Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, an absorptive layer or reflective layer is disposed between the alternating transmissive regions and absorptive regions and the light input surface and/or light output surface. In another embodiment, the alternating transmissive regions comprise an absorptive material. The light control film can exhibit low transmission of visible light and high transmission of near infrared light. Also described is a light detection system comprising such light control films and a microstructured film.

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.

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: 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.
