| Abstract: |
Carbon nanotube forests condense when they are saturated with a solvent and then dried. While larger features readily condense into patterned features, smaller features require more delicate shrinking conditions and are highly de- pendant on temperature, solvent type, solvent vapor density, and heating rate. Through optimization of these parameters, nanotube forests can be success- fully densied so that they maintain their original patterns, simply becoming thinner and denser. Shrinking micrometer-scaled features allow us to use larger patterns to create extremely small features up to one hundred times smaller than the original features. |
