Limit the first breakthrough materials can prepare the super capacitor was born
Fudan university professor of polymer science and advanced materials laboratory Peng Huisheng team through the design of a new preparation method of rotating shift, the first successful preparation of tensile linear super capacitor, thus effectively combines the elasticity of polymer material and excellent electrical and mechanical properties of carbon nanotubes. Flexible portable devices is one of the main development direction in today's electronic devices, flexibility is one of the essential characteristics. The elastic electronic devices, such as electrochemical supercapacitors, lithium-ion batteries, organic solar cells is in a traditional planar substrate. Portable applications must have the quality light, small volume, high efficiency, etc, also has certain elasticity, research work is extremely challenging. In recent years, there are a lot of preparation of linear micro devices. Compared with planar structure, linear structure has the advantages of light weight and can be woven. Usually, the coaxial structure and winding structure of super capacitor under the condition of bending still has excellent performance, but they do not have flexibility, and flexibility is of vital importance in many applications. Practical application of textile electronic devices, for example, if you don't have elasticity is easy to break and damage. So far, there is no research on stretchable high-performance linear super capacitor, this is mainly limited to the electrode materials. Fudan university team designed a rotating translation method, which can effectively combine the flexibility of polymer and carbon nano tube, excellent electrical and mechanical properties of the first successful can stretch of line super capacitor is prepared. The capacitor can be bending, folding and stretching, and in the case of tensile 7 5% can 1 00% to keep various properties of the capacitor. This linear capacitor can be further woven into the fabric of all shapes, and can be integrated in all kinds of miniature electronic devices, to meet the future demand for micro energy. It is understood that the research work published online in the journal of applied chemistry, Angew. Chem. Int。 艾德。 ) Magazine.
