DYNAMIC MECHANICAL AND RHEOLOGICAL STUDIES ON PS/ EXPANDED-GRAPHITE CONDUCTING COMPOSITES WITH LOW PERCOLATION THRESHOLD

摘要

One class of conducting materials is constituted of mixtures of other electrical conducting and insulating particles or electrical conductive particles incorporated in an insulating matrix. Dispersion of fillers and interaction between matrix and fillers play important role in composite properties. Thus, it is necessary to study relations between conductivity and dispersion and interaction. Relation of properties and interface of composites, which is important, is reported by many investigators.
