This Small Business Technology Transfer (STTR) Phase II project aims to develop a method for rapid, direct and large-scale production of pristine nano-graphene platelets (NGPs). A combined molecular dynamic, macroscopic modeling and experimental approach will be used to (1) further improve the understanding of the underlying principles behind effective peeling of single-layer graphene sheets from graphite particles in selected liquid mediums, and (2) to clearly determine the most critical processing conditions that govern the graphene production rate in a continuous processing reactor. The broader/commercial impacts of this project will be the potential to offer a cost-effective method to produce pristine nano-graphene in large quantities. NGPs are of exceptional scientific and technological significance. The ability to produce large-volume pristine nano-graphene will have a profound impact on the evolution of nano-graphene science and technology. Highly conductive graphene may find practical applications in transparent and conductive coating, supercapacitor, battery electrode, fuel cell bipolar plates, and conductive nanocomposite.

这个小企业技术转让（STTR）第二阶段项目旨在开发一种快速，直接和大规模生产原始纳米石墨烯片晶（NGP）的方法。 结合分子动力学，宏观建模和实验方法将用于（1）进一步提高对单层石墨烯片在选定液体介质中从石墨颗粒有效剥离背后的基本原理的理解，以及（2）明确确定控制连续加工反应器中石墨烯生产速率的最关键加工条件。该项目的更广泛/商业影响将是提供大量生产原始纳米石墨烯的成本效益方法的潜力。 NGP具有特殊的科学和技术意义。生产大体积原始纳米石墨烯的能力将对纳米石墨烯科学和技术的发展产生深远的影响。高导电性石墨烯可在透明导电涂层、超级电容器、电池电极、燃料电池双极板和导电纳米复合材料中找到实际应用。
