Surface Functionality through Periodical Patterning on Carbon Nanotubes

From their foundational role in electronics to their pivotal contributions in the structural domain, carbon nanotubes (CNTs) exemplify a revolutionary nanomaterial with broad applications. The chemical inertness of the CNT surface is a primary limitation that restricts the full utilization of CNTs for mass use in several applications. Herein, works performed on the development of surface‐modified CNTs known as periodically patterned structures are focused. Different structures including shish kebab, nanofiber, nanoflower, and cheetah skin CNT have been studied. Periodic patterning on CNTs offers a chance to improve the nanotube's surface properties and roughness, facilitating better interaction with a matrix. Additionally, the fully controllable processing procedure opens significant opportunities for additional modification and attachment of phases onto specific areas of periodically patterned CNTs. The periodic patterning aspect holds promise for the mass production of surface‐modified CNTs, enhancing their surface multifunctionality. This advancement has the potential to cater to a diverse array of applications, offering improved surface functionality in a mass‐production setting.
