Abstract

The polymer coating protects materials from failure due to environmental changes and improves their stability and performance towards electromagnetic radiation shielding. In the current investigation, acrylic polymer (AP) was coated with varied ratios of graphene (GR) nanoparticles or co-coated with GR and 5 wt% carbon fiber (CF) via the casting method. The FTIR and SEM results demonstrated excellent coating and interaction between AP, GR, and CF. The water contact angle increased from 45.5° for pure AP to 55.8° and 68.4° for AP/2wt%GR and AP/GR/5wt%CF, respectively. The thermal conductivity was increased from 0.226 Wm⁻¹ K⁻¹ for AP to 0.268 Wm⁻¹ K⁻¹ and 0.344 Wm⁻¹ K⁻¹ for AP/2wt%GR and AP/GR/5wt%CF, respectively. The AP/GR composites and AP/GR/CF hybrid composites outperformed AP in terms of electromagnetic irradiation shielding efficiency, which improved with frequency. Coating with GR and GR/CF increased the relative permittivity, electrical conductivity, F-factor, and other dielectric constants, but decreased as the frequency of the applied AC voltage increased. The synthesized AP/GR/CF hybrid composites may be suitable for various technologies i.e. telephone microwave, TV image transmission, and weather radar.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
