WebThe frequency sweep and slope of the storage modulus (G') of XCHC was significantly closer to curdlan with higher elasticity and less dependency upon angular frequency than xanthan alone. The reduction in XCHC dynamic moduli (G' and G″) compared to curdlan could be attributed to the formation of wavy layers instead of a fully cured three … WebFor the PIC hydrogels, each frequency sweep was performed at a strain amplitude of 1%, while it was set to 10% for the PEG hydrogels. These strain amplitudes are in the linear viscoelastic range of each respective hydrogel. The frequency was varied from 0.0001 to 10 s −1. Additional data sets are shown in Supplementary Figure 6.
