Nanotechnology – the prospects for the cable industry

» Posted in Other exotic places

Nanotechnology makes it possible to significantly move forward on ways to improve the performance of cable products, improving economic efficiency and simplify processes for their manufacture. What are the achievements of nanotechnology in the cable industry today?

Already used and potential applications of nanotechnology in the cable industry: stapling and fluoropolymers, carbon nanotubes and nanoclay as filler for fire cables, metal powders in conductive layers, superconductivity and Nanoceramics.

Production processes are considered in terms of creating a group of special cables, which can warn consumers about the faults and short circuits in your electrical circuits are able to eliminate the consequences in the event of injury or may be kept clean thanks to the coating that is resistant to contamination. An extremely attractive prospect of achieving high economic efficiency in the production of virtually every single cable or wire, of course, is of great interest, but at the same time involves a lot of problems. New nanomaterials should be environmentally safe and completely harmless to the environment. Cable industry, before which stood before the problem of development of new materials that can not afford to lag in this promising, emerging technology, despite all the difficulties that accompany the development of nano-materials for cable production.

Many materials exhibit fundamentally other physical properties that become apparent only at the level of nanometric size (less than 100 nanometers). It’s properties such as: electrical conductivity, heat capacity, the Young’s modulus, surface free energy, mechanical strength, etc. All these features can be used to create “smart cable” capable of responding to environmental conditions in a manner that is not available to traditional ” mute cable. ”

Nanotechnology is becoming increasingly popular, as is now there are tools to “see” and measure and manipulate matter at the nanoscale particles. Thus, the atomic force microscope is best suited for the characterization of nano-composite materials than the traditional electronic and optical microscopes. In addition, the atomic force microscope allows direct measurement of three-dimensional surface and to differentiate the types of materials at the surface level. It should be noted that many methods by ensuring that the nano-era, are more likely a continuation of the existing scientific achievement than the new, specially designed for the sole purpose of creating nanotechnology. Typical examples include materials such as Kevlar or Teflon. When both of these products came on the market, few have recognized this as a result of nanotechnology (it was called “Polymer Chemistry”), although it used the properties of materials at the nanoscale.

Traditionally, polymers were characterized solely by their bulk properties, including stiffness, strength, impact, elastic modulus, elongation, and mainly, the electrical characteristics. Since the block polymerization polymers were essentially homogeneous, characteristic of the substructure was not too important. But now it turns out to be important. Nanocomposite materials with new physical properties can be created by introducing small amounts of nano-additives.

Of great interest are the properties of nanocomposite materials and their ability to spread is not burning at very low levels of additives in the standard cable materials. For comparison: In order to achieve the appropriate level of flame retardance in polymeric compounds typically administered to 60% or more flame retardants (widespread – aluminum trihydrate or magnesium hydroxide). As a result, materials such as polyethylene, polyvinyl chloride and others acquire increased density, become less flexible, less resistant to water penetration and even create some problems for the extrusion process. In addition, as a result of the introduction of flame retardants are somewhat decreased the electrical characteristics of materials, they become more expensive, which limits their application.
