Polyelectrolyte complex coatings have been developed for flame-retardant fabrics, which demonstrate advantages in simplified operations and high flame retardancy. In this study, a polyelectrolyte complex coating (called PPM) was developed through the integration of H_3PO_3, hyperbranched polyethyleneimine, and montmorillonite, and was subsequently applied onto polyester/cotton fabrics using a one-step blade coating method. We thoroughly investigated the chemical structure, surface morphology, flame retardancy performance, thermal decomposition behavior, and mechanical properties of the coated fabrics. It was found that H3PO3 was incorporated into the PPM coating via ionic bonds, with a phosphorus atomic content of 0.9 %. Homogeneous and continuous coatings were formed on the surface of fabrics because of good film-forming ability of PPM. When the PPM loading was 15.3 %, the coated fabric showed a limiting oxygen index value of 64.9 % and quickly self-extinguished during the vertical flammability test with a damage length of 63 mm. In the cone calorimetry test, the PPM-coated fabric presented a 50 % reduction in peak heat release rate and a 52 % decrease in total smoke production. The PPM coating exhibited flame-retardant activities in both condensed and gaseous phases.
