It is generally considered that plastics have extremely poor conductivity, so they are used to make insulating jackets for wires. But recently, researchers in Australia found that when a very thin metal film is covered on a plastic layer and mixed with ion beams on the surface of a polymer polymer, a low price, high strength, Plastic film with good toughness and conductivity.
The team that achieved this result was led by two experts from the University of Queensland, Australia, Professor Paul Meredith and Assistant Professor Ben Powell, and a professor from the University of New South Wales Expert Professor Adam Micolich (Adam Micolich). Their achievements have been published in the "ChemPhysChem" magazine. The experiment on which the institute is based was conducted by Andrew Stephenson, a former Queensland University doctoral student.
Ion beam technology is widely used in the microelectronics industry to test the conductive properties of semiconductors such as silicon wafers. However, attempts to apply this technology to plastic film materials only started in the 1980s and have not made much progress until now. Professor Meredith said: "The work done by this group is simply to use ion beam technology to change the properties of the plastic film material so that it has a metal-like function, can conduct electricity like the guide wire itself, or even become a superconductor , When the temperature is low to a certain extent, the resistance becomes zero. "
In order to show the potential application value of this material, the team adopted this material and made resistance thermometers with reference to industry standards. When compared with platinum resistance thermometers of the same type, the products made of the new materials showed similar or even superior performance.
"The interesting thing about this material is that we retain almost all the advantages of high molecular polymers-mechanical flexibility, high strength, low cost, but at the same time it has good conductivity, which is usually not The characteristics that plastics should have, "said Professor Mikhail. "This material opens up a new world of plastic conductors."
Andrew Stephenson believes that the most exciting aspect of this technology is that the conductivity of this film can be adjusted or set precisely, which will have a very broad application prospect. He said: "In fact, we can change the conductivity of this material by 10 orders of magnitude. Simply put, it is like we have 10 billion choices in our hands when making this material. Plastics that are completely non-conductive, or plastics that are as conductive as metals, and all the possibilities in between can be made. "
This new material can be easily manufactured using the equipment commonly used in the current microelectronics industry, and compared with traditional polymer semiconductor materials, this new material has much higher resistance to oxidation when exposed to oxygen.
The researchers said that combining these advantages, this thin film material obtained by ion beam treatment of high molecular polymers will have broad application prospects, and it is a perfect fusion of modern and future technologies.
