Table 1.

The water uptake of SG-80A and SP-60D-20 polyurethanes. Polymer films were weighed prior to immersing in PBS for 48 h at 37°C. The wet films were wiped dry and weighed again. The water uptake of the polymer films are reported in weight percent as follows: water uptake (wt%) = (W_wet – W_dry)/W_dry × 100, where W_wet and W_dry are the weights of the wet and dry films, respectively.

Polymer	Water Uptake (wt%)
SG80A	6.2 ± 0.7
SP-60D-20	22.5 ± 1.1
