There has been a longstanding debate about whether graphite or copper is a better EDM electrode material.One of main reasons people have historically used copper within Electrical Discharge Machining (EDM) is because it is cleaner in their working environment, but is that where the advantages of the

As the first two-dimensional material to be discovered, graphene has rapidly attracted worldwide attention and research interest since its inception in 2004.Although 15 years have passed, the research on graphene and related two-dimensional materials is still hot, and emerging research fields are constantly being developed.Under the background of the current new round of industrial upgrading and technological revolution, the new material industry will surely become the cornerstone and leader of the future development of high-tech industries, and will have a profound impact on the development of the global economy, technology, environment and other fields.China is a country with large graphite resources and one of the most active countries in graphene research and application development.As a new carbon-based material, graphene has good optical, electrical, thermal and mechanical properties. It has broad application prospects in the fields of electronic information, new materials, new energy, and biomedicine. It is becoming a global new technology and new industrial revolution. Focus.At present, more than 80 countries around the world have invested in the research and development of graphene materials.

C/C composite materials are the main breaking point of new materials in the future. I think that the current research and development focus is not on the repeated research on their preparation, but on their application research in the preparation process, especially on traditional industries, new energy Industrial modification research.

Carbon nanomaterials can replace silicon in computer chips and change many other industries, but why are they lingering on the edge of commercialization?

Applying graphene, a two-dimensional carbon nanomaterial with special structure and excellent performance, to civil engineering can comprehensively improve the performance of engineering materials and expand the application field of graphene.By reviewing the research status and development trends of graphene-asphalt composites in the field of civil engineering at home and abroad in recent years, it is found that the incorporation of graphene into asphalt improves its road performance, but there is a lack of relevant research, such as fine characterization of graphene-asphalt structure, The microscopic action mechanism of the unique behavior of graphene-asphalt, the change law of key behavioral characteristics of graphene-asphalt and asphalt mixture, and the graphene-asphalt composite material system.Graphene was incorporated into pitch 70, and the graphene pitch mixture was initially explored using both macroscopic and microscopic research methods.The research results show that graphene has an affinity for asphalt and can be intercalated or exfoliated by hot asphalt to form a supramolecular structure with graphene sheets as the basal plane; the incorporation of graphene significantly improves the behavior of asphalt, especially low-temperature performance.Graphene (G
