a Differential scanning calorimetry of the ELV-WP-FG/PUF composites showing the beta transition and Tg. b A plot of glass transition temperature as a function of graphene content, determined by the local minima of the derivative of the DSC heat flow. c, d Cross-sectional SEM analysis of ELV-WP-FG-PUF composite and neat PUF, respectively. The scale bars for both images are 5 μm.
