a Representative compressive stress-strain curves of PP-CF derived carbons, which were crosslinked at 150 °C for different times. b Photos showing compressive strain recovery behavior in carbons derived from partially crosslinked PP-CF. c Resulting specific mechanical properties of carbons including compressive strength, modulus, and energy sorption with varying crosslinking time. Reported values are averages based on four measurements, and error bars represent the standard deviation. d Cyclic compressive stress-strain curves of carbonized samples (crosslinked at 150 °C for 6 h) brought to 40% strain.
