Carbon Nanotube Microarchitectures for Enhanced Thermal Conduction at Ultralow Mass Fraction in Polymer Composites

Abstract

A carbon-nanotube architecture based on ceramic microparticles allows for strikingly reducing the number of thermal contact resistances between carbon nanotubes (CNT). The result is a 130% enhancement of the thermal conductivity of the nanocomposites at a remarkably low CNT mass fraction of 0.15 wt%.
