We obtained good dispersion of the nanoparticles in a mixed solvent of 48% 1-methoxy-2-propanol (MP), 32% 3-methoxy-3-methyl-1-butanol (MMB), and 20% methyl i-butyl ketone (MIBK). An ink of the polymer coating consisting of 68.7 wt% nanoparticles and 31.3 wt% DPHA with a polymerization initiator was prepared using this solvent mixture. The surface of the hybrid film showed low roughness and the nanoparticles formed a densely packed structure in the DPHA matrix. The resulting coating possessed excellent transparency and a high refractive index of 1.69.<\/jats:p>","DOI":"10.3390\/ma10070710","type":"journal-article","created":{"date-parts":[[2017,6,28]],"date-time":"2017-06-28T10:25:56Z","timestamp":1498645556000},"page":"710","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Effect of Core-shell Ceria\/Poly(Vinylpyrrolidone) (PVP) Nanoparticles Incorporated in Polymer Films and Their Optical Properties (2): Increasing the Refractive Index"],"prefix":"10.3390","volume":"10","author":[{"given":"Toshio","family":"Itoh","sequence":"first","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST), Shimo-shidami, Moriyama-ku, Nagoya 463-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshio","family":"Uchida","sequence":"additional","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST), Shimo-shidami, Moriyama-ku, Nagoya 463-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriya","family":"Izu","sequence":"additional","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST), Shimo-shidami, Moriyama-ku, Nagoya 463-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woosuck","family":"Shin","sequence":"additional","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST), Shimo-shidami, Moriyama-ku, Nagoya 463-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S498","DOI":"10.1016\/j.surfcoat.2011.01.010","article-title":"Thin film growth on nanostructured polymer webs for anti-reflection purposes","volume":"205","author":"Munzert","year":"2011","journal-title":"Surf.
