Hydrogels and aerogels of carbon nanotubes

Abstract

Aerogels and hydrogels are materials having high surface area, adsorption capacity, and mechanical properties. These gel materials are employed in various fields such as water electronics, smart materials, drug delivery, biomedicine, etc. Carbon nanotubes are much famous for their extraordinary mechanical strength and aspect ratio. Incorporation of carbon nanotubes (CNTs) generally impart enhanced properties to the matrix. CNTs can be employed in the fabrication of aerogels and hydrogels, and the resultant materials can be employed in various applications. The chapter discusses in detail about the basics of hydrogels and aerogels, their structure, properties, and applications.
