Carbon Nanotube Films for Energy Applications

Abstract

This perspective article describes the application opportunities of carbon nanotube (CNT) films for the energy sector. Up to date progress in this regard is illustrated with representative examples of a wide range of energy management and transformation studies employing CNT ensembles. Firstly, this paper features an overview of how such macroscopic networks from nanocarbon can be produced. Then, the capabilities for their application in specific energy-related scenarios are described. Among the highlighted cases are conductive coatings, charge storage devices, thermal interface materials, and actuators. The selected examples demonstrate how electrical, thermal, radiant, and mechanical energy can be converted from one form to another using such formulations based on CNTs. The article is concluded with a future outlook, which anticipates the next steps which the research community will take to bring these concepts closer to implementation.

Lamination methods for the fabrication of perovskite and organic photovoltaics

“…As mentioned in the PSCs section, carbon materials, including SWCNTs, multi-walled carbon nanotube (MWCNT), graphene, and graphene oxide (GO), have been considered as the most promising alternative bottom and top electrode candidates in OPVs as well. 81,[164][165][166][167] In this regard, Kim et al transferred a transparent freestanding MWCNT (f-MWCNT) top electrode onto the n-i-p OPV device structure using a solution-assisted self-laminating process. 168 The as-prepared f-MWCNT sheets were manually deposited on top of the organic stacks, followed by immersion into an orthogonal liquid hydrofluoroether (HFE) solution to enhance the transparency and conductivity.…”

Design and characteristic analysis of flexible CNT film patch for potential application in ultrasonic therapy

“…Then, it induces a pressure gradient in the surrounding medium, hence emitting sound waves without any mechanical vibration. Unlike the conventional resonant transducer [29], the new TA transducer has various advantages, such as ultra-thin, flexible, oscillation-free (no self-vibration), wide frequency range, small size and lightweight [30][31][32]. Recent research indicates that the CNT film is able to produce higher sound pressure than the other TA nanomaterials [33], therefore it is a very promising candidate for fabrication of flexible ultrasonic therapy equipment.…”

“…In addition, it has become a research hotspot in the fields of electrical energy, thermal energy, and radiant energy. 2 Carbon nanotubes (CNTs) are a typical onedimensional nanomaterial with excellent mechanical, electrical, and thermal properties. [3][4][5] By spin coating, electrophoresis, vacuum filtration, chemical vapor deposition, and other physical or chemical methods, CNT arrays can be filled freely to form a twodimensional CNTF.…”
