Potential of Nanocellulose Composite for Electromagnetic Shielding

Composite Materials for Electromagnetic Interference Shielding

This paper demonstrates that the addition of chemical agents and carbon fibers to cement can greatly enhance the shielding effectiveness of the concrete. In addition to improving the shielding effectiveness, carbon fibers and chemical agents enhance the tensile and flexural strengths significant ly. As both carbon fibers and steel fibers are electrically conductive, both can be added to cement ...

Electromagnetic Shielding Property of Cfrp Composite Laminates

Emerging technology for shielding of electromagnetic radiation using composite materials

This study indicated that multi-walled carbon nanotubes (MWCNTs)-epoxy composites can be used as effective lightweight shielding materials. The measurement results showed that highest EMI SE of 23.4 dB at 8 GHz was obtained for nanocomposite with 1 wt% MWCNTs. Dielectric properties and electrical conductivity values were supplemented by microscopic studies.

Soy protein–nanocellulose composite aerogels

Organic aerogels based on two important and widely abundant renewable resources, soy proteins (SP) and nanofibrillar cellulose (NFC) are developed from precursor aqueous dispersions and a facile method conducive of channeland defect-free systems after cooling and freeze-drying cycles that yielded apparent densities on the order of 0.1 g/cm. NFC loading drives the internal morphology of the comp...

Surface Modification of Nanocellulose towards Composite Applications

The desire to develop high-value end-products derived from renewable resources is continuously growing as a result of environmental awareness and the depletion of fossil resources. In this context, nanocelluloses have gained great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of the present work was to investigat...
