Measurements of tensile modulus of carbon nanotube incorporated polymer nanofibers

We developed a simple method for the tensile properties of electrospun nanofibers by using a computerized spring-balance/step-motor setup. Calculation of total cross-sectional areas for each sample with vertically aligned nanofibers was readily done by SEM images and optical micrograph. The detailed setup and feasibility were described in the text. The tensile stress-strain curves of carbon nanotube incorporated polystyrene nanofibers were determined through this method, and characteristically consistent data, which was collected from each different sample, were successfully obtained.
