Interlocked CNT networks with high damping and storage modulus

Carbon, 2015
The interlocked carbon nanotube (CNT) networks formed by floating catalyst chemical vapor deposition method is found to show greatly enhanced damping ratio (0.37-0.42) and much higher storage modulus (>11.0 GPa) compared to most of engineering damping materials and any other kinds of CNT networks and composites ever reported. Interestingly, its damping

Peculiar frequency dependence of the storage modulus in a plastic disperse system

Food Research International, 2004
Abstract The frequency dependence of the storage modulus in a plastic fat was determined from stress sweeps at different frequencies, using a fresh sample at each frequency, rather than from the standard frequency sweeps at a fixed stress or strain.

Rheology of PVC Plastisol—V: Storage Modulus and Network Formed by Particle Contact

Journal of Colloid and Interface Science, 2002
Our previous work with PVC plastisols showed that pseudo-plastic behavior under increasing frequency of dynamic measurement was a result of the development of an immobilized layer. Subsequently, the dynamic viscosity and the storage modulus of the mobile phase were evaluated.

Predictive Models for Storage Modulus and Loss Modulus of Asphalt Mixtures

Journal of Materials in Civil Engineering, 2016
AbstractComplex modulus of an asphalt mixture constitutes two components: E′ representing the ability of the mixture to store energy (elastic behavior), and E′′ reflecting the capacity of the material to dissipate energy (viscous behavior). The main objective of this study was to develop predictive equations for the two components, E′ and E′′, to ...

MAPPING STORAGE MODULUS AND LOSS MODULUS OF POLYOLEFIN/POLYSTYRENE BLENDS WITH ATOMIC FORCE MICROSCOPY

Rubber Chemistry and Technology, 2012
ABSTRACT The storage modulus and loss modulus of blends of polypropylene/polystyrene and polyethylene/polystyrene have been mapped quantitatively with contact resonance atomic force microscopy. Contact resonance spectra were collected in Dual AC Resonance Tracking (DART) mode, in which the phase and amplitude are monitored at two discrete ...

Effect of electric field on storage modulus of dielectric composites

Journal of Applied Polymer Science, 2020
AbstractDCs composed by dielectric particles and elastomer matrix present electric field dependent deformation. Viscoelasticity dominates their electric field response, which has to be considered in their applications. Although the influence of strain amplitude and oscillation frequency on the viscoelasticity of DCs has been investigated, the effect of

Magnetic-Field Sensitivity of Storage Modulus for Bimodal Magnetic Elastomers

The Journal of Physical Chemistry B, 2016
The magnetic-field dependence of the storage modulus for bimodal magnetic elastomers consisting of carbonyl iron with a diameter of 2.8 μm (magnetic) and aluminum hydroxide with a diameter of 1.4 μm (nonmagnetic) was measured, and the effect of nonmagnetic particles on the magnetic-field sensitivity of the storage modulus was investigated.

Mullins' effect and the strain amplitude dependence of the storage modulus

International Journal of Solids and Structures, 1992
A micromechanically based continuum damage model for carbon black filled elastomers exhibiting Mullins' effect is extended to incorporate viscous response within the framework of a theory of viscoelasticity which includes the classical BKZ model as a particular case and is not restricted to isotropy.

Anisotropy in Storage Modulus of Magnetic Gels Induced by Magnetization

Japanese Journal of Applied Physics, 2004
The effects of magnetization direction on the complex modulus of magnetic gels, which consist of magnetized barium ferrite and poly vinyl alcohol, have been investigated. The modulus after magnetization showed anisotropy depending on the geometry of magnetization and strain direction.

Correlations of the first normal stress difference with shear stress and of the storage modulus with loss modulus for homopolymers

Journal of Applied Polymer Science, 1986
AbstractThe effects of temperature, molecular weight and its distribution, side chain branching, and the structure of polymers on the elastic behavior of bulk homopolymers were investigated, by using logarithmic plots of first normal stress difference (N1) against shear stress (σ12) and logarithmic plots of storage modulus (G′) against loss modulus (G″)
