Moreover, a comparison study showed that elastic modulus determined with quasi-static experiments was greater than storage modulus calculated with dynamic mechanical experiments.
It is concluded that the NCs reinforced by long nanofiber possess greater storage and loss modulus than the NCs owing short fiber.
In addition, the specific stereocomplex interaction in the interphase of PLLA matrix and modified CNC particles results in great improvement of both storage modulus and the heat distortion resistance of the PLLA/CNC-g-PDLA nanocomposites.
At concentrations of lithium hydroxystearate greater than 5% by volume, the storage modulus, G′, was found to be greater than the loss modulus, G″, with both moduli increasing with increasing thickener concentration, below this critical concentration G″ was greater than G′.
Good dispersion of the clay layers gave the PPCN greater thermal stability and an enhanced storage modulus, which indicated a reinforcing effect of the clay in the PP matrix.
For all the formulations tested, the storage modulus (G′) values were greater than the loss moduli (G ′′), indicating the hydrogels were chemically cross-linked.
The results show the viscoelastic film thickness has a greater influence in the loss factor than in the storage modulus, being this effect more pronounced at high frequencies.
It was found that annulus and fibrous had similar storage modulus and loss modulus, which were greater than the nucleus.
A high content of guluronic acid resulted in a storage modulus that was almost three times greater than for the formulation with lower guluronic acid content in the case of gels formed using strontium alginate dispersions.
As can be seen, the storage modulus G′ is almost independent of frequency and greater than loss modulus over the whole frequency range.
