Morphology and Properties of Flame-Retardant Superhydrophobic Polymer Coatings Deposited on Cotton Fabrics from Supercritical CO₂

An approach for deposition of a multifunctional coating on the surface of cotton fabric using supercritical carbon dioxide (sc CO2) is explored. Polyphosphazene-based microspheres to be used for deposition are synthesized, and their thermal behavior is studied using thermogravimetric analysis. The morphologies of hydrophobic polymer and polyphosphazene microspheres deposited on cotton fibers from acetonitrile and from sc CO2 are compared using...
