Adding new composite shoes made of graphene

HC Plastics News: In the new products on the market, graphene materials have been added to add some functional capabilities to ordinary objects: footwear with better heat dissipation performance. Developed by the graphene flagship company of Italy's Istituto Italianodi Tecnologia and FADEL, the leading Tuscan shoe company in Italy, FADEL's newly developed technology for patents gives the footwear better temperature regulation and durability.

In the manufacture of this new shoe, when several layers of graphene sheets were added to the polyurethane (FADEL sole material), laboratory tests showed that the heat dissipated in the material was increased, the waterproof performance became stronger and the antibacterial property Performance is constantly improving. Combine these effects with a ventilating device developed for this particular type of shoe with a better user experience. The prototype of this shoe was shown at the International Footwear Fair in Milan.

Graphene has opened up a wide range of applications due to its excellent electrical conductivity, mechanical properties and heat dissipation properties due to its unique two-dimensional model structure, attracting more and more attention. This fascinating property makes graphene a promising material for a variety of practical applications. Different graphene nanocomposites can be easily prepared by functional modification of graphene. The graphene bulk properties are preserved to the greatest extent and other meaningful properties are introduced through functionalization. Further in-depth research will obtain a series of new graphene functional materials with better performance, and lay the foundation for further realizing the practical application of such materials scientifically and technically.

One of the main characteristics of graphene is its excellent heat dissipation performance, so we began to consider the combination of graphene produced by liquid phase stripping (a method that can produce a large amount of graphene at a lower price) into polyurethane - for polyurethane The sole of this material footwear. This creates a composite that is 50% better than a pure polyurethane material. Vittorio Pellegrini, director of the IIT Graphene Laboratory and chairman of the Graphene Flagship Executive Committee, said. “We used a small amount of graphene (about 1%) to improve the heat dissipation of the footwear, which is very important in terms of the cost of production is not much more than before.”

Once the researchers at the IIT Graphene Laboratory have optimized the way graphene is added to polystyrene, graphene production has been completed by IIT's startup and the member of the Graphene Flagship Association, BeDimensionalsrl, whose core operation is the addition of graphene and Based on the development of new composite materials for other materials related to manufacturing applications.

Graphene's flagship company is a powerful accelerator for knowledge, skills and technology transfer. Pellegrini said that if there is no shoe of the graphene flagship company, it will take many years for the shoe to be developed. We have benefited from sharing our research and our ability to get inspiration from other scientists through flagship companies.

Dr. Kari Hjelt, Innovation Director of Graphene's flagship company, said that we will continue to witness the potential for market volatility and innovation in graphene technology. Graphene can simultaneously enhance the special properties of multiple product attributes and, as is the case today, can create a commercial competitive advantage for many products.

Professor Andreac. Ferrari, chairman of the science and technology staff and management team of Graphene's flagship company, added that this is another example of the steady progress of graphene and related materials from the laboratory to the factory floor. As more and more companies become partners or joint members of flagship companies, flagship companies not only promote the development of science and technology for graphene and related materials, but also promote reform and innovation.

The function for SINOFUJI Overhead Line Cover is to shorten the safety distance, increase the creepage distance, prevent bird damage, prevent wind deflection, prevent air floating objects and various plants from being collided or contacted, it can be eliminated electromagnetic radiation (induction) Impact on people and animals who are nearby the overhead line.

Being equipped with special installation tools with the principle is similar to that of clothe zipper, it can be installed without shut down the power (the voltage is 10kV or below). The operator can install up to 80 meters of overhead line by standing on one fixed position, the installation speed can be reached as high as 20 meters/5 minutes if two people working together in a team.
