Composite of aromatic polythiourea/BaTiO3 nanowires with high energy density and high discharge efficiency for energy storage applications

Ceramic/polymer nanocomposites have shown great potential in high energy storage density capacitors for pulsed power applications. However, due to the difference surface between inorganic fillers and polymers, discharge efficiency of are limited. In this article, BaTiO3 (BT) nanowires (NWs) modified with dopamine (Dopa) was introduced into aromatic polythiourea (ArPTU) polymer matrix as composite high-performance dielectrics. This is a new path about introduction dielectric constant ceramic dipole moment linear polymers (HDMLP), which produces efficiency. The ArPTU/BT NWs shows an 7.5 J cm−3 more than 90% obtained under electric field 250 MV m−1. It also has been found that modification BT Dopa reduces loss effectively good synergistic effective ArPTU NWs, stability achieved. work provides solution achieving dielectrics practical capacitor
