New lengthy nanofibers developed
5 February 2008Min-Feng Yu, a mechanical science and engineering professor at the University of Illinois and graduate students Abhijit Suryavanshi and Jie Hu developed a three diamensional lengthy nanofiber. The research paper has been accepted for publication in the Journal Advanced Materials.
According to the researchers the process is similar to a drawing with a fountain pen. As soon as the ink come out of the fountain pen it solidifies and in a similar approach, the researcher developed three diamensional nanofibers. A micropipette of 100 nanometer aperture was connected to the reservoir and as soon as the micropipette was brought close to the substrate, a small amount of ink will rise in the micropipette.
After removing the micropipette, the solvent quickly evaporates out and thus allowing solute to nucleate and precipitate to form a lengthy nanofiber. For drawing lengthy nanofiber, researchers used a precision spinning process and they were able to create a nanofiber of approximately 850 nanometer in diameter and 40 centimeter long.
