A method ( 10 ) for making a thread includes the steps of: mixing a polymer material and a solvent to form a solution ( 11 ); providing a liquid containing polar molecules, the liquid being insoluble in the solution ( 12 ); adding the solution to the liquid to form a solution film on a surface of the liquid ( 13 ); and applying an apparatus having a tip to the solution film for drawing out a thread therefrom ( 14 ). The solution can further contain an additive for improving one or more properties of the thread. The additive can be selected from nano-materials, for example, carbon nanotubes. The liquid containing polar molecules is water, or a solution having water as a solvent. The tip of the apparatus is needle-shaped.
