Applications of Nanoporous and Metamaterials: An Unornamented Review

Abstract

Materials with pore sizes less than hundred nanometres are considered nanoporous. Their organic/inorganic framework supports their porous nature, and the pores are filled with fluid. The pores of consistent shape and fixed diameter are essential for these materials in specific applications. They own certain magnetic, electrical, and optical properties, which signi-fy them in various applications such as signal transmission, energy, medicine, etc . Apart from natural nanoporous materials in existence, fabrication of materials with required melting point through combining polymers is possible. Materials, which are tailored to achieve unnatural electromagnetic properties like negative dielectric constant, negative refractive index, electromagnetic index, etc ., are known as metamaterials. They are microscopically built from conventional materials such as metals and die-lectrics like plastics. Some of the metamaterials may be nanoporous but not all. Metamaterials find significant applications in designing of antennas, cloaking devices, sensing devices, etc . In view of the importance related to nanoporous and metamaterials, some of their applications are reviewed to the possible extent.
