Abstract
- Cotton fabrics (CF) with high flame retardancy and antibacterial performance are attracting more and more attention in the practical applications, e.g. home decorations. In this work, a novel Ag-mediated organic-inorganic phosphorus-hybrid coating (5BL/Ag-D) was developed using polyethylene imine (PEI)/ammonium polyphosphate (APP) polyelectrolyte bilayer and Ag-phosphoryl triazole complex (Ag D) via dip-coating method for flame-retardant CF with the antibacterial property. Interestingly, limiting oxygen index (LOI) of CF/5BL/Ag-D was sharply promoted to 33.5 % from 18.6 % of CF. Besides, CF/5BL/Ag-D could self-extinguish in the vertical burning test with afterflame time and afterglow time as low as 0 s. More importantly, as revealed in the cone calorimeter tests (CCT), the heat release involving peak heat release rate (PHRR) and total heat release (THR) of CF/5BL/Ag-D decreased from 193.8 kW/m2 and 14.8 MJ/m2 of CF to merely 16.7 kW/m2 and 3.2 MJ/m2, respectively. In addition, owing to the presence of Ag+, CF/5BL/Ag-D was endowed with the desired antibacterial property, and the bacteriostatic rates of CF/5BL/Ag-D on escherichia coli (E. coli) and staphylococcus aureus (S. aureus) were up to 94.7 % and 95.1 %, respectively. Moreover, the softness, the whiteness and the mechanical properties of CF/5BL/Ag-D were comparable to those of CF. In general, this work provides a promising approach to prepare Ag-mediated organic-inorganic phosphorus-hybrid coating for multifunctional cotton fabrics. • A novel Ag-mediated organic-inorganic P-hybrid coating (5BL/Ag-D) was developed. • PHRR and THR of CF/5BL/Ag-D decreased to merely 16.7 kW/m2 and 3.2 MJ/m2. • The bacteriostatic rates of CF/5BL/Ag-D on E. coli and S. aureus were 94.7 % and 95.1 %. • The whiteness and tensile strength of CF/5BL/Ag-D were enhanced with respect to CF.
