Polyphenylene vinylene (PPV) coated polystyrene (PS) beads which have moderate conductivity when doped were prepared by mixing monodisperse crosslinked PS beads, the surfaces of which had been sulfonated to render them anionic, with cationic PPV precursor polymers.

Journal of Applied Polymer Science, 1994
AbstractThe ductility of a calcium carbonate‐filled amorphous copolyester PETG in a uniaxial tensite test was examined as a fiction other filler volume fraction. A ductile‐to‐quasibrittle transition occurred as the volume fraction of filler increased. This transition was from propragation of a stable neck through the entire gauge length of the specimen

Particulate-filled glassy polymers
Journal of Applied Polymer Science, 1978Glass beads, NaCl crystals, or other imperfections act as stress concentrators in glassy polymers causing early crazing upon stressing. Stress–strain curves of glassy thermoplastic polymers filled with uncoupled glass beads or NaCl crystals exhibit a knee, or a slope-discontinuity point.

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 ...

Polymer-filled nanoporous membranes
2021Recent studies in our laboratory have demonstrated the effect of nanostructure on proton conductivity. In this study, oriented nanostructured polymer membranes were fabricatedby conjoining an ion conductive polymer with nanoporous host membranes, which have uniform pores aligned normal to the plane of the membrane. The hypothesis of research is that by

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 ...
