    Abstract: Article (9,19) comprising a substrate (10, 20) comprising a polymer and having first (11,21) and second (12, 22) opposed major surfaces. The first major surface (11, 21) has first surface regions (13, 23) with first nanoparticles (14a, 14b, 14c, 14d, 24a, 24b, 24c, 24d) partially embedded into the first major surface (11, 21), and one of • (a) second surface regions (15) free of nanoparticles; or • (b) second surface regions (25) with at least second nanoparticles (28) on the first major surface (11, 21) or partially embedded into the first major surface (11, 21). The first surface regions (13, 23) have a first average surface roughness, R a1 , of at least 20 nm, wherein the second surface regions (15, 25) have a second average surface roughness, R a2 , of less than 100 nm, wherein the first average surface roughness, R a1 , is greater than the second average surface roughness, R a2 , and wherein there is an absolute difference between the first and second average surface roughness of at least 10 nm.

    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: The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes a) 40-60 parts by weight of a monofunctional (meth)acrylate monomer, per 100 parts of the total photopolymerizable composition; b) a photoinitiator; and c) a polymerization reaction product of components. A cured homopolymer of the monofunctional (meth)acrylate monomer has a glass transition temperature of 125 degrees Celsius or greater. The polymerization reaction product of components includes i) a diisocyanate; ii) a hydroxy functional methacrylate; iii) a polycarbonate diol; and iv) a catalyst. The polymerization reaction product includes a polyurethane methacrylate polymer. Often, the polycarbonate diol has a number average molecular weight of greater than 1,000 grams per mole (g/mol) or a weighted average of all polycarbonate diols present in the components has a Mn of greater than 1,000 g/mol; alternatively, the polyurethane methacrylate polymer has a weight average molecular weight of 8,000 g/mol or greater. An article is also provided including the photopolymerizable composition reaction product. Further, the present disclosure provides articles and methods of making articles. Methods are additionally provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.
