Physica A: Statistical Mechanics and its Applications, 1989
Abstract We review the electrical properties of polymers filled with conducting particles of various sizes and shapes. dc and ac experimental behaviors in the neighborhood of the familiar insulator to conductor transition are generally in fair agreement with the predictions of percolation theory.

Viscoelastic Properties of Filled Polymers
International Journal of Polymeric Materials and Polymeric Biomaterials, 1972Abstract Rheological properties of carbon black filled polyisobutylene samples (of low and high molecular weight) have shed light on the relationship between the behaviour of disperse and polymeric systems. At sufficiently high filler concentration a structural skeleton seems to appear. This affects the properties.

Rheological properties of filled polymers
Macromolecular Symposia, 1996AbstractThe rheological properties of two model suspensions using a Newtonian polymeric matrix are presented and discussed in light of results presented in the literature. It is shown that particle‐particle interactions in concentrated suspensions are responsible for a gel‐type behavior at very small strain and strain hardening at a critical strain ...

Macromolecular Symposia, 2001
It is tried to examine briefly all the aspects of filler interactions with polymer ageing, including direct chemical (catalysis of degradation, stabilising effects) and physical (screen and thermooptical effects, modification of transport properties) interactions as well as indirect ones such as stabiliser trapping, influence on the rate of mechanical ...

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 ...

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.

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 ...

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.

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 ...
