Electrical behavior of a graphene/PEKK and carbon black/PEKK nanocomposites in the vicinity of the percolation threshold

Journal of Non-Crystalline Solids, 2019
Graphene and carbon black have been dispersed in a high performance thermoplastic polymer, the poly(ether ketone ketone), to improve its electrical conductivity. The dispersion of graphene has a significant influence on the percolation threshold. A simple exfoliation protocol to obtain graphene monolayers has led to a significant decrease of the ...

Controlling Crystallization: A Key Factor during 3D Printing with the Advanced Semicrystalline Polymeric Materials PEEK, PEKK 6002, and PEKK 7002

Macromolecular Materials and Engineering, 2022
AbstractControlling the crystallization of advanced, high‐performance polymeric materials during 3D printing is critical to ensure that the resulting structures have appropriate mechanical properties. In this work, two grades of polyetherketoneketone (PEKK 6002 and PEKK 7002) are used to print 3D specimens via a fused filament fabrication process.

Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

High Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.
