However, their strong tendency to form bundles or ropes due to strong van der Waals interactions prevents carbon nanotubes literature review utilization as the ultimate nanomaterial.

carbon nanotubes literature review short essay on history of internet

Proteins can interact with nanotubes with multiple types of interactions. Going further, the initial move toward viable support of polymers utilizing nano-fillers was to accomplish a uniform scattering of the fillers inside the facilitating network, and this was additionally identified with the as-blended nano-carbon structure.
