Carbon nanotube films have a wide range of applications and the industry needs to accelerate transformation and upgrading in the future.

Carbon nanotube film refers to a two-dimensional carbon nanotube network structure formed by filling a freely arranged carbon nanotube array through physical or chemical methods. Carbon nanotube film is a macro film structure formed by a single carbon nanotube (CNT), which is one of the subcategories of CNT (others include CNT powder, CNT fiber, CNT sponge, etc.).

Carbon nanotube films have excellent stiffness, strength, electrical conductivity, mechanics, thermal conductivity, tensile strength, wear resistance and chemical stability, and can be used in conductive films, semiconductor devices, flexible electronic devices, supercapacitors, It has broad application prospects in the fields of optical devices, electrochemical devices, lightweight high-strength composite materials, lightweight electromagnetic shielding, impact protection, aerospace and other fields.

According to the “2023-2028 Carbon Nanotube Film Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center , based on a variety of excellent properties, currently, carbon nanotube films have been widely used in flexible electronic devices, conductive films and other fields. Specifically, in terms of flexible electronic devices, carbon nanotube films can be used in manufacturing scenarios such as flexible sensors, flexible energy devices, and flexible conductive film materials. Currently, driven by the rapid development of the downstream market, the demand for carbon nanotube films continues to increase, and the industry’s prosperity continues to rise.

At the same time, with the development of end application markets such as new energy vehicles, aerospace, and power lines, the demand for carbon nanotube films continues to escalate, and lightweight, highly conductive, and large current-carrying materials have become the main trends in its upgrading. As a result, companies from various countries are actively developing high-end carbon nanotube film materials, and as research continues to deepen, some companies have made great progress.
