ABSTRACT
The nanomaterials of various forms such as nanoparticles, nanofibers, and nanofilms are extensively employed in various manufacturing sectors such as energy systems, construction of parts, biomedical devices, chemicals, electronic sensors, agricultural fields, aerospace, automotives, paints, and cosmetics. General oxidative stress can also occur when nanomaterials enter the body. Carbon nanotubes (CNTs), discovered only 20 years ago, are perhaps the most widely known and used nanomaterials due to their carbon bond interactions producing hexagonal lattice structures in which each atom bonds with three others, leaving an extra electron per atom to reinforce the bonds. The CNTs gain much attraction in the aerospace industry as the carbon nanotubes along with the composite materials can be fastened to obtain the material considerably tougher, impervious to damage, and great strength on comparing to other advanced composites. Composite manufacturing, even in the absence of nanomaterials, involves a hazardous work environment.
