智慧化即時監控高品質石墨烯量產製程

Intelligent manufacturing of industry 4.0 is the one of the most important policies to upgrade and transform industries in Taiwan. Owing to the OEM business model, the most of the enterprises in Taiwan suffer from low profit. Hence, introducing intelligent manufacturing can be an opportunity to increase the profit via innovation. In another aspect, developing high value added products is another approach to enhance the industrial output value. For the reasons above, we conceive a project to combine the industry 4.0 with high value added product that is the mass production of graphene with real time intelligent monitoring. Here, Raman spectroscopy is used as the sensor in the monitoring system and is analogy to the sensor in the Cyber-Physical system of industry 4.0. Although the graphene has been proved its excellent abilities in many research fields, it is still rarely used in industrial products. The main obstacle hindering the graphene being applied in industry is the low quality of the commercial graphene. However, if we can develop a high quality graphene, many applications can be benefited from its spectacular properties, such as Li-ion battery and composite materials. This research is going to use the Hummers method to fabricate the graphene oxide and subsequently the graphene oxide will be reduce to graphene by using microwave heating. This process features with low cost of the facilities and highly accessible to the following uses. The reaction process will be monitored by the Raman spectroscopy and the measured data will be analyzed and stored in the cloud. Ultimately, we expect the synthesized high quality graphene can fill the need of the graphene in the market. Furthermore, the developed real-time monitoring system can be used in a wide range of industries, such as, chemical, biomedical and food industries.
