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, Ra1, of at least 20 nm, wherein the second surface regions (15, 25) have a second average surface roughness, Ra2, of less than 100 nm, wherein the first average surface roughness, Ra1, is greater than the second average surface roughness, Ra2, and wherein there is an absolute difference between the first and second average surface roughness of at least 10 nm.

Abstract: Provided are acoustic articles having a porous layer (102,104,106) placed in contact with a heterogeneous filler comprising porous carbon and having an average surface area of from 0.1 m2/g to 10,000 m2/g. The acoustic articles can have a flow resistance of from 10 MKS Rayls to 5000 MKS Rayls. Optionally, the porous layer includes a non-woven fibrous layer or a perforated film having a plurality of apertures with an average narrowest diameter of from 30 micrometers to 5000 micrometers. The heterogeneous filler can enhance low frequency performance without significantly compromising high frequency performance, thickness or weight.

Abstract: A method comprises exposing a particle coating disposed on a nonwoven fiber web comprising thermally-softenable fibers to pulsed electromagnetic radiation having at least one wavelength in the range of 200 nm to 1000 nm. The particle coating comprises distinct particles that are not chemically bonded to each other, and are not retained in a binder material other than the thermally-softenable fibers. Also disclosed are nonwoven articles comprising a thermally-softenable nonwoven fiber web having a particle coating disposed thereon. The particle coating comprises distinct particles that are not chemically bonded to each other and are not retained in a binder material other than the thermally-softenable nonwoven fiber web. The particle coating is at least 60 percent retained after a one minute immersion in isopropanol at 22° C.
