“…Whereas, the experimental value is close to the calculated value using Maxwell-Garnet model when f NBCTO ≤ 20 vol%, but there have lower predicted values with increasing in NBCTO content. Maxwell-Garnet model is applicable to those filler particles that are nearly spherical, uniformly distributed and non-interacting [18], whereas the NBCTO particles used in this work are non-spherical and would contact each other with the increase of NBCTO filler content, so there is a deviation between experimental and predicted values.…”

“…Up to now, many dielectric ceramics such as BaTiO 3 [3][4][5][6][7][8][9][10], BaSrTiO 3 [11], Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 [12] and CaCu 3 Ti 4 O 12 (CCTO) [13][14][15][16][17][18] have been used as fillers in polymer matrix due to the high dielectric permittivity. Na 0.5 Bi 0.5 Cu 3 Ti 4 O 12 (NBCTO), similar to CCTO, is a leadfree material with pseudo-perovskite structure and no piezoelectric effect, which also exhibits a colossal dielectric permittivity of about 10 4 and dielectric loss as low as 0.1 at room temperature [19,20].…”

“…Different mixtures of graphene and graphene oxide as reinforcements for PU have been studied by many researchers in previous years and have shown remarkable improvements in various properties . Other popular choices over the years for reinforcing particles for PU have been metallic powders, ceramics particles, nanoclay, natural clays, modified sand etc . Among these different kinds of reinforcements, TEMs of different forms of natural clays embedded in the PU matrix from a previous study are shown in Figure .…”

“…[93] TPUs have the advantages of high efficiency, excellent reliability and fast response during electric actuation. [94] However, its endogenous heat is huge, and it produces a large amount of heat during electric actuation, which limits its application in the field of electronic materials. [95]…”
