Multifunctional Cotton Non-woven Fabrics Coated with Silver Nanoparticles and Polymers for Antibacterial, Superhydrophobic and High Performance Microwave Shielding

The explosive progress of electronic devices and communication systems results in the production of undesirable electromagnetic pollution, known as electromagnetic interference. The accumulation of electromagnetic radiation in space results in the malfunction of commercial and military electronic appliances, and it may have a negative impact on human health. Thus, the shielding of undesirable electromagnetic interference has become a serious concern of the modern society, and has been a very perspective field of research and development. This paper provides detailed insight into current trends in the advancement of various polymer-based materials with the effects of electromagnetic interference shielding. First, the theoretical aspects of shielding are outlined. Then, the comprehensive description of the structure, morphology and functionalization of the intrinsic conductive polymers, polymers filled with the different types of inorganic and organic fillers, as well as multifunctional polymer architectures are provided with respect to their conductive, dielectric, magnetic and shielding characteristics.

The military and industry have multiple needs for Electromagnetic interference (EMI) shielding textiles, but it is still a huge challenge to realize integration of inorganic nanomaterials and fabric with good interface adhesion. Therefore, carefully chosen EMI materials and preparation techniques are key to provide commercially acceptable fabrics. Herein, a flexible and durable EMI shielding cotton fabric was fabricated by a layer-by-layer assembly of multiwalled carbon nanotubes (MWCNTs) and nickel ferrite (NiFe2O4) nanoparticles, following by an organic poly (dimethylsiloxane) (PDMS) coating. Benefiting from the strong interfacial interactions between MWCNTs and NiFe2O4, the efficient electrical, magnetic and thermally conductive pathways were successfully constructed on the cotton fabric.
The resultant composite fabrics exhibited high electrical-magnetic properties, superior EMI shielding effectiveness of ≈ 84.5 dB in X-band with a 0.96 mm thickness, and markedly enhanced thermal conductivity (2.52 W m− 1K− 1). Furthermore, the external PDMS coating not only imparted a water-resistant feature, but also improved the structural and performance stability while maintaining satisfactory air permeability. Based on these results, the layer-by-layer assembly approach can be viewed as an efficient tool to fabricate protective textiles against EMI radiation pollution. A new surfactant assisted acid prehydrolysis process for enhancing biomass pretreatment.
