Measurements of the thermal conductivity \u03bb of the air-filled and evacuated PS foams, the influence of temperature T, opacifiers as well as gas pressure p on the thermal conductivity \u03bb are presented. First results of the foam microstructures, as visualized by electron microscopy, confirm that pore sizes below 1\u2009\u00b5m can be achieved. Thermal conductivity values of advanced samples in vacuum of about 7\u2009mW\/(m\u00b7K) were measured. <\/jats:p>","DOI":"10.1177\/0021955x20943101","type":"journal-article","created":{"date-parts":[[2020,10,7]],"date-time":"2020-10-07T06:17:34Z","timestamp":1602051454000},"page":"493-515","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Thermal conductivity analysis of a new sub-micron sized polystyrene foam"],"prefix":"10.1177","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3489-4711","authenticated-orcid":false,"given":"FA","family":"Almeida","sequence":"first","affiliation":[{"name":"va-Q-tec AG, W\u00fcrzburg, Germany"}]},{"given":"H","family":"Beyrichen","sequence":"additional","affiliation":[{"name":"va-Q-tec AG, W\u00fcrzburg, Germany"}]},{"given":"N","family":"Dodamani","sequence":"additional","affiliation":[{"name":"va-Q-tec AG, W\u00fcrzburg, Germany"}]},{"given":"R","family":"Caps","sequence":"additional","affiliation":[]},{"given":"A","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"SUMTEQ GmbH, D\u00fcren, Germany"}]},{"given":"R","family":"Oberhoffer","sequence":"additional","affiliation":[{"name":"SUMTEQ GmbH, D\u00fcren, Germany"}]}],"member":"179","published-online":{"date-parts":[[2020,10,6]]},"reference":[{"key":"bibr1-0021955X20943101","volume-title":"A Roadmap for moving to a competitive low carbon economy in 2050","author":"COM","year":"2011"},{"key":"bibr2-0021955X20943101","volume-title":"Paving the way for effective implementation of policy requirements","author":"Boermans T","year":"2011"},{"key":"bibr3-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2005.06.015"},{"key":"bibr4-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.eurpolymj.2017.08.025"},{"key":"bibr5-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.eurpolymj.2015.11.001"},{"key":"bibr6-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1177\/0021955X08090420"},{"key":"bibr7-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.carbon.2015.06.003"},{"key":"bibr8-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1039\/C7NR00327G"},{"key":"bibr9-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1039\/C8NR90192A"},{"key":"bibr10-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.carbon.2017.05.029"},{"key":"bibr11-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.eurpolymj.2017.11.001"},{"key":"bibr12-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmatsci.2016.02.002"},{"key":"bibr13-0021955X20943101","doi-asserted-by":"publisher","DOI":"10.1007\/s10765-006-0106-6"},{"key":"bibr14-0021955X20943101","unstructured":"SUMFOAM \u2013 Technical information, http:\/\/sumteq.de\/en\/sumfoam\/ (acessed 17 January 2019)."},{"key":"bibr15-0021955X20943101","unstructured":"Strey R, Oberhoffer R, M\u00fcller A.
