Flexible dielectric polymer nanocomposites with improved thermal energy management for energy-power applications

Most polymer materials are thermal and electrical insulators, which have wide potential in advanced energy-power applications including energy conversion. However, polymers get softened when contact with heat, causes their molecular chains to flow as the temperature increases. Although dielectrics exhibit high power density, they face challenges of low density is due dielectric permittivity associated them. Therefore, this study tried address poor management poly (vinylidene fluoride) (PVDF) while maintaining its flexible property using content hybrid carbon nanotubes (CNTs–0.05wt%, 0.1wt%) boron nitride (BN–5wt%, 10wt%) nano-reinforcements. The nanocomposites were developed through solvent mixing hot compression processes. constant increased from 9.1 for pure PVDF 42.8 a loss about 0.1 at 100 Hz PVDF-0.1wt%CNTs-10wt%BN. stability was enhanced by 55°C compared PVDF. also showed improved melting crystallization temperatures. PVDF-CNTs-BN significant enhancements management, stability, properties. significantly properties credited synergetic effects between CNTs BN matrix promoting homogeneous dispersion, barrier, interfacial polarization/bonding, insulative conductive nanomaterials can find sector owing performances.
