Fig. 5: Controlling porosity and pore textures via sulfonation time.
From: Accurate additive manufacturing of lightweight and elastic carbons using plastic precursors
a In-plane dimensional shrinkage and porosity of PP-CF derived carbon as a function of sulfonation time reported for a samples size of 3, error bars represent one standard deviation. b Framework porosity and BET surface area of carbonized samples as a function of increasing sulfonation time. Framework porosity is represented by an average of 3 measurements with error bars representing the standard deviation. BET surface areas are reported for a single sample. c Representative SEM image of 8 h sulfonated PP-CF after carbonization showing characteristic void spaces left by the removal of insufficiently crosslinked domains.
