A Slovenian research institute offers a method for rapid deposition of uniformly distributed and vertically oriented carbon nanowalls (CNW). The method provides industrially relevant deposition rates of the carbon nanowalls, synthesis is highly controllable and scalable to large surfaces. Companies from the field of fuel cells, photovoltaic devices, lithium ion batteries and sensors of specific gaseous molecules are sought for license agreement.

 

Description     

Carbon nanowalls (often called “vertically oriented multilayer graphene sheets") are materials of carbon-containing structures with a thickness up to several nm and height between about 100 nm and 100,000 nm. Usually they are formed in a dense array and extend substantially perpendicular from the surface of a substrate. Quite often their orientation is random and they form a network. As a consequence, a very large surface area with superior electrical and chemical properties is established (e.g. compared to smooth carbon materials). Such materials show a potential for use where large surface-to-mass ratios are needed like in fuel cells, lithium ion batteries, photovoltaic devices, thin-film transistors, sensors of specific gaseous molecules, field-emission devices, batteries, light absorbers, enhanced detectors for electrochemical and gas sensors, electric double layer capacitors and scaffolds for tissue engineering.

 

Various methods can be used to synthesize carbon nanowalls. Common features are use of vacuum systems or reaction chambers under low pressure. Hydrogenated carbon precursors are used to facilitate growth of carbon nanowalls through decomposition upon plasma conditions and depositing on a substrate, where elevated temperature of the substrate is essential. Addition of hydrogen proved to be relevant for a good quality of carbon nanowalls. Main obstacles these techniques have, are (1) low deposition rates (around 1 nm/s) due to deposition of carbon from CHx radicals, (2) requirement to constantly supply hydrogenated carbon precursor and (3) use of hydrogen.
