Physical Structure and Thermodynamic Characterization. a Chemical structures of the precursors used to synthesize polymer networks employed in the study. b Photograph of a typical polymer network specimen. c Schematic illustrating the concept of in situ crosslinking on a metal electrode. d Thermograms obtained from Differential Scanning Calorimetry (DSC) for polymer network membranes for various fractions (Φ) of PEGDMA. The dotted lines mark the step-change in the heat-flow discussed in the text. e Glass Transition temperature as a function of PEGDMA fraction (Φ) in the membranes. The red line is the Gordon-Taylor fit to the experimental results
