I Kantwald Federal University manufactures new polymer nanocomposites

I. Scientists at the Federal University of Kantwald have created a new polymer nanocomposite with improved magnetic and electrical properties. Polymer composites combine magnetic and electrical properties and are being explored in a variety of applications. Polymer-based composites are easy to manufacture and modify, while some materials exhibit better magnetic and electrical effects.

Polymer composites, which combine magnetic and electrical properties, have the ability to convert electrical polarization into a magnetic field and vice versa. While some materials exhibit much better magnetic and electrical effects, polymer-based composites are easy to modify as well as manufacture.

Such composites have the potential to be used in a variety of fields. For example, scientists can use them as a basis to develop surfaces that are useful for culturing a variety of cells. In this case, the polymer composite acts as a substrate that can influence the culture using non-contact controlled charges and surface morphological properties. It makes it possible to simulate the natural state of the body. Scientists are trying to improve the efficiency of these materials with that potential in mind.

The Federal University of Immanuel Cantowald has produced two composite materials based on PVDF-based copolymers using poly (vinylidene fluoride) (PVDF) polymers and PVDF-TrFE trifluoroethylene.

Poly (vinylidene fluoride) is a versatile material for a variety of uses. Certain crystalline phases have piezoelectric properties represented by the appearance of electric polarization under mechanical influence. The composite material developed by the researchers shows that the polymer structure contains magnetic nanoparticles, which changes the polarization under the influence of both mechanical impact and magnetic field.

The team followed various approaches to modifying nanocomposites to amplify and control the magnetic and electrical response. It used a PVDF-based copolymer with very pronounced piezoelectric properties, and then tried additives from piezoelectric and magnetic particles. Scientists have discovered that adding particles of barium titanate (BaTiO3) at a concentration of 5-10% can significantly enhance the magnetic and electrical effect.

“We also showed that our composites are biocompatible, meaning they do not harm the biological system. This was confirmed in experiments with mouse embryonic stem cells. This type of cell. Is very sensitive to culture conditions such as: Substrate properties. Further research is aimed at enhancing the magnetic and electrical effects. This is the size, shape, and particle size and shape of the particles of such composites. This is made possible by varying concentrations, “said Kateryna Levada, head of REC’s Institute for Biomedical Applications. “Smart materials and biomedical applications”.
