(a) shows the nonlinear compressive/elastic modulus through the stress-strain curves for different crosslink densities. Experimental results and the model are compared. (b) shows the equilibrium swelling ratio as a function of crosslinking density for stable PEG hydrogels formed from PEGDM macromers obtained both experimentally and determined by the model. Error bars indicate standard deviation (n = 3).
