Magnetic powder filled polymers
IEEE Transactions on Magnetics, 1994The composite magnetic materials with commercial polymer matrix along with different magnetic fillers have been studied, with the aim of tailoring their properties. The measured magnetic parameters of the prepared samples have been compared by those calculated using a model in which the magnetic powder particles are surrounded by the thin layer of ...

Heat conductivity of filled polymers
AIP Conference Proceedings, 2014The model of the filled polymer is considered. This model takes into account the following factors: the aggregation of particles of the filler; the interfacial layer. The numerical method of calculating the effective heat conductivity of composite systems is offered. The method consists in the direct solution of the heat conductivity equation.

Graphene Filled Polymers in Photovoltaic
2015Graphene—a two-dimensional lattice oriented monolayer of sp2-hybridized carbon atoms—has taken up considerable attention leading to a growing scientific interest due to its exceptionally high electrical conductivity (orders of magnitude higher than copper), optical transparency (>90 %), chemical robustness (more than 500 °C) and mechanical stiffness ...

Jamming in Filled Polymer Systems
Macromolecular Symposia, 2010AbstractAfter an introduction into the general characteristics of the jamming behavior, two filler flocculation experiments on a polycarbonate melt filled with multi‐walled carbon nanotubes and on a silica‐filled ethylene propylene diene monomer elastomer are presented. We propose that these experiments can be regarded as jamming phenomena.

1990
Published data, concerning the results of measuring rheological properties of polymer melts with rigid fillers, are discussed. The review is based mainly on the works of the 1980s. The effect of a filler's presence on three fundamental parameters of a material, namely yield stress, viscosity, and rubbery elasticity is considered.

Conformation of macromolecules in filled polymers
Polymer Science U.S.S.R., 1986Abstract A split plane densely packed with macromolecules is considered to be an appropriate model for interlayers in filled polymers. The structure of amorphous chains among the filler particles is assumed to be the same as the conformation of isolated Gaussian chains in critical conditions corresponding to the beginning of adsorption of chains from

Fatigue behaviour of filled polymers
Macromolecular Symposia, 1996AbstractThe fatigue resistance of any material is the combined resistance to crack initiation and then to crack propagation.1) In most of the cases, fillers act as strong cracks initiators. The Fatigue Crack Propagation can, under certain conditions, be improved (glass beads in epoxy) and this can be attributed to the crack front pinning mechanism ...

Model representation of filled polymers
Measurement Techniques, 1998We have investigated the mechanical properties and dielectric relaxation in polyamide-6 composites with fiber glass and mica. We propose a new model for filled polymers, assuming that the material consists of two interpenetrating continuous phases. The first phase is the polymer sorbed on the surface of the filler particles, mechanically stronger and ...

Fracture of particulate filled polymers
British Polymer Journal, 1978AbstractThe addition of particulate mineral fillers to polymers confers certain mechanical property improvements automatically. Stiffness increases, creep diminishes and distortion at elevated temperatures is often reduced. However, the fracture energy of a polymer, as measured in impact, cracking or tearing tests, may vary quite unpredictably when ...
