AB The main aim of this research is to increase the thermal conductivity of flexible PU foams by the addition of single wallcarbon nanotubes (SWCNT). Four techniques to maximise dispersion of nanotube in different mediums before its additionto a flexible Polyurethane (PU) matrix have been used. Semiempirical obtained solid conductivity values for all studiedsamples have been compared with theoretical models (mixing rule and Kapitza models), to assess whether fillerpercolation did take place or not. The effect of dispersion technique and percolation network in cellular structuralchanges has also been analysed. Net obtained thermal conductivity gain, directly attributed to addition of SWCNT is25,6 %, referred to a pure flexible foam.
