IISER Kolkata Researchers develop flame-proof, rust-resistant material
Researchers from Indian Institute of Science Education and Research (IISER), Kolkata have developed an organic-inorganic molecular hybrid material which is fire and rust resistant.
The hybrid material was synthesised by combining polyhedral oligomeric silsesquioxane (POSS) and diphenylalanine. Both POSS and diphenylalanine are naturally water repelling, and when they are combined together the hydrophobic nature further gets enhanced. The POSS has unique properties such as high thermal stability and fire retarding ability.
The hybrid material is colourless and does not react with metal. It also inhibits bacterial growth and make coated material such as wood or paper fire and flame proof. It also increases the mechanical strength of the coated paper 1.5 times
Nails coated with the material can resist corrosion even when treated with highly corrosive aqueous solution of sodium chloride, sodium bromide, potassium chloride and hydrochloric acid. Paper or other materials coated with it can behave similar to the lotus leaf and keep the surface clean and completely water-proof.
The hydrophobic nature of the hybrid material can protect artefacts from corrosion and environmental pollution. Moreover, its fire-resistant property can prevent plenty of fire accidents.
