浙江大学的研究人员在石墨烯纤维的规模化制备及高性能化研究等方面取得新突破。研究人员首次提出了“全尺度协同缺陷工程”策略,实现了高性能石墨烯纤维的规模化制备,制得的石墨烯纤维直径最细可达1.6μm,力学强度最高可达2.2GPa,导电率达8×10~5S/m,为目前石墨烯纤维性能的最高水平。基于此,研究人员进一步采用“化学掺杂”方法,将氯化铁、溴、钾等物质引入到石墨烯 Researchers at Zhejiang University made new breakthroughs in the scale preparation of graphene fibers and high performance research. For the first time, researchers proposed a “full-scale collaborative defect engineering” strategy to achieve large-scale preparation of high-performance graphene fibers. The graphene fibers obtained can be as fine as 1.6 μm in diameter and have a maximum mechanical strength of 2.2 GPa. Electrical conductivity of 8 × 10 ~ 5S / m, the highest level of the current performance of graphene fibers. Based on this, the researchers further use “chemical doping ” method, the ferric chloride, bromine, potassium and other substances into the graphene
