where [[lambda].sub.c], [[lambda].sub.m], and [[lambda].sub.f] are the thermal conductivities of the composite, matrix, and filler, respectively, and [[PHI].sub.f] is the volume fraction of filler.
In this study, the measured thermal conductivities of several polyolefin composites separately filled with two thermal conductive particles are quoted from literature to preliminarily verify this thermal conductivity equation, such as medium density polyethylene composites, polypropylene composites, and epoxy composites.
The thermal conductivities of sandstones may have a linear relationship with the degree of saturation (Fig.
The order of increment in thermal conductivities was as follows: CK < CS [approximately equal to] KB < NB, starting from an increment of 13% to 27% and finally 52%.
The relationship between conductivities of ionic liquid and temperature followed Arrhenius equation [9], which is described as
Conductivities are given here in units of S/cm, which is equivalent to 1/ohmcm.
Signal processing techniques integrated in the new approach include the use of adaptive wave forms, dynamic signal compensation and adaptive noise suppression, providing highly accurate measurements over an extraordinarily wide range of sample conductivities.
The incorporation of LiC[F.sub.3]S[O.sub.3] salt, DBP plasticizer, and Zr[O.sub.2] nanofiller has led to significantly enhanced ionic conductivities. The composition of PEO + LiC[F.sub.3]S[O.sub.3] + DBP + 0.05 wt.% Zr[O.sub.2] exhibits the highest conductivity, (1.38 x [10.sup.-4] [Scm.sup.-1]), compared with the conductivity of pure PEO (1.58 x [10.sup.-9] [Scm.sup.-1]) and PEO + LiC[F.sub.3]S[O.sub.3] (9.24 x [10.sup.-6] [Scm.sup.-1]).
It was found that when critical exponent is low and volume fraction is high, high electrical conductivities are established.
On a large scale, it depends on the average thermal conductivities parallel and perpendicular to bedding and on the dip of bedding [THETA] from the surface.
The mean conductivities determined at each time period are shown in Fig.
Free electrons are responsible for electrical and thermal conductivities of alloys in solid and liquid states.
