Abstract

The method of fabricating composites composed of a glass micro ber matrix and the conductive nano bers is proposed. The nano bers incorporating single-walled carbon nanotubes (SWCNTs) and an organic material are spread over the surface of glass micro bers and in some areas between micro bers are coupled together into a branched network. The contributions of intra- CNT and inter-CNT conduction mechanisms in the composites with different contents of SWCNTs are evaluated from the analysis of their impedance spectra. The crossover between two conduction mechanisms is observed at a content of SWCNTs of about 0.1 wt. %.

Carbon nanotube

A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometer range (nanoscale). They are one of the allotropes of carbon. Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometers, about 100,000 times smaller than the width of a human hair. They can be idealized as cutouts from a two-dimensional graphene sheet rolled up to form a hollow cylinder. Multi-walled carbon nanotubes (MWCNTs) consist of nested single-wall carbon nanotubes in a nested, tube-in-tube structure.

Spectroscopy

Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Composite material

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.
