Scientists at the INM – Leibniz Institute for New Materials are exploring new routes to such coatings in "NanoSPEKT", a project funded by the Federal Ministry of Education and Research (BMBF).

They are aiming at flexible and transparent coatings that conduct electricity particularly well. The researchers combine inorganic nanoparticles with polymers and rationally arrange the particles inside the composite. The research will lead to particle-containing inks and coating methods that yield thin films with improved properties at lower cost.
"Today, the structure of composite layers is random. It does not help to develop highly conductive particles for composites if they do not touch each other: The electrons have to tunnel through the gaps, and electric conductivity is lost," says Tobias Kraus, head of the Structure Formation Group at INM. He and his colleagues strive to improve control of the distribution of the particles inside the layers.
It is already possible to coat large areas with conductive films, for example using so-called “roll-to-roll” production methods. The scientists at INM will use compatible methods to enable cost-efficient large-scale production . They study how the particles change in the composite during processing. "If we manage to pack the conductive nanoparticles more closely, the electrical conductivity of the film increases," says the group leader. This may be achieved by gently sintering the particles inside the polymer.Background
The funding initiative "NanoMatFutur" is part of the framework program "Materials Innovations for Industry and Society" (WING). WING combines traditional materials research withresearch on chemical technologies and materials-specific nanotechnology. It is part of the High-tech Strategy of the Federal Government.
INM – Leibniz Institute for New Materials, situated in Saarbruecken, is an internationally leading centre for materials research. It is an institute of the Leibniz Association and has about 190 employees.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
