Carbon Nanofiber Composite----Synthesis and Characterization
Abstract
Carbon nanofiber (CNF) composites with light weight, sustainability of large deformation, chemical stability, corrosion and fatigue resistance, and vibration and noise reduction capability can have positive impact on a wide range of applications. To improve processing control and reproducibility for large scale engineering applications, cost effective carbon nanofibers (CNFs) in form of interconnected porous network structure were used as nanofillers. Processing, microstructure, mechanical, electrical and thermal properties of carbon nanofibers reinforced polydimethylsiloxane (PDMS) have been studied. Mechanical measurements on the composites show that the CNF-PDMS interfacial bonding can be until failure, interfacial debonding happens in the CNF-PDMS composites and the resulted permanent deformation stabilizes with increasing load-unload cycles with significant energy dissipation. Electrical measurements show the current density and temperature did not affect too much on this composite. And this composite has electrical recoverability and this ability relates to strain history. Thermal measurements show the thermal conductivity of pristine CNF composite is 20% larger than pure PDMS.
