Misconceptions about filled polymers

Journal of Applied Polymer Science, 1974
The idea that, with filled polymers, length fraction, area fraction, and volume fraction of filler are different appears to have gained wide acceptance. The fallacy of this, except for special directions in ordered arrangements, is demonstrated. This misunderstanding has led to widespread misinterpretation of experimental results in this field.

Microwave characterization of filled polymers

Journal of Applied Physics, 2001
Interest in filled polymers has expanded in recent years as investigators have recognized the great flexibility allowed by these materials to suit particular properties such as electrical, mechanical, and/or coupling between these properties. This article describes the work undertaken to investigate the microwave response of two different types of ...

Model filled polymers

Polymer Bulletin, 1990
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.

Ductility of filled 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, 1978
Glass 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, 1994
The 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

2021
Recent 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
