The biocompatibility, controllable size and crystal structure and surface functionalization ability of TNTs accelerate its efficient development in biomedical applications including implants and biosensors.

Templateless Electropolymerization for Controlled Growth of Polymeric Nanotubes on Micropatterned Surfaces

“…The fabrication of substrates with controlled wettability properties is extremely important for various potential applications such as in liquid transportation, water harvesting or oil/water separation membranes. A promising way to control such properties is to mimic phenomena observed in Nature . For this purpose the understanding of the relationship between the surface properties of new materials and their micro‐and nano‐scale structural parameters is fundamental to ensure generation of well‐controlled surface structures.…”

“…Recent works show that high surface‐area‐to‐volume ratio, densely packed nanotubes deposited on surfaces have shown exceptional properties for potential applications such as surface adhesion, sensors, optical devices, drug delivery, or cell growth …”

“…Recent works show that high surface-area-to-volume ratio, densely packed nanotubes deposited on surfaces have shown exceptional properties for potential applications such as surface adhesion, sensors, optical devices, drug delivery, or cell growth. [1][2][3][4][5] The most common method to prepare extremely ordered porous structures like vertically aligned nanotubes is based the use of hard templates such as anodized aluminum oxide (AAO) membranes. [6][7][8][9][10] However, the main drawback of such approach is that it needs a multi-step process to obtain nanotubes and each nanotube characteristics requires the use of different membrane which complicate the implementation.…”

Formation of Nanofibers with High Water Adhesion by Electrodeposition of Films of Poly(3,4‐ethylenedioxypyrrole) and Poly(3,4‐propylenedioxypyrrole) Substituted by Alkyl Chains

“…Hence, two key parameters can highly influence on the surface hydrophobicity and the water adhesion: the surface energy and the surface structuration/roughness. Various processes can be used to control these two parameters, including chemical etching, hydrothermal processes, plasma treatment, laser treatment, chemical vapor deposition, anodization, use of nanoparticles/nanocomposites, lithography, and templating . Conducting polymers can be used to obtain nanostructured materials .…”
