Abstract: Asymmetric films, methods of making asymmetric films, and uses of asymmetric films. A method may include using at least two different solvents and at least one homopolymer and at least one block copolymer that can undergo self assembly, where the solvents are immiscible and have different surface tension, where, on film formation, all or substantially all of the block copolymer(s) migrate to an exterior surface of the homopolymer. The asymmetric films may include an isoporous region or layer and an asymmetric region or layer, where the asymmetric region does not include 10 percent by weight or more of the multiblock copolymer(s) and/or the isoporous region/layer and the asymmetric pore region/layer are not independently (or separately) formed and/or not laminated together to form the asymmetric film. The films can be used in devices, such as, for example, filtration devices.

Abstract: A method of forming a CMP pad includes providing a solution of a block copolymer (BCP), where the BCP includes a first segment and a second segment connected to the first segment, the second segment being different from the first segment in composition. The method further includes processing the BCP to form a polymer network having a first phase and a second phase embedded in the first phase, where the first phase includes the first segment and the second phase includes the second segment, and subsequently removing the second phase from the polymer network, thereby forming a polymer film that includes a network of pores embedded in the first phase. Thereafter, the method proceeds to combining the CMP top pad and a CMP sub-pad to form a CMP pad, where the CMP top pad is configured to engage with a workpiece during a CMP process.
