Dielectric monitoring of carbon nanotube network formation in curing thermosetting nanocomposites

Dielectric monitoring of carbon nanotube network formation in curing thermosetting nanocomposites

This paper focuses on monitoring of carbon nanotube network development during the cure of unsaturated polyester nanocomposites by means of electrical impedance spectroscopy. A phenomenological model of the dielectric response is developed using equivalent circuit analysis. The model comprises two parallel RC elements connected in series, each of them giving rise to a semicircular arc in impeda...

Design and characterization of carbon nanotube nanocomposites

Revolutionary design concepts in future aerospace vehicles will depend on extraordinary material properties to permit significant reduction of mass and size of components, while imparting intelligence. Due to their combination of remarkable electrical and mechanical properties, carbon nanotubes (CNT) are expected to enable this paradigm shift in design concepts. However, significant challenges ...

Gold-carbon nanotube nanocomposites: synthesis and applications

Nanocomposites are combinations of nanomaterials with other molecules or nanoscaled materials, such as nanoparticles or nanotubes. In general, these novel nanocomposites have different physical and chemical properties from the constituent particles or wires, and will thus allow new kinds of applications. Among these nanocomposites, gold-carbon nanotube (AuCNT) composites are of particular inter...

Superhydrophobic carbon nanotube/silicon carbide nanowire nanocomposites

a r t i c l e i n f o The composite film of carbon nanotubes and silicon carbide nanowires was synthesized directly on the silicon substrate by the catalyst-assisted method. The carbon nanotubes crimped together decorated with silicon carbide nanowires covering the whole substrate. The appropriate amount of aluminum powders is a crucial factor to achieve the composite film. The composite film e...
