Vertically aligned carbon nanotubes (VACNTs) grown on bulk copper substrate are of great importance for real-life commercial applications of carbon nanotubes (CNTs) as thermal interface materials in microelectronic packaging. However, their reproducible syntheses have been a great challenge so far. In this study, by introducing a well-controlled conformal Al2O3 support layer on the bulk copper substrate...
SiC particles and epoxy resin were applied to prepare a potential high thermal conductivity underfill material. SiC particles are thermally coated with a nano layer silica by oxidation at high temperature. Then silane was used as the surface treatment of the silica coated SiC particles to improve the interaction between filler and polymer matrix. TEM and TGA measurements were used to characterize...
Considerable attention has been devoted to the synthesis and application of nanoparticles because of their unusual physical and chemical properties resulted from the ultra-fine size and ultra-large surface area. Polymer composite materials based on metal nanoparticles provide a potential solution to meet the present and future technological demand in virtue of the good processibility and mechanical...
In-situ synthesis of Ag nanoparticles was successfully carried out in various epoxy matrix by photochemical method. The effects of reducing agent type, concentration of metal precursor, epoxy matrix type and additives on the morphology of nanoparticles were explored. Transmission electronic microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the...
Cobalt ferrite nanocomposite was investigated for RF applications. Magnetic nanocomposites were fabricated at different ferritic densities. Cobalt zinc ferrite nanocomposite was also prepared to study the effect of zinc. The size of magnetic nanoparticle was measured by transmission electron microscopy (TEM), while its crystalline structure was characterized by X-ray diffraction (XRD). Toroidal sample...
Tin (Sn) nanoparticles with various sizes were synthesized from a chemical reduction method. Their morphological and thermal characterizations were studied. The high resolution transmission electron microscopy (HRTEM) study showed that significantly low level of oxides was formed. The thermal characterization by differential scanning calorimetry (DSC) exhibited the size dependency of the melting points
Conductive filler-polymer composite materials have been extensively investigated as conductor-insulator percolative system to achieve high dielectric constant (K). Additionally, the effective dielectric constant of conductive filler/polymer composite can be dramatically enhanced by increasing the dielectric constant of polymer matrix according to scaling theory. However, the high dielectric loss of...
