Effect of Inorganic Fillers on Electrical and Mechanical Properties of Ceramizable Silicone Rubber.

Figure 4 b demonstrates that the dielectric loss of the composite materials shows a decreasing trend with increasing muscovite content because wollastonite has a smaller density and is difficult to uniformly disperse in the silicone rubber matrix, which results in a more compact molecular structure, thereby constraining carrier mobility and diminishing the impact of leakage conductance on dielectric loss [ 37 , 38 ].
