Synthesis and Parametric Investigation of Nanofibers

Nanotechnology has attracted the attention of the researchers due to their surface area to volume ratio. Addition of any nano materials in form of nano particle, fibers, tubes, flakes etc has enhanced the material properties. Here we have the parameters which affects the dimension and properties of the nano fiber. The polymer nano fibers can be produced by using various processing techniques like drawing, self assembly, template synthesis, phase separation, electrospinning etc. Out of these processing techniques electrospinning is a best way to produce a polymer nano fiber with small diameter (10 nm to 1500nm). Due to large length to diameter ratio and small mass to volume ratio these nano- size fibers has many application in industry. The parameters affecting fiber diameter and properties can be varied by adjusting the concentration of the polymer solution, distance from tip to collector, applied electric field, flow rate, viscosity, surface tension, electrical conductivity of solution and temperature of solution, Ionic salt addition, And Molecular weight etc.
