Deposition of SiO2 and TiO2 nanoclusters is performed on non-expanded polystyrene beads using reactive magnetron sputtering technique. This invention covers combined three-step method: change of polystyrene beads surface energy using low-temperature plasma activation (Tions \u2264 105 K) in order to improve nanoclusters adhesion on beads surface; formation of nanoclusters in reactive Ar+O2 gas environment; expansion of polystyrene beads and formation of expanded polystyrene slabs.<\/p>\n<p>Patent number 6383<\/p>\n<p><a href=\"http:\/\/www.vpb.gov.lt\/db_patentai\/rezult-singl.php?id=X531298\">The Patent<\/a><\/p>\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" width=\"1013\" height=\"285\" src=\"http:\/\/www.inovatas.lt\/wp-content\/uploads\/2020\/08\/bubbles.png\" alt=\"\" class=\"wp-image-891\" srcset=\"https:\/\/www.inovatas.lt\/wp-content\/uploads\/2020\/08\/bubbles.png 1013w, https:\/\/www.inovatas.lt\/wp-content\/uploads\/2020\/08\/bubbles-300x84.png 300w, https:\/\/www.inovatas.lt\/wp-content\/uploads\/2020\/08\/bubbles-768x216.png 768w\" sizes=\"(max-width: 1013px) 100vw, 1013px\" \/><figcaption>Graphical abstaract<\/figcaption><\/figure><\/div>\n\n\n\n<p>Varnagiris \u0160., Donelien\u0117 J., Tu\u010dkut\u0117 S., \u010c\u0117snien\u0117 J., Lelis M., Mil\u010dius D.\u00a0Expanded polystyrene foam formed from polystyrene beads coated with a nanocrystalline SiO2 film and the analysis of its moisture adsorption and resistance to mechanical stress \/\/ Polymer-Plastics Technology and Engineering Vol. 57, Iss. 13. 2018. p. 1296-1302<\/p>\n\n\n\n<p>Varnagiris \u0160., Girdzevi\u010dius D., Urbonavi\u010dius M., Mil\u010dius D.\u00a0Incorporation of SiO2 and TiO2 additives into expanded polystyrene foam using physical vapour deposition technique (10.1016\/j.egypro.2017.09.073) \/\/ Energy Procedia.
