Abstract

Hyperbranched poly(urea-urethane)-grafted multi-walled carbon nanotubes (HPU-MWCNTs) were incorporated in a polyurethane (PU) matrix based on poly(ethylene oxide-tetrahydrofuran) and aliphatic polyisocyanate resin as curing agent. The 9-12 nm thick HPU shell formed on the MWCNTs improved the dispersion of MWCNTs and enhanced the interfacial adhesion between the PU matrix and MWCNTs, leading to improvements in storage modulus and T _g of the composites and enhancement of the thermal stability of PU. Thus, composites with 0.5-1 wt% MWCNTs increased the thermal conductivity by about 60-70% when compared to, and retained the high electrical resistivity of, neat PU.
