Study the molecular structure of poly(ε-caprolactone)/graphene oxide and graphene nanocomposite nanofibers

- Reduced graphene oxide interacts more strongly than graphene oxide with PCL.
- Dynamic mechanical analysis presents information on nanofiber molecular structure.
- Molecular orientation enhances shrink force of electrospun mat at high temperature.
- Creep resistance of mats depends on PCL concentration and graphene loading.
