Tunable High Refractive Index Polymer Hybrid and Polymer–Inorganic Nanocomposite Coatings

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 1.936 at 635 nm wavelength have been obtained ASPD 4-bromostyrene/toluene–TiO2 layers containing low titania loadings. Thin films with any desired up to can be easily deposited onto variety substrates by varying precursor mixture composition. overcomes disadvantages commonly associated alternative fabrication methods depositing coatings (elevated temperatures, wet processes, UV curing steps, much greater inorganic loadings).
