Graphene nanosheets are two-dimensional materials of single-atom layer thickness composed of sp2 hybridized carbon atoms that exhibit a range of unusual physical properties. In 2004, Novoselov et al. prepared a graphene nanosheet sample by tape stripping method, and characterized its microstructure and physical properties. Graphene is the toughest, conductive and thermally conductive material found to date. Graphene nanosheets have attracted great interest from researchers in the fields of physics, chemistry and materials because of their special two-dimensional structure. In order to make graphene reach the engineering application status as soon as possible, the EU launched the graphene flagship technology project in 2012, and the United States has also invested heavily, and some breakthroughs have been made in the application research field of graphene as a super-capacitor.
Graphene is an ideal composite nanofiller. Due to the high strength of graphene, how to use it to improve the strength of composite materials has become a research hotspot. There have been reports on graphene nanosheet reinforced polymer and ceramic materials. The young scientists at the Aviation Materials Institute are brave in their own innovation. They have successfully produced graphene-reinforced aluminum-based nanocomposites (named “Aluminum-Based Alloysâ€) by ball milling and powder metallurgy. It is the first time in the world that graphene nanosheets have been found. The material is plastically improved while significantly increasing its strength.
They used OM, SEM and TEM to characterize the microstructure of the aluminum-based alloy and test its tensile properties. The results show that the graphene nanosheets are evenly distributed in the aluminum alloy matrix, forming a good bonding interface with the matrix, and the graphene nanosheets do not chemically react with the aluminum alloy matrix, and retain the original nanosheet structure; aluminum olefin alloy When the content of graphene nanosheets is 0.3% (mass fraction, the same below), the yield strength and tensile strength of aluminum olefin alloys are 322 MPa and 455 MPa, respectively, which are 58% and 25 higher than those without graphene nanosheets. %, and the elongation of the alloy is not lowered.
The successful development of the olefin alloy has announced that a new generation of new materials with special excellent performance has been born, filling the gap in the field of materials science in the world, and then pushing this discipline to a new field. At present, young researchers at the Institute of Aeronautics and Astronautics are exploring further unknown areas of graphene research, and in-depth research on the enhanced toughening behavior of graphene nanosheets is underway.
The boring situation of the international graphene research has finally been broken. A group of young researchers from AVIC Aviation Materials pioneered the “alkenyloy†material in the field of international graphene research. This landmark major independent innovation not only invented a new class of high-end alloy materials with excellent properties, but also China has become a leader in the frontier and applied research of graphene as a material science. The new term “alkeny alloy†is a new term in the history of world material technology development.
