Atomized spray plasma deposition (ASPD) provides a single-step, low-temperature, and dry approach for the preparation of high refractive index hybrid polymer or polymer–inorganic nanocomposite coatings. Refractive indices as high as 1.936 at 635 nm wavelength have been obtained for ASPD 4-bromostyrene/toluene–TiO 2 nanocomposite layers containing low titania loadings. Thin films with any desired refractive index up to 1.936 can be easily deposited onto a variety of substrates by varying the precursor mixture composition. ASPD overcomes disadvantages commonly associated with alternative fabrication methods for depositing high refractive index coatings (elevated temperatures, wet processes, UV curing steps, and much greater inorganic loadings).

The practical viability of these low loading (sub 0.1 mol%) palladium catalyst membranes for continuous flow reactions at ambient temperature is demonstrated for the Suzuki-Miyaura carbon-carbon coupling reaction by contacting the reactant mixture with the catalyst membrane and applying sonication. The Suzuki-Miyaura carbon-carbon coupling reaction proceeds at the palladium-poly(ionic liquid) catalyst membrane surface in conjunction with selective permeation (separation) of the desired product species through the underlying porous support. These palladium-poly(ionic liquid) catalyst membranes display minimal metal leaching enabling them to be reused multiple times.
