Inorganic ferroelectric thin films and their composites for flexible electronic and energy device applications: current progress and perspectives

“…102,103 Secondly, it is necessary to maintain the mechanical stability between the IFE and the polymer matrix of the IFE-polymer nanocomposite. 104 The higher thickness of the IFE films (greater than 100 nm) causes mechanical instability between the IFE film and the polymer matrix, which creates delamination or a crack in the films. 105 This can be improved only by playing with the interfacial energy between the IFE and the polymer.…”

“…105 One possible method has been to functionalize the IFE surface with a low interfacial energy polymer matrix. 104,106,107 This in turn eliminates the defects associated with agglomeration and elevates the dispersibility. 104 Thus, the formation of nanoceramic-polymer composites has become a popular method for transforming an IFE bulk dielectric ceramic into the printable inks required for high productivity and industrial applications.…”

“…88,[109][110][111][112][113][114][115][116][117] Hybrid structures consisting of ion gels, electrolytes, and high-k metal-oxideembedded polymer dielectrics showed improved dielectric constants and low voltage operation. [118][119][120][121] Recently, dielectric inks containing 2D h-BN have been developed to achieve excellent printability and high-k dielectrics. [122][123][124][125] Zhu et al reported a one-pot coating of a flexible pinhole-free polyurethane (PU)/ h-BN composite (Fig.…”
