    Light weight, highly conductive (both electrically and thermally) multiwalled carbon nanotube (MWNTs) sheets can be used as an effective electric heating element. In this paper, silver nanoparticles were anchored onto carboxyl functionalized multiwalled carbon nanotubes (MWNTs) by photochemical reaction to enhance the transport properties of the resultant nanohybrid sheet. The nanohybrid sheet was then integrated into the Kevlar/epoxy sandwich structure by resin infusion method. When conducting a current through an area of 24.6×20.7mm, the sample temperature reached the steady-state value (e.g. 110oC) within 13s by consuming a power density of 0.58W/in2. In addition, the laminate structure showed a stable reversibility after a number of heating cycles, which indicated it’s potential for thermal interface materials, sensors and de-icing applications.
