6. Development of softwood kraft lignin based carbon fibers
Sammanfattning : The polymer composites designed for high-performance applications are mostly based on carbon fiber reinforcement. The two most common precursors used currently for carbon fiber production are poly(acrylonitrile) and pitch (petroleum- or coal- based). As of today, the most promising alternative to these fossil originated raw materials is lignin. LÄS MER
7. Melt Spun Electro-Conductive Polymer Composite Fibers
Sammanfattning : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.

8. Tunable photonic crystals based on carbon nanofibers
Sammanfattning : Photonic crystals are materials with periodically varying refractive indices. In conventional photonic crystal design it is hard to achieve tunable structures in the visible range, i.e. structures with changeable optical properties. LÄS MER
9. LiFePO4-coated carbon fiber electrodes for structural batteries
Sammanfattning : Lithium-ion batteries (LIBs) have a central role in products, from portable devices to large-scale energy storage for the electric grid and continue to undergo rapid development. The surge in electric vehicles has intensified the focus on technological advancements and new-generation technologies. LÄS MER
10. Structural Lithium Ion Battery Electrolytes
Sammanfattning : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. LÄS MER
