Extended Data Fig. 3: Chemical resistance test of PCN films.
From: Recyclable and malleable thermosets enabled by activating dormant dynamic linkages
a, Chemical resistance test for PCN-A4 film. b, Chemical resistance test for PCN-A6 film. c, Chemical resistance test for PCN-A12 film. The PCN films were cut into the rectangular shape and submerged in different solutions (1 M HCl, 1 M NaOH, 30% H2O2 and 1 M NaBH4); the top, middle and bottom photos were taken before submerging, after 48-hour submerging, and after drying, respectively. No change in appearance was observed for all the PCN films.
