Electrospun PEGDM fibrous hydrogel characterization. (A) Mid-range IR identifies methacrylate conversion with UV exposure. (B) Fibrous architecture was investigated using confocal laser microscopy and scanning electron microscopy in both wet and dry states. (C) Shear stress vs. shear strain relationships for several PEGDM substrates prepared under different UV exposures. (D) Translation of shear-strain relationships into elastic modulus using a Poisson ratio ν ~ 0 [16].
