Abstract: Electronics packaging is fast paced area of research as scientists work to keep up with the new demands of smaller, more powerful electronic devices. In this study, researchers looked at how the manufacturing technique used to create vapour grown carbon nanofiber  (VGCNF)/rubbery epoxy composites affects the thermal conductivity, electrical conductivity and mechanical properties of the final product. Samples were produced by one of three methods: mechanical mixing (MM), three-roll milling (RM), or combined sonication and mechanical mixing (CSM). Thermal conductivity testing was performed with the Hot Disk TPS. Structural investigations revealed that the RM technique was much better at homogenously dispersing the fibers, and did a better job of breaking up agglomerates. The team concluded that the RM method is best for producing this type of polymer.
