Mechanical Properties Of Nylon-6/sio_2 Nanofibers Prepared By Electrospinning

摘要

SiO_2 nanoparticles reinforced nylon-6 nanofibers were prepared by electrospinning of nylon-6/SiO_2 solution in formic acid. The effect of concentration and applied voltage on the diameter of the fibers was investigated. A nanoscale three-point bending test was used to evaluate the mechanical property of a single nylon-6/SiO_2 nanofiber. It was found that the elastic modulus of the nanofibers decreased with the increase in fiber diameter. This elastic modulus was in the range of 3.1-6.9GPa as the diameter ranged from 600 to 100nm.
