Under convenient sonomechanical treatment, clay\u2013GNP mixtures may produce very stable water dispersions in particular using sepiolite fibrous clay. While in the absence of clay a rapid decantation of GNP in water is observed, in the presence of sepiolite the resulting dispersions remain stable during months without syneresis effects. Rigid but flexible self\u2010supported films are easily obtained by filtering of these dispersions. As the electrical percolation threshold corresponds to sepiolite\/GNP composites of 0.5:1 in weight, doping these systems with multiwalled carbon nanotubes (MWCNTs) significantly enhances their electrical conductivity. The particular microporosity of the sepiolite component allows interactions with molecules, such as organic dyes, as well as polymers, such as biopolymers, opening the way to functional materials for advanced applications due to their inherent conductivity afforded by the GNP and MWCNTs carbonaceous components. In fact, using very small amount of MWCNT together with GNP can obtain composites with significant electrical conductivity, maintaining the enhanced mechanical properties, at a lower cost.<\/jats:p>","DOI":"10.1002\/adfm.201603103","type":"journal-article","created":{"date-parts":[[2016,8,29]],"date-time":"2016-08-29T03:10:09Z","timestamp":1472440209000},"page":"7394-7405","source":"Crossref","is-referenced-by-count":81,"title":["Clay\u2010Graphene
