摘　　要：A novel supercapacitor based on ultralight and elastic three-dimensional (3D) porous melamine foam (MF)-derived macroporous carbon (3DPMFDMC)/reduced graphene oxide (rGO)/polyaniline (PANI) nanocomposites (denoted as 3DPMFDMC/rGO/PANI) were fabricated. By high temperature carboniza-tion, the commercial MF soaked in GO solution was prepared into ultralight and elastic 3DPMFDMC, the rGO were uniformly distributed into 3DPMFDMC to obtain 3DPMFDMC/rGO, and finally PANI was grown on the 3DPMFDMC/rGO by using in situ chemical oxidation polymerization method. The obtained 3DPMFDMC/rGO/PANI nanocomposites were characterized by SEM, FT-IR and Raman. The results showed the uniform distribution of rGO connected the broken fibers of 3DPMFDMC produced in the high temperature carbonization to improve the electrical conductivity and also enlarged the specific surface area of nanocomposites greatly. Lots of PANI were vertically arrayed on the surface of 3DPMFDMC/rGO. 3DPMFDMC/rGO/PANI exhibited a rapid electron/mass transport. Owing to its special structures and nanocomposites, the supercapacitor showed good electrical performance with a specific capacitance of 1870 F/g at the current density of 1 A/g. Moreover, the specific capacitance remained 95.4%after 1000 charging/discharging cycles at a current density of 5 A/g.A novel supercapacitor based on ultralight and elastic three-dimensional(3 D)porous melamine foam(MF)-derived macroporous carbon(3 DPMFDMC)/reduced graphene oxide(rGO)/polyaniline(PANI)nanocomposites(denoted as 3 DPMFDMC/rGO/PANI)were fabricated.By high temperature carboniza?tion,the commercial MF soaked in GO solution was prepared into ultralight and elastic 3 DPMFDMC,the rGO were uniformly distributed into 3 DPMFDMC to obtain 3 DPMFDMC/rGO,and finally PANI was grown on the 3 DPMFDMC/rGO by using in situ chemical oxidation polymerization method.The obtained3 DPMFDMC/rGO/PANI nanocomposites were characterized by SEM,FT-IR and Raman.The results showed the uniform distribution of rGO connected the bro ken fibers of 3 DPMFDMC produced in the high temperature carbonization to improve the electrical conductivity and also enlarged the specific surface area of nanocomposites greatly.Lots of PANI were vertically arrayed on the surface of 3 DPMFDMC/rGO.3 DPMFDMC/rGO/PANI exhibited a rapid electron/mass transport.Owing to its special structures and nanocomposites,the supercapacitor showed good electrical performance with a specific capacitance of1870 F/g at the current density of 1 A/g.Moreover,the specific capacitance remained 95.4%after 1000 charging/discharging cycles at a current density of 5 A/g.
