The microwave drying is an alternative ambient pressure drying technique for these nanostructured materials that allows a fast fine drying stage and avoids the high temperature cycles of conventional evaporative drying. The gels were synthesized by a two\u2010step acid\u2010base catalyzed sol\u2010gel process following the procedures described in an earlier work. After 2 days of aging, they were placed in an oven at 60\u00b0C, during one day, and then washed with distilled water at 40\u00b0C. Finally, the gels were dried in a microwave oven, at 450 W, in three cycles of two minutes each with two minutes of interval. During drying, a reduction of the gel volume was observed, but the major part of this volume was recovered by spring\u2010back effect in 2 days, giving aerogel\u2010like materials with a density in the interval 60\u201380 kg\/m<jats:sup>3<\/jats:sup>. The final materials are monolithic, flexible and have a thermal conductivity of \u02dc0.04 W\/(m K), which make them suitable for insulation applications. Additionally, they exhibit high hydrophobicity (contact angle \u02dc150\u00b0) and surface area (414 m<jats:sup>2<\/jats:sup>\/g), what can be beneficial for adsorption of some organic pollutants.<\/jats:p>","DOI":"10.1002\/mawe.201300140","type":"journal-article","created":{"date-parts":[[2013,5,29]],"date-time":"2013-05-29T12:04:42Z","timestamp":1369829082000},"page":"380-385","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Silica based aerogel\u2010like materials obtained by quick microwave drying"],"prefix":"10.1002","volume":"44","author":[{"given":"L.","family":"Dur\u00e3es","sequence":"first","affiliation":[]},{"given":"T.","family":"Matias","sequence":"additional","affiliation":[]},{"given":"R.","family":"Patr\u00edcio","sequence":"additional","affiliation":[]},{"given":"A.","family":"Portugal","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2013,5,29]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1166\/jnn.2012.4560"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcis.2006.03.044"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.micromeso.2006.10.026"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/AST.63.41"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10971-011-2604-7"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcis.2012.04.062"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr0101306"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2007.10.060"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1590\/S1516-14392002000400009"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1009625914689"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.molstruc.2008.08.025"},{"key":"e_1_2_1_13_2","unstructured":"H.
