Title of the Innovation: FLAME RETARDANT COTTON CLOTH

Brief About Innovation

FLAME RETARDANT COTTON CLOTH

ABOUT THE TECHNOLOGY

A novel flame retardant material phosphorus functionalized grapheme quantum dot (Pf-GQD), which is water based non-toxic, low cost, transparent and easy to coat on cotton fabrics by simple dip and dry technique has been developed. The cotton cloths and threads, coated with the developed Pf-GQD material, have been successfully tested for their flame retardant functionalities under steady state flame (T~1000 ^°C) and turbulent flame (heat flux ~ 30-40 kW/m²) conditions at the concerned laboratory collaboration facilities. A nominal thin coating (~4 μm) of the transparent solution of Pf-GQD on cotton cloth helps the cloth to retain its original colour as well as safety for daily personal use.

SALIENT FEATURES

Transparent and thin (~4 μ) coating on cloth makes it suitable for daily uses.
Highly efficient flame retardant property against large industrial fire (tested up to 50 kW/cm² heat flux).
Simple dip and dry coating method for application.
Non-toxic for human uses.
Potential to use as chemosensors, biolebeling and in photodynamic therapy.
Possibility of synthesis from natural carbon sources such as mango leaf.
