  Abstract

The effect of graphene on mechanical properties and molecular structure of nylon 6 fibers was investigated by means of a simulation of molecular dynamics (MD) and an experimental design. Small quantities of graphene reaching 0.05 % by weight were mixed with nylon 6. Composite filaments were melt-spun and treated by drawing. The drawing experiments were designed using a Box-Behnken design, and the response surfaces of the tensile strength, initial modulus, and elongation at break of the drawn filaments were obtained. Mixing graphene increased tensile strength by 25 % to 7.2 g/d relative to the pristine nylon 6 filaments. The graphene strength and its orientation caused the increase in tensile strength, as revealed by the MD simulation. Drawing of the as-spun nylon 6/graphene composite filaments induced a crystal structure change from 款 to 慣 form and an increase in molecular orientation.
