    Abstract: Disclosed herein are methods for producing a poromeric synthetic leather having improved peel strength, the method comprising: preparing a polyurethane prepolymer, wherein the prepolymer comprises at least one isocyanate resin, and at least one polyol; preparing a first mixture comprising the polyurethane prepolymer, and at least one surfactant; preparing a second mixture comprising, the first mixture, water, and a chain extender; preparing a third mixture comprising the second mixture, at least one surfactant and a thickening agent, frothing the third mixture and thereby forming a frothed third mixture; applying the frothed third mixture to a fabric that is optionally impregnated with a polyurethane resin and thereby forming a coated fabric; optionally adjusting the thickness of the frothed third mixture on the fabric; and heating the coated fabric sufficiently to dry and cure it; wherein at least one nanoparticle is present in the polyurethane prepolymer, the first mixture, the second mixture, the third mixture, or combinations thereof. Leathers made according to such methods are also disclosed herein.
