Abstract: A curable composition provides, upon curing, an adhesive made from energy-curable compounds having one set of adhesive properties (i.e., peel, tack and shear) after curing and a second set of adhesive properties after being subjected to some external stimuli, such as heat, light, chemicals or mechanical stresses. The curable composition comprises at least one urethane (meth)acrylate oligomer having a structure comprising: a1) at least one polyol backbone segment having at least one reacted end; a2) at least one reacted polyisocyanate forming a urethane linkage at the at least one reacted end of each of the at least one polyol backbone segment and a3) at least one blocking end group reacted with the at least one reacted polyisocyanate to form a reversible bond and bearing a (meth)acrylate group and a chain terminator or extender.

Abstract: A method of fabricating a polishing layer of a polishing pad includes successively depositing a plurality of layers with a 3D printer, each layer of the plurality of polishing layers deposited by ejecting a base material from a first nozzle and an additive material from a second nozzle and solidifying the base and additive material to form a solidified pad material.

Abstract: A method of fabricating a chemical mechanical polishing pad includes introducing polymer precursors containing acrylate functional groups into a mold, providing abrasive particles and a photo-initiator in the polymer precursors to form a mixture, and while the mixture is contained between a bottom plate and a top cover of the mold, exposing the mixture to ultraviolet radiation through a transparent section of the mold to cause the polymer precursors to form radicals, forming a polymer matrix from the polymer precursor by causing the radicals to cross-link with one another. The polishing layer includes the polymer matrix having the abrasive particles dispersed therein.

Abstract: Embodiments of the present invention relate generally to lithium-ion batteries, and more specifically, to batteries having integrated separators and methods of fabricating such batteries. In one embodiment, a lithium-ion battery having an electrode structure is provided. The lithium-ion battery comprises an anode stack, a cathode stack, and a porous electrospun polymer separator comprising a nano-fiber backbone structure. The anode stack comprises an anodic current collector and an anode structure formed over a first surface of the anodic current collector. The cathode stack comprises a cathodic current collector and a cathode structure formed over a first surface of the cathodic current collector. The porous electrospun polymer separator is positioned between the anode structure and the cathode structure.

Abstract: Highly crystalline metal oxide-carbon composites, as precursors to thermally stable mesoporous metal oxides, are coated with a layer of amorphous carbon. Using a ‘one-pot’ method, highly crystalline metal oxide-carbon composites are converted to thermally stable mesoporous metal oxides, having highly crystalline mesopore walls, without causing the concomitant collapse of the mesostructure. The ‘one-pot’ method uses block copolymers with an sp or sp 2 hybridized carbon containing hydrophobic block as structure directing agents which converts to a sturdy, amorphous carbon material under appropriate heating conditions, providing an in-situ rigid support which maintains the pores of the oxides intact while crystallizing at temperatures as high as 1000 deg C. A highly crystalline metal oxide-carbon composite can be heated to produce a thermally stable mesoporous metal oxide consisting of a single polymorph.
