- The effect of filler permittivity on the dielectric . . .
Thus, researchers resort to filler surface modification, filler morphologies, permittivity match between filler and matrix, as well as the multilayer film structure to obtain the good overall dielectric properties [14] Among these methods, many interests have been led to the permittivity match between filler and polymer
- The paradigm of the fillers dielectric permittivity and . . .
It was reported that the high aspect ratio fillers can improve the dielectric properties of the composites 35,71,72 Theoretically, the high aspect ratio fillers reach the percolation threshold more easily than the low aspect ratio fillers, which allows connectivity or continuous path in the system and improves the dielectric properties of the
- Effect of conductivity of filler on the percolation threshold . . .
Silver particles of two different grain sizes (3 5 and 5 μ m ) were individually mixed with PTFE and the corresponding variations in the dielectric properties were studied The composite containing Ag particles of size 3 5 μ m showed the percolation at 7 vol % , while for Ag particles of size 5 μ m , the percolation is at 10 vol
- A review concerning the main factors that interfere in the . . .
Besides the AR, the particle size, and the electrical conductivity of the antistatic agents, other factors may affect the electrical percolation threshold content of polymeric antistatic packaging such as the compatibility between the composite phases, the crystallinity degree of the polymeric matrix, the processing route and the localization
- Insights to low electrical percolation thresholds of carbon . . .
A rapid increase in electrical conductivity can be identified beyond the percolation threshold due to the formation of threshold conducting bridges [3] At higher filler concentrations above the percolation threshold, several conducting bridges are formed and an electrical conductivity higher then several orders of virgin polymer is manifested
- Two Percolation Behaviors in Binary Heterogeneous Composites . . .
increasing filler content and thus high permittivity could be achieved near the first percolation threshold, further increasing the filler content made the dielectric constant decrease but still kept positive, gradually the dielectric constant turned negative when the filler content was above second percolation threshold 2 Experimental
