The method is based on a sandwich structure consisting of a 4 \u03bcm thick PVA sacrificial layer, the Au-nanorod\/UDMA-TEGDMA nanocomposite layer, and glycerol, all spin-coated sequentially onto a glass slide. Glycerol serves as a cover layer to shut out oxygen during photopolymerization, while the water-soluble PVA enables the subsequent detachment of the nanocomposite film by simple immersion into a liquid bath. Layer thicknesses were controlled by profilometry, while the presence of homogeneously dispersed gold nanorods was confirmed by optical spectroscopy and dark-field optical microscopy. A total of five similar spin-coating scenarios were tested, out of which two approaches produced positive results, with final nanocomposite layer thicknesses in the 2.5\u20134 \u03bcm range, which is smaller than the usual thickness of the oxygen inhibition layer (OIL) commonly present in these types of resins. Optimization of these technological processes and parameters to control film thickness and consistency is discussed in detail.<\/jats:p>","DOI":"10.3390\/polym17101391","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T03:51:03Z","timestamp":1747626663000},"page":"1391","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preparation of Few-Micron-Thick Free-Standing Au-Nanorod\/UDMA-TEGDMA Nanocomposite Films by Using PVA Sacrificial Layers"],"prefix":"10.3390","volume":"17","author":[{"given":"N\u00f3ra","family":"Tarpataki","sequence":"first","affiliation":[{"name":"Department of Electronics Technology, Faculty of Electrical Engineering and Informatics, Budapest University of Technology and Economics, H1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Kecz\u00e1nn\u00e9-\u00dcveges","sequence":"additional","affiliation":[{"name":"Department of Biomaterials and Prosthetic Dentistry, Faculty of Dentistry, University of Debrecen, H4032 Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7052-0322","authenticated-orcid":false,"given":"Melinda","family":"Szal\u00f3ki","sequence":"additional","affiliation":[{"name":"Department of Biomaterials and Prosthetic Dentistry, Faculty of Dentistry, University of Debrecen, H4032 Debrecen, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attila","family":"Bony\u00e1r","sequence":"additional","affiliation":[{"name":"Department of Electronics Technology, Faculty of Electrical Engineering and Informatics, Budapest University of Technology and Economics, H1111 Budapest, Hungary"},{"name":"HUN-REN Wigner Research Centre for Physics, H1525 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12702","DOI":"10.1021\/acs.langmuir.2c02206","article-title":"New Insights into Spin Coating of Polymer Thin Films in Both Wetting and Nonwetting Regimes","volume":"38","author":"Jiang","year":"2022","journal-title":"Langmuir"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1016\/j.eng.2022.07.022","article-title":"Mixed-Matrix Membranes Containing Porous Materials for Gas Separation: From Metal\u2013Organic Frameworks to Discrete Molecular Cages","volume":"23","author":"Yang","year":"2023","journal-title":"Engineering"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Riva, Y.R., and Rahman, S.F.
