Temperature dependence of electrical properties in conductive polymer composites

Characterization of electrical properties of polymers for conductive nano-composites

Properties of various conductive nano-composites are dominated by quantum-level effects across small barriers created by the matrix material. The properties of the matrix clearly have a vital influence on the resultant behavior of the material. However, the quantification of the relevant matrix properties at the quantum level is difficult to measure using current techniques. This paper reports ...

Design of electrical conductive composites: tuning the morphology to improve the electrical properties of graphene filled immiscible polymer blends.

Polystyrene (PS) and poly(methyl methacrylate) (PMMA) blends filled with octadecylamine-functionalized graphene (GE-ODA) have been fabricated to obtain conductive composites with a lower electrical percolation threshold according to the concept of double percolation. The dependence of the electrical properties of the composites on the morphology is examined by changing the proportion of PS and ...

Temperature Dependence on Structural, Tribological, and Electrical Properties of Sputtered Conductive Carbon Thin Films

Conductive carbon films were prepared at room temperature by unbalanced magnetron sputtering (UBMS) on silicon substrates using argon (Ar) gas, and the effects of post-annealing temperature on the structural, tribological, and electrical properties of carbon films were investigated. Films were annealed at temperatures ranging from 400 °C to 700 °C in increments of 100 °C using a rapid thermal a...
