A method of plating a metal on a hydrophobic polymer, especially in the shape of small particles, involves: (a) contacting a surface of hydrophobic polymer substrate with a polycation such as poly(allylamine hydrochloride) to create a treated surface; (b) contacting the treated surface with a catalyst; and then (c) immersing the surface in a electroless metal plating bath to create a coating of metal on the surface. Metals include copper, silver, gold, nickel and cobalt. Catalysts are selected from compounds containing palladium, platinum, tin, copper, or nickel salts. Damaging surface treatments such as etching by plasma or acid are avoided.

Methods for coating metals on hydrophobic surfaces

Methods and devices for treatment of biomass comprised of crystalline structures are described that provide a combined mechanical, chemical and thermal effect (i.e., nano-hybrid pretreatment) to synergistically break down the crystalline structures. Such nano-hybrid mixing provides efficient, and cost-effective breakdown which enhances enzymatic accessibility to lignocellulosic materials. Methods and devices shown can be used to produce products such as pulp, chemicals, or biofuels.
