The research and development of chiral graphene has attracted attention and related research results are increasing.
According to the “Chiral Graphene Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” released by the Industrial Research Center, Graphene is a nanomaterial with excellent optical, electrical, and mechanical properties. It is considered a new material that may change the world. It has a wide range of downstream uses, so its technology and application research have attracted great attention. A chiral carbon atom is a carbon atom with four different functional groups. Its mirror image atom cannot overlap with the atom itself and has many unique properties. Among new carbon materials, chiral graphene has attracted attention in research and development due to its special optical, mechanical and other properties.
Chiral graphene can be prepared into chiral graphene fibers, which can rotate at high speed when stimulated by polar solvents. This feature can be used to prepare high-sensitivity kinetic energy, electrical energy output systems, and gravitational potential energy collection systems. New materials can also be prepared. In March 2019, a team from Zhejiang University used flexible graphene oxide films as raw materials and twisted them into graphene oxide fibers with a spiral texture, giving them a symmetrical chiral structure, high flexibility and a large amount of stress potential energy.
Chiral graphene can be prepared into chiral graphene nanofiltration membranes, which have excellent mechanical properties, ultrasonic resistance, permeation selectivity and service life, and have broad application prospects in industrial filtration, separation, concentration and other fields. In August 2020, a team from the Institute of Membrane Separation and Water Science and Technology of Zhejiang University of Technology introduced chiral polymer molecules into the layers of graphene oxide for the first time and self-assembled to prepare chiral oxide with ultra-stable performance and ultra-strong structure in liquid separation. Graphene nanofiltration composite membrane (rGO/PLDA).
Chiral graphene can be used to prepare chiral liquid crystal materials. It has unique optical rotation and circularly polarized light characteristics. Therefore, it has the ability to modulate light at different scales, and has the characteristics of reducing blue phase driving voltage, rich optical anisotropy, and good for It responds quickly to external stimuli such as light, electricity, magnetism, etc., and has great development prospects in the field of optics. In July 2020, researchers at Fudan University applied nanofluidic rectification technology to prepare chirality-inverted graphene oxide (GO) liquid crystal. The method is simple to operate and easy to produce on a large scale. The prepared liquid crystal fiber has a long-range ordered structure, Stable topology and controllable optical appearance.
Industry analysts said that chirality is an important symmetry feature in many disciplines. In the field of material development, chirality The ability of materials to exhibit unique properties has become an important research topic. Graphene has excellent optical, electrical, mechanical and other properties. It is regarded as a new material that can change the world. It has great application potential in many fields and is highly researched. The combination of chirality and graphene can develop new and unpredictable special materials. Therefore, the research results of chiral graphene will continue to increase in the future, but it has not yet been commercialized.
