- Abstract
The aim of this study is to investigate the effect of carbon nanotubes on the electromagnetic shielding and electrical conductivity of polyetheretherketone(PEEK). The modified multi-walled carbon nanotubes (mMWCNT) was prepared using cetyltrimethylammonium bromide (CTAB) as a dispersing agent. The PEEK/mMWCNT composits were prepared by the processing technology of wet mixing and extrusion blending. The results showed that the mMWCNT were well-dispersed in PEEK matrix, which provided strong support for improving the mechanical and electrical properties of the composites. When the mMWCNT mass fraction was lower than 2.0%, the mechanical properties of PEEK/mMWCNT composites were significantly improved. The mMWCNT formed a 3D network with good conductivity in PEEK. In terms of electromagnetic shielding performance, the total electromagnetic shielding efficiency of PEEK/mMWCNT composites ranged from 3.35 dB to 24.47 dB, which indicated a good absorption of X-band electromagnetic waves. This study confirmed that PEEK/mMWCNT composites have superior electrical conductivity and electromagnetic shielding properties. Hence, the composites have a wide application potential in electronic equipment, communication technology and military protection.
