Scientists have created new types of conductive materials

The team of Russian and American scientists created the new superplasticis in principle. It will be used in the manufacture of consumer electronics. For example, in cell phones and tablets. But, the most important area is medical technology, for example, the manufacture of pacemakers.

New superconducting metals include gold particles and spherical polyurethanes. It can stretch 4-5 times and still retain the ability to conduct electricity. Can call it the ideal material to produce gadgets. Today, this is the first in a family of new conductors that can be made from a variety of nanoparticles for different purposes. That's the opinion of expert Nicholay Kotov, who works on the project, is working at the University of Michigan in Ann Arbor, USA.

At first, physicists were afraid that superplastic metals could hardly be electrically conductive due to the resistance on the boundary between the spherical metal particles. However, experience shows that fear is unfounded. "When we stretch the metal, gold nanoparticles redistribute to maintain electrical conductivity," Kotov said . This explains the unique combination of superplasticity and conductivity in this material.

In order to maintain these characteristics, scientists took a long time to select the optimal ratio of spherical gold and polyurethane fillers. There are several new types of conductive materials.

The best specimen can stretch 4-5 times without losing the ability to conduct electricity. "That means that superconducting metals can be used not only for electronics and gadgets but also for the manufacture of pacemakers and prostheses," says Nikolay Kotov , The type of equipment requires flexibility.
