**7.8 CO2 laser supersonic drawing synthesis**

This technique is a novel method to develop long nano fibers by irradiation with CO2 laser at supersonic velocities. Melted fibers are gone through supersonic airflow to draw nano fibers in the range of diameters. Estimation of flow velocity is done by computer program. Through this process several natural and synthetic polymers are being used to yield nano fibers [47].
