Carbon nanomaterials such as carbon nanotube(CNT) and graphenehave been received much
attention as new materials to overcome the limitation of traditional fillersin nanocompositesdue to
their excellent mechanical, thermal, electrical and chemical properties.The important issues of
carbon nanomaterials fillednanocomposites, regarding their synthesis process, are homogeneous
dispersion of carbon nanomaterialsin matrices and control of interfacial characteristics between
fillers and matrices.The technological issues on the fabrication processes and properties of carbon
nanomaterialsfilled nanocomposites are reviewed. Various types of CNT and graphenefilled
nanocompositesare fabricated and their mechanical andelectricalproperties are characterized. The
carbon nanomaterialsfilled nanocompositesare emerging advanced materials to be applied in
variousstructural and functional application areas such as supercapacitors, Li-ion battery electrodes,
stretchable conductors, solar cells and field emitters.
