Preparation and Related Applications of Graphene, Dispersions and Composites（主题会场：石墨烯在导电油墨领域的应用）
High-efficient, low-cost preparation of graphene with desired structures and properties is critical for large-scale applications. However, it remains difficult in many cases especially for those applications that have strict requirements such as large lateral sizes, high electrical conductivity, good dispersion capability and excellent compatibility with various matrices. We have developed preparation methods of graphene sheets with different structures and properties, which afford convenient approaches to incorporate graphene sheets into different matrices, to form dispersions or to construct high transparent electrically conductive films. These application examples exhibit intriguing potential in different fields, such as functionality composites, optoelectric films etc.
Large-scale Preparation of Graphene with Different Structures（主题会场：石墨烯/氧化石墨烯规模化制备技术）
Until now, it remains a hurdle to produce graphene with desired structures in a scalable manner. The industrial efficiency, storage, transportation and simplicity to apply in downstream products are also critical issues necessary to be addressed. We have developed a series of techniques to produce a variety of graphene sheets that are expected to be viable for different application requirements, including high-contents of graphene aqueous dispersions (up to 25 wt% in water), ultra-large graphene oxide sheets (average lateral size up to 120 mm or more) and almost defect-free high quality graphene with a yield of 70% under atmospheric condition. These techniques provide effective approaches for efficient industrial production and good application potential.
