Frequency-dependent electrical mixing law behavior in spherical particle composites
The electrical properties of cement-based composites with mono-size conductive (steel) or insulating (glass) spherical inclusions were investigated by combined 2-point impedance spectroscopy and 4-point dc resistance measurements. The matrix was ordinary Portland cement (w/c = 0.4; cured for 7 days). Particle loading was varied over an extended range to as high as 42% volume fraction. The steel...
متن کاملFrequency-Dependent Acoustics of Composites with Interfaces
We study the scattering of an incident wave by a composite medium with periodic microstructure in a slab geometry. We compute the expansion on the wave field in powers of the parameter = d/λ, where d is the characteristic scale of the microstructure and λ is the wavelength. For ε = 0 this corresponds to homogenization theory. Here, we focus on the correction terms for ε > 0 and compute the freq...
متن کاملElectrical behavior and positive temperature coefficient effect of graphene/polyvinylidene fluoride composites containing silver nanowires
Polyvinylidene fluoride (PVDF) composites filled with in situ thermally reduced graphene oxide (TRG) and silver nanowire (AgNW) were prepared using solution mixing followed by coagulation and thermal hot pressing. Binary TRG/PVDF nanocomposites exhibited small percolation threshold of 0.12 vol % and low electrical conductivity of approximately 10(-7) S/cm. Hybridization of TRGs with AgNWs led t...

15 صفحه اولPhotopiezoelectric composites of azobenzene-functionalized polyimides and polyvinylidene fluoride.
Light is a readily available and sustainable energy source. Transduction of light into mechanical work or electricity in functional materials, composites, or systems has other potential advantages derived from the ability to remotely, spatially, and temporally control triggering by light. Toward this end, this work examines photoinduced piezoelectric (photopiezoelectric) effects in laminate com...
