We prepared the amine epoxy adducts (AEA)/thin multiwalled carbon nanotubes (TWCNTs) composite particles using nonsolvent
based methods including dry mechano-chemical bonding(MCB) process and supercritical fluid (SCF) process. The
resulting TWCNTs/AEA composite particles have been used as curing agents for urethane modified bispheol A type epoxy
resin. The thermal, thermomechanical properties of the epoxy resins cured with TWCNTs/AEA composite particles were
measured by DMA and the dispersion of CNT was characterized by SEM. Because of high degree of CNT dispersion,
thermal and mechanical properties of the epoxy resin cured with TWCNTs/AEA composite particles prepared by SCF process
are better than those cured with mechano-chemically prepared TWCNTs/AEA composite particles.
