▎ 摘  要

NOVELTY - Preparation of composite phosphorus-doped reduced graphene oxide and polypyrrole polyurethane sponge comprises (i) dissolving 0.1-0.6 g methyl orange in 40-300 ml deionized water, stirring, adding pyrrole monomer, continuously stirring to obtain solution A, (ii) dispersing the prepared phosphorized reduction oxidation graphene in deionized water, dispersing uniformly, adding oxidant, dissolving, obtaining solution B, (iii) pre-cooling the solution A and the solution B to 0-4degrees Celsius, (iv) washing the sponge in the dispersion generated by the reaction, taking out and naturally drying, and repeating for 1-4 times. USE - Preparation of composite phosphorus-doped reduced graphene oxide and polypyrrole polyurethane sponge used for flexible super capacitor used in wearable electronic device. ADVANTAGE - The raw material used is low in price, and the preparation process is simple. The phosphorus-doped reduction oxidation graphene is good in the dispersion performance of aqueous solution, so that the system is more stable, can obtain uniform dispersion system. The insulating flexible substrate is effectively combined with the conductive material, on the basis of keeping the original compressible performance, which can be applied to the field of flexible super capacitor. With the change of the pressure, the resistance value change, the current is obviously increased under a certain voltage, it has a certain sensing performance, also can be used for pressure sensitive material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite phosphorus-doped reduced graphene oxide and polypyrrole polyurethane sponge.
