“…The as-prepared fabric was soaked into the solution, the pH of which was adjusted to 4-5 with sulfuric acid, at a liquor-to-material ratio of 1:50, and stirred for 2 h at 60 C. Sodium hypophosphite was used as a reducing agent. [30,31] The resulting Ni-P/MWCNTs-COOH/CF was cleaned with deionized water and dried at room temperature. Finally, a Ni-P/MWCNTs-COOH/CF material having a composite structure was obtained and the fabric became grey after electroless plating.…”

High‐electromagnetic‐shielding cotton fabric (CF) was prepared using carboxyl‐functionalized multiwall carbon nanotubes (MWCNTs‐COOH)/nickel–phosphorus (Ni‐P) electroless plating. Firstly, MWCNTs‐COOH was loaded on CF used to chelate the metal catalyst followed by electroless plating to impart outstanding electrical conductivity and electromagnetic shielding properties. The intermediate MWCNTs‐COOH layer not only improves the bonding strength via the chelating effect, but also can be used as a conductive material. This synergistic action of MWCNTs‐COOH and Ni‐P layer can work together to improve the electromagnetic interference shielding performance. The features of Ni‐P/MWCNTs‐COOH/CF were characterized using scanning electron microscopy, energy‐dispersive spectroscopy, X‐ray photoelectron spectroscopy and X‐ray diffraction. The resulting Ni‐P/MWCNTs‐COOH/CF fabrics show high surface resistance of 1.66 Ω sq−1 and robust electromagnetic shielding effectiveness of 40.2 dB. Furthermore, benefiting from the strong interface interaction, the as‐prepared composite fabrics retain stable performances after undergoing a series of physical and chemical tests, confirming promising practical applications even under harsh conditions.

Motivated by the increase of stress over electromagnetic pollution issues arising from the fast-growing development and need for electronic and electrical devices, the demand for materials with high electromagnetic interference (EMI) shielding performance has become more urgently. Considering the energy consumption in real applications, lightweight EMI shielding materials has been attentive in this field of research. In this chapter, first of all, the EM theory will be briefly discussed. Secondly, the EMI shielding performance and corresponding mechanisms of three categories of lightweight materials, such as polymer-based composites, foams and aerogels, are reviewed. Finally, the summary and conclusions of this field will be addressed.

The properties of three-dimensional networks of nanoparticles in polymer/carbon nanotubes (CNT) nanocomposites (PCNT) are particularly interesting from fundamental and application views. In this article, a new model is suggested for predicting the tensile modulus of PCNT using the Ouali and Paul models. The Ouali model considers the network of CNT in a polymer matrix, while the Paul model predicts the tensile modulus of samples containing dispersed nanoparticles. The predictions of the suggested approach are compared with experimental data from several samples. Also, the roles of the main parameters in the tensile modulus of PCNT are evaluated. The predictions agree with the experimental results at different filler concentrations. The roles of these parameters on the tensile modulus of PCNT are discussed based on the properties of CNT networks.
