* Electrical properties: Dk, Df, volume resistivity (p), and surface resistivity
Offered in black only, their surface resistivity
is less than 105 Ohms per square.
It has been perceived since long that the integration of resistivity parameters extracted from surface resistivity
measurement has a strong correlation between aquifer properties, as electrical properties are affected by porosity, permeability, heterogeneity, orientation of grains, compaction and consolidation (Mazac et al., 1985; Huntley, 1986; Mazac et al., 1988; Borner et al., 1996; Christensen and Sorensen, 1998; de Lima et al., 2005; Niwas et al., 2006; Rubin and Hubbard, 2006).
Moreover, also in our previous article on PLA based nanocomposites it was reported how the combination of vapor grown carbon fibers (VGCF) and exfoliated graphite nanoplatelets (xGnP) fillers promoted a further decrease of surface resistivity
with respect to the corresponding binary systems .
The measurements are taken by several available methods based on uniaxial or bulk resistivity, surface resistivity
, electrical impedance spectroscopy, and noncontact resistivity measurements based on the transformer principle [1-5].
The modification with heavy atoms might lead to more sensitive graphene sensors as due to increased surface resistivity
large current spikes might be easier to detect.
The key property of the Luranyl HT grade is the surface resistivity
of the material, aiding the powder coating process and allowing for more positive results than the incumbent grade.
Designed for use with the vendor's Model 6517B electrometer and Model 8009 resistivity chamber, the KICKSTARTFL-HRMA application automates volume and surface resistivity
measurements for accurate and repeatable results without the need for custom programming.
Previously, we have reported measurements of the temperature-dependent surface resistivity
of pure and multi-walled carbon nanotubes doped amorphous Polyvinyl Alcohol (PVA) thin films.
Also, different approaches in the measurement of concrete resistivity including bulk and surface resistivity
measurements are presented.
The surface resistivity
of the sample layer is increased with the increase of injection pressure, and the resistivity of subsurface and core decreases with the increase of injection pressure.
