Figure Legend:
Typical stress-stretch ratio curves during uniaxial tension testing of a 10% and 20% PVA cryogel membrane (both at 0.1 mm/s). The ultimate stretch ratios fall within the lower half of typical BMS expansion range .

Figure Legend:
Puncture pressure versus probe displacement for two typical PVA cryogels. Puncture pressure was calculated by dividing the load by the cross-sectional area of the drilled hole. Probe displacement is given as a fraction of the test mandrel radius. A fractional displacement of 1.0 is set as the safety requirement.

Figure Legend:
Push-through displacement versus membrane thickness for all puncture tests. Push-through displacement does not depend on membrane thickness within the range tested. The dashed line represents the push-through displacement safety requirement.
