Abstract

Abstract: Nanofibers of PCL/graphene composite were prepared by electrospinning the mixed suspension of PCL and graphene. The morphologies as well as thermal and mechanical properties of the as-prepared fibers were studied, and the result reveals that the structure and properties of the composites depend on the ratio of graphene to PCL, concentration, voltage, and distance of collection. The tensile strength and Youngs modulus increase by 486% and 660% when 027% graphene is added, and homogeneous nanofibers of composites can be obtained when the concentration of PCL is 11% (mass fraction), spinning voltage 28 kV, collect distance 35 cm, and spinning speed 6 mL/h.

Key words: electrospinning, PCL, graphene, nanofiber
