碩士 === 國立交通大學 === 機械工程系所 === 96 === In this thesis, PVP ( Polyvinylpyrrolidone ) was selected as the material, and a modified traditional electrospinning device was arranged to fabricate the helical nanofiber. This device is composed of a side-by-side syringe. Each syringe was filled with marcormolecular compound with different electrical conductivity, the fiber contracts at one side because of the difference of the electricity thus produces fibers of helical shapes. We can control the fiber’s shape by adjusting the electric conductivity of the macromolecular compounds. The helical structural of the nanofibers is similar to the mechanical spring, since the helical structure can store energy such as external force or torsion when it is compressed. The helical structure of nanofiber also have a pontential used to be applyied to the micro structures.
