Applications electromagnetic shielding materials

Catalyst-assisted CVD processes can also be used to fabricate delicate microcomponents. Coiled fibres of carbon and refractory carbides are examples of such components which may be used in functional applications such as microsprings, microsensors and fillers of electromagnetic shielding materials. The microstructure of some coiled fibres is shown in Figure 3.39a. The device for the production of coiled fibre fabrication is shown in Figure 3.39b. A graphite plate substrate is placed at the central part of a horizontal CVD reaction chamber, and a metal... 

The application of palladium-catalyzed A -arylation reactions to the synthesis of polymers has attracted considerable attention due to the interesting electronic properties of these materials [6, 8, 11], For example, polyaniline has been utilized in anti-static materials, flexible electronics, and as electromagnetic shielding material. The first application of palladium-catalyzed amination reactions in polymer... 

Other Materials. The amount of plastic substrates plated in 1991 for both decorative and electromagnetic shielding applications was estimated to be about 4.3-5.4 x 106 m2 (13). 

Material science interest focuses on potential applications of its specific electronic and band structure. Metal-like conductivities, semiconductor properties, photoconductivity and the nonlinear optical features of URPAC samples suggest devices for electromagnetic shielding, energy storage, microelectronics, optoelectronic and optooptical communication or optical computing. 

Conducting polymer fibers were prepared by melt mixing and chemical coating on fibers. Different conductive materials were used in order to obtain conductive PP-based fibers with specific electrical and mechanical properties. The electrical conductivity and morphological characteristics of these fibers were investigated (Kim et al. 2004). The conductive fibers are intended for use in creating conductive yams, conductive fabrics (which can be used as electromagnetic shields), and multifunctional textile stractures for novel applications.
