AP22788736 – A synthesis and research foundation for polyampholytes as ionic polymers for energy storage systems
Objective of the project: The aim of the project is to develop the scientific foundations for the synthesis of highly charged polymer electrolytes based on polyampholytes for energy storage systems, followed by a study of their physico-chemical, mechanical, rheological and electrically conductive properties.
Relevance: Energy storage systems are becoming critical components for the sustainable development of the energy sector, especially with the increasing use of renewable energy sources and electric vehicles. Enhancing the efficiency and reliability of these systems requires new materials and technologies. Polymers, including polyampholytes, present a promising avenue for energy storage, though their properties and applications are not yet fully explored. The relevance of this project lies in the in-depth research of the synthesis and utilization of polyampholyte-based polymer electrolytes to improve energy storage systems.

Expected and achieved results: The viscoelastic properties of polyampholyte-based hydrogels were studied using rheological tests, revealing that the storage modulus (G′) exceeds the loss modulus (G″) for all samples. The incorporation of the DmaM monomer increased the elasticity and enhanced the structural stability of the hydrogels. Reducing the concentration of the MBAA crosslinker led to network loosening and increased polymer chain mobility. Conductivity measurements showed that the hydrogels exhibit ionic conductivity in the range of 10⁻⁵–10⁻³ S/cm, with higher DmaM content significantly improving conductivity. Additionally, optimization of the DMC solvent concentration enhanced ion transport and overall conductivity performance. These findings demonstrate the potential for precise tuning of hydrogel properties for biomedical applications.
