Problems solved by technology

However, the hybrid anti-reflective, anti-glare surface has a structural scale close to the wavelengths of the visible spectrum, and thus can cause high haze (ie >4%), reducing display quality

[0270] Process 1: Vacuum plasma treatment plasma heating batch reactor

[0271] A batch plasma system (available from Oerlikon, St. Petersburg, FL under the trade designation "PLASMATHERM" (model 3032)) configured for reactive ion etching (RIE) with 68.6 cm (27 in.) low-level power electrodes and central air pump. The chamber was pumped by a dry mechanical pump (available as model iQDP80 from Edwards Vacuum) via a Roots blower (available as model EH1200 from Edwards Vacuum, Tewsbury, MA). Do the pumping. RF power was provided by a 3 kW, 13.56 Mhz solid-state generator (commercially available under the trade designation "RFPP" (model RF30H) from Advanced Energy, Fort Collins, CO) through an impedance-matched network. The system has a nominal base pressure of 5 mTorr. The flow rate of the gas was controlled by a flow rate controller (commercially available from MKS Instruments, Woburn, MA) under the trade designation "MKS 1179".

[0303] 450 g of 1-methoxy-2-propanol, 6 g of 3-(methacryloxy)propyltrimethoxysilane, and 0.16 g of a 5% aqueous solution of hindered amine nitroxide inhibitor (“PROSTAB5128”) Mix together with 190nm silica dispersion ("MP2040") while stirring. The solution was sealed in a jar and heated to 80°C and held at that temperature for 16 hours. Water and 1-methoxy-2-propanol were removed from the mixture by rotary evaporation. The resulting dry, surface-functionalized silica particles were redispersed into an 88 / 12 1-methoxy-2-propanol / water mixture, then sonicated and filtered to form a 42.4% by weight solid dispersion.

[0304] A monomer blend of pentaerythritol triacrylate, 1,6-hexanediol diacrylate and isobornyl acrylate ("SR444", "SR238", "SR506", respectively) was mixed in a 40 / 40 / 20 ratio with Dispersions of 190 nm silica particles modified with 3-(methacryloxy)propyltrimethoxysilane were blended to form 65% by weight of 3-(methacryloxy)propyltrimethoxysilane Oxysilane-modif...

Abstract

Material comprising sub-micrometer particles dispersed in a polymeric matrix. The materials are useful in article, for example, for numerous applications including display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and construction applications or traffic signs.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of the following patent applications: Provisional Patent Application Nos. 61 / 524,406, filed August 17, 2011, and 61 / 593,696, filed February 1, 2012, the disclosures of which are incorporated by reference in their entirety into this article. Background technique [0003] As light travels from one medium to another, some portion of the light is reflected from the interface between the two media. For example, typically about 4-5% of light impinging on a transparent plastic substrate is reflected at the top surface. [0004] Backlighting for mobile handsets and laptops cannot effectively provide the required display quality in the presence of reflections of external lighting from the top surface of the display device and internal interfaces Interfering images degrade viewing quality. [0005] Different approaches have been taken to reduce reflections from the top surface of a display d...
