The employment of nanofillers for the enhancement of flame retardant of cotton fabrics was limited by the weak adherency, which is usually deal with additional adhesive coating. This paper investigates the adhesive of polydimethylsiloxane (PDMS) from the mesoscopic perspective, illustrates the adhesive mechanism of PDMS basing on the three key features: the binging energy, the radial distribution function, and hydrogen bond. Furthermore, based on the mesoscopic feasibility analyze, h-BN as well as the adhesive agent PDMS/PDA coating was fabricated to obtain the flame retardant cotton fabric. Comparing the Scanning electron microscopy and ATR-FTIR demonstrated that the flame retardant coating was successfully constructed on the substrate. The thermogravimetric analysis (TGA) and cone calorimeter (cone) confirmed the enhanced thermal stability and flame retardancy. The mesoscopic simulation and thermal analyze experiment (Scanning electron microscopy,ATR-FTIR,TGA) show PDMS employs a favorable adhesion agent for obtaining the better distribution state of h-BN than that of PDA-connected sample, which is responsible for improving flame retardancy.
