Abstract: Pad conditioning brushes are described. In particular, pad conditioning brushes including a carrier layer and a plurality of abrasive particle-free brush bristles extending from the carrier layer are described. The carrier layer and the plurality of brush bristles form a unitary body. Such brushes may provide excellent performance compared to traditional conditioning disks.

Abstract: A conditioning disk with microfeatures is described. More specifically, a conditioning disk with at least one discrete abrasive element and at least one microfeature. The asymmetry of the at least one microstructure may enable, based on orientation, a wide range of pad polishing parameters, such as surface roughness and pad wear rate.

Abstract: The present disclosure provides laminates, which include adhesive materials and methods that allow for the removal of contaminants, e.g. particulate contaminants, from a substrate surface. In one embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a liquid, adhesive precursor and (iii) a film layer. The liquid, adhesive precursor is disposed between the substrate and the film layer. In another embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a cured adhesive layer and (iii) a film layer. The cured adhesive layer is disposed between the substrate and the film layer. The laminates may be used to remove contaminant from the substrate surface by removal of the film layer and the cured adhesive layer, which entraps the contaminant therein.

Abstract: Methods of embedding particles (e.g., nanoparticles) in a coating, the methods including contacting a first surface of a particle layer with a curable resin, followed by curing the curable resin to form a coating having a first coating surface and an opposing second coating surface, resulting in the particles being concentrated at the first coating surface. Also provided are applications for materials prepared according to the disclosed methods in, for example, hardcoating and nano-replication via reactive ion etching.
