文章

Carbon nanotubes are materials that possess remarkable properties and offer extraordinary possibilities.

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.
