Cover Story: Layer-by-layer (LbL) deposition with phytic acid (PA), chitosan (CH), urea, and copper(II)sulphate (CuSO4) was used to obtain flame retardant and antimicrobial cotton. Limiting oxygen index (LOI) of cotton treated with 12BL of PA/CH-urea+Cu2+ was 26% and the sample passed VFT. Peak heat release rate (pHRR) obtained by microscale combustion calorimeter (MCC) showed a reduction of more than 61% as well as the reduction of the total heat release (THR) of more than 54% relative to untreated cotton. Antibacterial testing shows 100% reduction of gram-negative Klebsiella pneumoniae and gram-positive Staphylococcus aureus. LbL proved to be an ecologically-friendly multifunctional nanocoating and efficient alternative to commercial treatments.View this paper
