Abstract
This work reports the advances of utilizing molybdenum disulfide (MoS2) nanosheet superstructures to enhance dielectric property and electrical energy storage capability of flexible ferroelectric polymer composites. Hydrangea-like flowers or clusters comprising MoS2 nanosheets were synthesized by hydrothermal methods and used as filler of ferroelectric polymer composites. Both MoS2 superstructure based composites show percolation-like electrical behavior. The composites with high loading of MoS2 superstructures exhibit significantly enhanced dielectric constant, whereas those with low loading of MoS2 superstructures can withstand high electric field and exhibit significantly enhanced electric polarization, resulting in significant improvement of electrical energy storage capability. The MoS2 flowers show strong potential to enhance the dielectric constant and electrical energy storage capability of the composites.
