Synthesis of a smart coating for furniture textiles

Wednesday, 21 June 2017

Smart coatings for furniture textiles should be flame retardant and hydrophobic. Can a novel functional coating, developed with an environmentally friendly method, meet these requirements?

The coating was prepared based on commercial binder and graphite with incorporation of ammonium phosphate and N-[3-(trimethoxysilyl)propyl]-ethylene diamine.

Enhanced hydrophobicity and tensile strength

The TiO2 nanoparticles were further dispersed in the coating and decorated in graphite platelet. Mass ratio of ammonium phosphate was varied and their effect was studied. The flammability, thermal and mechanical properties of the treated furniture textiles were evaluated and improved. Rate of burning of developed textile was significantly reduced recorded 0 mm/min compared to 118 mm/min for blank sample. Also, the tensile strength of coated textile was improved by 40%. This is in addition to enhancement in hydrophobic properties of treated textile surface achieving 145° water contact angle.

The study is published in: Progress in Organic Coatings, Volume 110, September 2017, Pages 204–209
