    • A method of preparing a graphene material. The method includes: (1) preparing a liquid polyacrylonitrile (LPAN) solution, stirring the LPAN solution to yield a cyclized polyacrylonitrile solution; (2) stirring the cyclized LPAN solution at between 200 and 300°C to yield a thermally-oxidized polyacrylonitrile; (3) grinding and sieving the thermally-oxidized polyacrylonitrile, and drying a resulting product at room temperature, to yield a thermally-oxidized precursor; (4) calcining the thermally-oxidized precursor in the presence of an inert gas flow of between 10 and 500 mL/min for between 1 and 24 hrs at the temperature of between 400 and 1000°C, to yield a carbonized precursor; and (5) calcining the carbonized precursor in the presence of an inert gas flow of between 10 and 500 mL/min for between 1 and 10 hrs at the temperature of between 1000 and 3000°C, to yield a graphene material.
    • 一种制备石墨烯材料的方法。 该方法包括:(1)制备液态聚丙烯腈(LPAN)溶液,搅拌LPAN溶液,得到环化聚丙烯腈溶液; (2)在200-300℃之间搅拌环化的LPAN溶液,得到热氧化聚丙烯腈; (3)研磨和筛分热氧化聚丙烯腈,并在室温下干燥所得产物,得到热氧化前体; (4)在惰性气体流量为10-500mL / min的条件下,在400-1000℃的温度下煅烧热氧化的前体1至24小时,得到碳化前体; 和(5)在1000-3000℃的温度下,在10-500mL / min的惰性气体流动存在下煅烧碳化前体1至10小时,得到石墨烯材料。
