the mean D2O content relative to C=C stretching band intensity (± SD).
