Flame-retardant materials with more nanotechnology and less toxic chemicals

Abstract:
Firefighters and stuntmen certainly appreciate the fire resistant capabilities of modern textiles. Going far beyond such niche use, flame retardant materials have become a major business for the chemical industry and can be found practically everywhere in modern society. If you live in a country where houses are mostly built from wood (like in the U.S.; where, on the other hand, the things that used to be wood are now plastic - like christmas trees; flame retardant ones of course) most structural timber and wood elements such as paneling are treated to make them more fire resistant. Plastic materials are replacing traditional materials like wood and metal - just look at the toys you played with and the ones your kids have today. Unfortunately, the synthetic polymeric materials we group under the term 'plastic' are flammable. To decrease their flammability they require the addition of flame-retardant chemical compounds. The plastic casings, circuit boards and cables of your computers, electrical appliances or car are flame retardant. So is practically every material in airplanes, trains and ships from the fabric of seats to every kind of plastic structure found onboard. Name any plastic product and chances are it has been made flame retardant. Conventional methods for making plastic flame retardant involve a range of not exactly harmless chemicals. Improving the flame retardancy of polymeric materials without the use of toxic chemicals could now become possible thanks to the synergistic effect of carbon nanotubes and clay.
