Abstract

See full text

A simple controllable set-up for drawing single filament nanofibers from polymer solutions or melts using a rotating rod or a set of rods (round brush) is described. The set-up can be assembled in a few minutes and applied to fabricate customized nanofiber scaffolds and meshes for various applications. The resulting fiber diameter is controlled precisely in the range 40 nm to 5 μm by adjusting the rotational speed and polymer concentration. Owing to the simple design and capability to manipulate single nanofibers, the spinning set-up can be used to wind a single filament into unidirectional, orthogonal or randomly oriented 2D and 3D meshes with controlled density, thickness and combinations of different fibers and materials in the scaffolds. The method is scalable and can be implemented easily for laboratory and industrial manufacturing.
