Preparation and properties of composition-controlled carbon nanofiber/phenolic nanocomposites

Composition-controlled carbon nanofiber/phenolic nanocomposites were designed and fabricated using a combination of powder stacking and compression molding techniques. The microstructure and composition distribution were evaluated. Experiments showed that their thermomechanical and viscoelastic properties were highly influenced by compositional gradient patterns of the nanocomposites. Electrical and thermal properties were able to be controlled from the surface to the core of the nanocomposites.
