Cavitation rheology was used to assess post-gelation elastic moduli of gels formed via sonication (Figure ). NIC has previously been shown to be effective at extracting elastic modulus information from soft materials . Sonicated samples were measured to have an elastic modulus near 1 kPa for samples starting at 100 DP, and 20 kPa for samples between 150 and 200 DP as measured by NIC. After a week of resting in a sealed tube to allow for residual epoxides to be consumed by thiols, the modulus of each sample increased to an average of 20 kPa for samples starting at 100 DP and 60 kPa for samples starting at 150 to 200 DP. The modulus derived from NIC shows polymers shielded with PEGMA950 cure into relatively weak materials.
