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.
