To fill this gap, we herein successfully fabricated a series of BaTiO3@TiO2@SiO2/PEI and BaTiO3@SiO2@TiO2/PEI nanocomposites, the energy storage density of which can reach 5
Based on the electrostatic interaction between PHT and PEI polymer chain, a physical cross-linked network is formed in the polymer blend, and the construction of electron-hole pairs in the interface region obviously improves the energy storage performance of the composite .
The results show that the composites exhibit considerably increased Young’s modulus, suppressed conductivity loss, and improved breakdown strength compared with pure PEI. Consequently, a stable energy storage performance is realized for ZIF-67/PEI composites.
Compared with pure PEI films and BT/PEI nanocomposites, PHT@BT/PEI nanocomposites possessed excellent energy storage performance. The maximum Ue of 7.62 J cm −3 and the efficiency of 89 % is achieved in the 0.3 wt% PHT@BT/PEI at 641 MV m −1 at room temperature.
More importantly, the 0.3 wt% PHT@BE/PEI composite delivered the maximum Ue value of 7.62 J cm −3 at 641 MV m −1, which was 1.94 times than that of pure PEI (3.93 J cm −3), revealing that a small number of modified nanoparticles can effectively improve the energy storage capacity of PEI by improving the polarization and breakdown strength.
The enhancement mechanism of energy storage performance is studied. The discharge energy density of PEI-based nanocomposites at 150 °C is 4.86 J cm −3. With fast development of modern industries and electrical systems, polymer dielectrics are urgently demanded to have high discharged energy density (Ud) in elevated temperature.
From the microscopic point of view, the lowest unoccupied molecular orbital level of PEI is close to the highest occupied molecular orbital level of PHT, and it is easy to establish the electron-hole pair by coulomb force, and further establish the carrier trap.
