   Sammanfattning : Over the past 20 years’ researchers have tried to utilize the remarkable properties of single-walled carbon nanotubes (SWCNTs) to create new high-tech materials and devices, such as strong light-weight composites, efficient electrical wires and super-fast transistors. But the mass production of these materials and devices are still hampered by the poor uniformity of the produced SWCNTs. LÄS MER

4. 8. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

   Sammanfattning : Carbon-based nanomaterials such as carbon nanotubes (CNTs) and graphene, which possess superior electrical, thermal and mechanical properties, have been proposed as alternative materials for future electronics. The proposed applications span from the device level, replacing silicon-based transistors, with single-walled carbon nanotubes (SWCNTs) or graphene, to packaging level using multi-walled carbon nanotubes (MWCNTs) for interconnects.

   Sammanfattning : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. LÄS MER
