Multi-walled carbon nanotube/epoxy resin (MWCNT/EP) composites with filler contents from 0.03wt% to 0.5wt.% and two different aspect ratios are prepared by solution blended process. Carbon nanotubes are dispersed by sonication and high speed shear force. The impact of aspect ratio on electric and thermal conductivity of nanocomposites has been studied. Experiment results illustrate that percolation...
Thermal management is one of the critical challenges in three-dimensional (3D) integration. This paper reports an approach to increasing the thermal conductivity of the bonding adhesive Benzocyclobutene (BCB) by loading carbon nanotubes (CNTs). By exploiting the aromatic property of BCB, an ultrasonication and mechanical stirring assisted non-covalent dispersion method is developed to disseminate...
We describe (i) the evaluation of bundled degrees of single-walled carbon nanotubes (SWNTs) in SWNT/UV-curable resin composite films based on the intensity change in the radial breading mode (RBM) of their Raman spectra at a 785-nm excitation, and (ii) the thermal conductivity measurements of the composites films using the temperature wave analysis method. The homogeneous dispersion of the SWNTs produced...
Carbon nanotube enhanced thermally conductive phase change material for heat dissipation has been studied in the present paper. It was indicated that the thermal resistance was greatly reduced by incorporating multi-walled carbon nanotubes into the organic matrix. The uniform distribution of carbon nanotubes has been realized by optimizing the dispersion parameters like temperature, shear strength,...
