A new material, a nanocomposite based on polyaniline and yttrium oxide, has been developed at Kazan Federal University (KFU). This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
It is expected that the material will find application in the creation of sensors, optoelectronic devices, energy-efficient devices, and catalytic systems.
It consists of a conducting polymer, polyaniline, and yttrium oxide nanoparticles (Y₂O₃). Such nanocomposite materials attract attention with their unique properties due to the combination of the advantages of each of the components.
Polyaniline is characterized by chemical resistance and the ability to change conductive properties. Yttrium oxide has high thermal stability, resistance to aggressive environments, and good electrical properties. This allows it to effectively act as a charge acceptor in nanocomposites.
To study the properties of the material, scientists used a theoretical approach using the density functional method.
This method allows for a detailed analysis of how atoms interact with each other, what bonds are formed, and how the properties of the material change. The study included the calculation of geometry, electronic properties, energy characteristics, and the behavior of the material under the influence of light.
Research has proven that the material is stable due to the fact that the polymer and nanoparticle form a strong union through covalent bonds and electrostatic interaction. The nanocomposite is also capable of efficient charge transfer, as yttrium oxide clusters in its composition act as an "acceptor" of electrons, and polyaniline acts as a donor.
Earlier, www1.ru reported that in Tomsk nanocomposites were synthesized for the treatment of atherosclerosis.
