摘要：

Ring-opening polymerization (ROP) can synthesize polybenzoxazine (PBZ) precursors from their respective benzoxazine monomers, resulting in thermosetting phenolic resins. In this study, we synthesized DADCA-DADPM BZ using 4-(tert-butyl)-2,6-bis((E)-4-hydroxybenzalidene)cyclohexan-1-one (DADCA) and 4,4 '-diamino-diphenylmethane (DADPM) with paraformaldehyde. The resulting DADCA-DADPM BZ and poly(DADCA-DADPM BZ) _X materials were obtained after thermal curing polymerization at temperatures ranging from 110 to 250 degrees C were employed as electroactive materials in electrode preparation for supercapacitors (SCs). Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) revealed a thermal curing temperature of 230 degrees C, a char yield of 35 wt%, and a decomposition temperature (Td10) of 288 degrees C. The electroactive material DADCADADPM BZ and poly(DADCA-DADPM BZ)_X materials were evaluated for their suitability in SCs, showing a specific capacitance ranging from 84.6 to 166.6 F g- 1, depending on the thermal curing temperature (110-250 degrees C). Notably, the poly(DADCA-DADPM BZ)_250 retained 60% of its capacitance efficiency after 5000 cycles at current density of 10 A g- 1, highlighting its potential for recyclability.
