Predicting the Bending Size Dependency in Polymer Nanofiber Elasticity

Article Preview

In this paper, a strain gradient model is constructed to predict the bending size dependence of the elastic property of nanofibers under three-point tests. The model prediction shows that there are two kinds of size dependency for the bending tests: one is related to the diameter of the nanofiber, which can be named as Diameter Size Dependency (D-SD), the other is related to the length of the nanofiber, which can be termed as Length Size Dependency (L-SD). Mechanical testing on PCL nanofibers was performed to verify the model for D-SD, and good agreement is found between the model prediction and the data obtained in the experiment. The model can be applied to explain the size dependency in bending test for polymeric nanofibers.
