Notario Collado, Belén Pinto Sanz, Javier Verdejo, Raquel Rodríguez Pérez, Miguel Ángel Producción Científica In recent years, there has been a significant interest of the scientific community on nanocellular polymeric foams as a possible next generation of materials with a low dielectric constant for microelectronics applications In this work, the dielectric behavior of microcellular and nanocellular poly (methyl methacrylate) (PMMA) based foams has been characterized, both as a function of frequency and temperature, in order to analyze the effect of reducing the cell size to the nanoscale on the dielectric properties. Experimental results have shown clear differences in the dielectric behavior of the samples with cell sizes in the nanoscale as well as a sharp reduction of the dielectric constant when the porosity increases. 2017-09-24 2017-09-24 2017 info:eu-repo/semantics/article Polymer 107 (2016) 302e305 http://uvadoc.uva.es/handle/10324/25882 eng http://www.sciencedirect.com/science/article/pii/S0032386116310230?via%3Dihub info:eu-repo/semantics/restrictedAccess Elsevier Elsevier
