Abstract:

Electromagnetic shielding is presently considered very crucial for various electrical systems owing to the creation of electromagnetic pollution instigated by the alarming usage of electronic gadgets working at diverse frequencies and power levels. Conventionally used electromagnetic interference (EMI) metallic shields lack flexibility and hence cannot be considered as the right candidates for certain applications. This problem requires immediate attention because it causes drastic effects on the lifetime and performance of electronic devices and has an adverse effect on human beings as well. Rubber-based composite materials are regarded as suitable candidates for the fabrication of electromagnetic shields due to their combined electrical conductivity, interesting mechanical, and dielectric properties, elasticity to cover curved structures, and weather resistance for outdoor applications. This chapter aims to discuss the various fillers as well as elastomers used in the fabrication of elastomeric composites used in the preparation of EMI shielding devices. Finally a discussion of elastomeric blends used for shielding purpose will also be added.
