However, the low solubility and fast diffusivity of CO2 in PS hinder its potential applications. In this study, an attapulgite (ATP)\/polypyrrole (PPy) nanocomposite was developed using the in situ polymerization method to generate the hierarchical cell texture for the PS foam based on the supercritical CO2 foaming. The results demonstrated that the nanocomposite could act as an efficient CO2 capturer enabling the random release of it during the foaming process. In contrast to the pure PS foam, the ATP\/PPy nanocomposite reinforced PS foam is endowed with high cell density (up to 1.9 \u00d7 106) and similar thermal conductivity as the neat PS foam, as well as high compression modulus. Therefore, the in situ polymerized ATP\/PPy nanocomposite makes supercritical CO2 foaming desired candidate to replace the widely used fluorocarbons and chlorofluorocarbons as PS blowing agents.<\/jats:p>","DOI":"10.3390\/polym11060985","type":"journal-article","created":{"date-parts":[[2019,6,4]],"date-time":"2019-06-04T04:26:40Z","timestamp":1559622400000},"page":"985","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["High Performance Attapulgite\/Polypyrrole Nanocomposite Reinforced Polystyrene (PS) Foam Based on Supercritical CO2 Foaming"],"prefix":"10.3390","volume":"11","author":[{"given":"Yidong","family":"Liu","sequence":"first","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"},{"name":"Dongguan South China Design Innovation Institute, Dongguan 523808, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingfeng","family":"Jian","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianhua","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongtao","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun","family":"Yi","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingzhi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6003-2846","authenticated-orcid":false,"given":"Ruibin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonggang","family":"Min","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Center of Emerging Material and Technology, Guangdong University of Technology, Guangzhou 510006, Guangdong, China"},{"name":"Dongguan South China Design Innovation Institute, Dongguan 523808, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,6,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9145","DOI":"10.1021\/ie4011222","article-title":"Effects of Acidic Sites in HA Zeolite on the fire performance of polystyrene composite","volume":"52","author":"Dong","year":"2013","journal-title":"Ind.
