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

Ritchie, Angus W. and Cox, Harrison J. and Gonabadi, Hassan I. and Bull, Steve J. and Badyal, Jas Pal S. (2021) 'Tunable High Refractive Index Polymer Hybrid and Polymer–Inorganic Nanocomposite Coatings.', ACS Applied Materials & Interfaces, 13 (28). pp. 33477-33484.


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–TiO2 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).
