    Abstract: The present disclosure relates to abrasive articles including conformable coatings, e.g. a hydrophobic coating, methods of making and polishing systems therefrom. The present disclosure provides an abrasive layer, having a hydrophobic exterior surface, including at least one of (i) a plurality of individual diamond particles and (ii) a plurality of engineered features having a conformable diamond layer and; a conformable hydrophobic layer in contact with and at least partially coating at least one of the plurality of individual diamond particles and the conformable diamond layer and, wherein the conformable hydrophobic layer includes diamond like glass and forms the hydrophobic exterior surface and the contact angle of the hydrophobic exterior surface is greater than 110 degrees.

    Abstract: Stray light absorbing films are described. In particular, stray light films including a black substrate, and first and second sets of microstructures are described. The described films can reduce stray light reflections in sensor modules and other optical devices. The first set of microstructures can have an average largest diameter between 0.5 and 125 μm. The second set of microstructures can have an average largest diameter of less than ½ of the average largest diameter of the first set of microstructures. The stray light absorbing film can have a specular reflectance for 8° incidence for wavelengths from 350-1200 nm of less than 0.3%.

    Abstract: The disclosure relates to an abrasive article that includes a fabric substrate comprising strands forming first void spaces between the strands. The fabric substrate comprising an abrasive side and an attachment side. The abrasive article also includes a coating on the attachment side. The abrasive article also includes a make layer joined to the fabric substrate on the abrasive side. The abrasive article also includes abrasive particles joined to the make layer. The abrasive article also includes a plurality of second void spaces extending through the make layer coinciding with first void spaces in the fabric substrate. The coating on the fabric substrate is both hydrophobic and lipophobic. The attachment side of the fabric substrate is substantially free of make layer.

    Abstract: The present disclosure provides an article including an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and a ceramic layer disposed on the nanostructured first surface of the organic layer and filling at least a portion of the nanorecesses. The ceramic layer has a nanostructured first surface including nanofeatures and an opposing second surface, and the nanostructured first surface of the ceramic layer is interpenetrated with the nanostructured first surface of the organic layer. The present disclosure also provides a method of making the article. The method includes obtaining an organic layer having a nanostructured first surface including nanofeatures defining nanorecesses and an opposing second surface; and filling at least a portion of the nanorecesses of the nanostructured first surface of the organic layer with a ceramic material to form the article. In addition, the present disclosure provides articles including interpenetrating layers having different elastic storage moduli, such as non-metallic layers, and methods of making the articles. The articles can exhibit high abrasion resistance.
