▎ 摘　　要

NOVELTY - The device has a handle connected with a fiber extraction head of a fixing tube. A pure graphite fiber is fixed on the fiber extraction head of the fixing tube via a high-temperature resistant rubber layer. USE - Solid-phase pure graphene micro-extraction device. ADVANTAGE - The device reduces pure graphene preparing cost, and has better mechanical property, adsorption property, thermal stability, prolonged service life and strong practicability, and reduces fragile defects.
