    摘要： Disclosed herein are methods of producing externally stabilized, poromeric synthetic leathers having improved peel strength, the methods comprising: preparing a prepolymer from a mixture comprising at least one polyester polyol, at least one polyether polyol, at least one isocyanate and optionally in a solvent; mixing the prepolymer, water, and a first surfactant; optionally add a second chain extender to form a PUD; preparing a mixture comprising said PUD, at least one surfactant, and at least one thickener; frothing said mixture; applying the frothed mixture to a fabric and thereby forming a coated fabric; adjusting the thickness of the frothed mixture on the coated fabric; drying the coated fabric. Methods of improving the peel strength of poromeric synthetic leathers are also disclosed. Externally stabilized synthetic leathers having improved peel strength are also disclosed.

    摘要： Bioremediation geocomposite articles, and their method of manufacture, for treating (digesting) contaminants in soil or water. The bioremediating geocomposite mat includes a woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm. In the preferred embodiment, outer layers of the geocomposite article have a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material in at least outer portions of the thickness across its entire major surface(s) for better contact of the bacteria with contaminants held by the powdered or granular material. In the most preferred embodiment, liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the bacterial-containing geotextile article to prevent a powdered or granular material from escaping from the geotextile during transportation and installation.
