| 目的 得到关于氧化石墨烯制备的最佳工艺条件。方法 以绿色四氧化二氮推进剂和石墨为原料，开展基于化学电位法和超声法制备氧化石墨烯的实验研究，结合对氧化石墨烯产物进行扫描电子显微镜(SEM)和X-射线衍射仪(XRD)表征。结果 对于氧化石墨的制备，最佳初始ORP区间为1700~1800 mV。石墨与N2O4配料比为1︰10、低温预处理工艺H2O2用量为18 mL、KMnO4用量为1.5 g、氧化温度为30 ℃、氧化时间为120 min是最佳工艺条件。对于氧化石墨烯的制备，分散溶剂pH为11，分散功率为150 W，分散时间为40 min是超声分散的最佳工艺条件。结论 采用该工艺条件制备氧化石墨烯，既有利于解决大批量报废硝基氧化剂的转化处理难题，也制备得到了氧化石墨烯这种高附加值的民用工业产品。 |

| Objective To obtain the optimum experimental conditions for preparation of graphene oxide. Methods Mixed Oxide Nitrogen-3 (MON-3) and graphite were used as raw materials for the preparation of graphene oxide based on chemical oxidation potential and ultrasonic method. The products of graphene oxide were characterized by SEM and XRD. Results For preparation of graphite oxide, the optimal initial ORP range was 1700 - 1800 mV. The graphite and N2O4 ingredient ratio of 1:10 H2O2 dosage, low temperature pretreatment of 18 mL, KMnO4 consumption of 1.5 g, oxidation temperature of 30 ℃, and oxidation time of 120 min were the best process conditions. For preparation of graphene oxide, the dispersion solvent pH of 11, scattered power of 150 W, dispersing time of 40 min were the best process conditions of ultrasonic dispersion. Conclusion Preparation of graphene oxide with these process conditions is not only helpful to solve the conversion problem of large quantities of scrap nitro-oxidants, but also can prepare graphene oxide, which is a high value-added civil industrial product. |
