Crosslinker energy landscape effects on dynamic mechanical properties of ideal polymer hydrogels by Khare, Eesha, de Alcântara, Amadeus C. S., Lee, Nic, Skaf, Munir S., Buehler, Markus J.

“…We report that, for an ideal network, the energy potential of the crosslinker interaction drives the viscosity of the network, where a stronger potential results in a higher viscosity. Additional topographical analyses reveal a mechanistic understanding of the structural rearrangement of the network as it deforms and indicate that as the number of defects increases in the network, the viscosity of the network increases. …”
