4 materials1 process step
Carboxylated graphene (1-10 mg/mL) is dispersed in water (solution A). 4-aminobenzenesulfonic acid is dissolved in water at 10-20 mg/mL (solution B). Solutions A and B are mixed in a 2:3 to 2:5 volume ratio with dibutyltin dilaurate catalyst (0.1-0.3 wt% of total volume), refluxed at 90-95°C for 8-10 hours, cooled to 85-90°C, then hydrazine hydrate (1-2 mL/g relative to carboxylated graphene) is added and reacted for 2-3 hours to yield sulfonated graphene.
5 materials1 process step
Sulfonated graphene is dissolved in water at 1-20 mg/mL. EDOT is added (weight ratio EDOT:sulfonated graphene = 1:1 to 100:1, preferably 3:1 to 10:1). A 5-30 wt% sodium persulfate (Na₂S₂O₈) solution is added such that sodium persulfate accounts for 10-60 wt% of sulfonated graphene. Reaction proceeds at room temperature for 4-8 hours, then the PEDOT/graphene composite paste is gathered and concentrated to obtain the functional composite material.
