Abstract

In this work, we have synthesized Titanate nanotube(TiNT) and Layered Double Hydroxide(LDH) nanoparticles and studied about their applicable properties as inorganic filler due to their high porous structure, and then the obtained nanoparticles were dispersed in exfoliated vermiculites, in order to apply this technology to the fabrication process of vermiculite-TiNT/LDH filler composites for heat inulating materials. The changes in thermal conductivity of heat insulating composites was compared according to the type and amount of inorganic filler. The thermal conductivities were confirmed to be reduced in proportion with the amount of inorganic nanofillers, which led to more effective heat insulating properties. Especially, the trends were observed more obviouly in TiNT with more porous structure.
