✦ Synopsis

Most 5re retardant nanocomposites are made from layered silicates and organic polymers, a variety of methods are used in their synthesis.

The mechanism for the 5re retardancy of these composites is generally considered to be due to the structure of the char formed during combustion, which enables the char to thermally insulate the polymer and inhibit the formation and escape of volatiles during combustion.

Fire retardant nanocomposites require relatively low concentrations of silicates for activity, resulting in low additional costs and weight. Improvements in the bulk physical properties of the polymer can be additional advantages over traditional 5re retardants.

## Abstract Owing to their low cost phosphorus fire‐retardants find vast application in making fire‐retardant cellulosic compostions. They have been used both as a physical additive as well as part of the polymer structure. Acid forming phosphorus compounds are generally effective in cotton and oth

Full-scale 5re experiments were carried out in an ISO room to study the behaviour of commonly used cellulosic lining materials in real 5re conditions. In addition to the temperature measurements recommended by the ISO 9705, temperature recordings were made at each node of grid lines on the wall lini
