As anisometric nanostructured filler we used zinc oxide (ZnO), synthesized in RTU Institute of Inorganic Chemistry by plasma torch .
Incorporating impermeable anisometric particles in the polymer matrix forces the permeating molecules to wiggle around them in a random walk, hence diffusing through a tortuous pathway .
This allows the execution of all types of movements, thus all types of muscular contractions (isometric, anisometric and pliometric), with a well defined mechanical constraint.
ion in Il-Sm interstratifications, changes in particle morphology, TEM, SEM and HRTEM imaging, the role of water in the Sm-to-Il reaction, oxidation/reduction, compaction, dehydration, participation of non-clay materials, changes in the orientation of the anisometric components (by SEM), clay minerals in different microenvironment of the pore space, determination of Il-Sm and other structures using multispecimen X-ray diffraction profile fitting, determination of reliable and detailed structural models for mixed-layer minerals (MPFP = multi-specimen profile), oxygen isotope systematics, laboratory synthesis of clay mineral interstratifications, and on other themes.
Glass fibers and other anisometric fillers lead to a reduction in temperature-related expansion, but also to anisotropic material behavior.
The presence of highly oriented anisometric particles combined with the orientation of either the amorphous or crystalline phase imposes considerable undesirable anisotropy in in-plane shrinkages, which, in many cases, can lead to warpage and part deflection.
It is well known that interconnected structures with anisometric fillers result in an apparent yield stress which is visible in dynamic measurement by a plateau of G' versus G" at low storage modulus .
Most anisometric particles were detected in the blend compatibilized with SB1.
In addition, for a nanocomposite matrix, anisometric particles have been shown to hinder the coalescence process (4).
Stress overshoot is a nonlinear feature of anisometric filler containing systems, which is assumed to be the result of network structure break down and particle alignment that might accelerate the orientation and stretching of polymeric chains , .
Application of a strong shear field to a polymer melt with distributed anisometric filler particles aligns them along the shear direction and the matrix response dominates in viscoelastic properties of systems in whole (16), (23).
A promising direction in improving the mechanical properties of plasticized starch (PS) is the introduction of anisometric (fibrous or lamellar) particles of a filler.
The end result is a very efficient reinforcing effect, because clay layers are highly anisometric and a relatively small amount of clay gives rise to a very large number of particles, with a correspondingly large surface area.
To explain this behavior Krishnamoorti and Gianellis (7) proposed a microstructure composed of grains wherein the anisometric silicate layers are oriented in a preferred direction leading to grains boundaries and presence of defects.
The extent of modulus increase depends on particle size, shape, and orientation [25-27]; the anisometric shape of the wood flour used and the orientation of the particles determine composite stiffness.
