▎ 摘 要
NOVELTY - Preparation of a graphene/polypyrrole hybrid airgel comprises carrying out ultrasonic dispersion of graphene oxide nanotube and polypyrrole, liquid nitrogen quenching, freeze-drying, and high temperature hot processing at 200-800 degrees C. USE - Method for the preparation of a graphene/polypyrrole hybrid airgel (claimed) used for a super-capacitor electrode, and oil-water separator. ADVANTAGE - The method is simple and easy, and is inexpensive. The hybrid airgel has improved porosity, and has high conductivity.
