Nanofibers are long and thin cylindrical structures with diameters at nano-scale and lengths at micro-scale. The surface area of nanofibers is incredibly high compared to their same amount material at bulk state. For instance, the surface area of 1 gr gelatin increased to the area of 7 football fields when it is electrospun. Nanofibers with that high surface areas result the most effective outcomes, even more satisfied than predictions, for any given system they are used. Due to their high surface areas the interactions with the other molecules increase, leading to better stability and mechanical characteristics for the final product. For instance, the structure of car, plane or etc. containing carbon nanofiber has more mechanical strength. In addition, nanofibers may play an important role in sustainable systems with the efficient utilization of present sources due to fact that the systems containing nanofibers have less amount of raw material.
Surface properties of nanofibers can be easily tailored by process parameters during electrospinning. Their easily designed and tailored surface characteristics of nanofibers provide effective encapsulation and controlled release of active materials, filter membranes and textile products with high value added quality.
We produce nanofibers from natural or synthetic polymers or their mixtures (composites) depending on desired characteristics. Metals can also be added to polymers or composites for obtaining required properties in specific applications.
