Sammanfattning : Conventional polymer composites are highly demanding due to their high strength and stiffness, low weight, easy processing and corrosion resistance. However, their weak out of plane properties restricts their use in high performance applications, such as aerospace, military and automotive components. LÄS MER

Sammanfattning : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

Sammanfattning : Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix. LÄS MER

Sammanfattning : Utilizing density functional theory (DFT) the Vienna Ab initio Simulation Package (VASP) was used to calculate the Raman spectra for five single-walled carbon nanotubes (SWCNTs) with chiralities (4,4), (6,6), (8,0), (12,0) and (7,1). The radial breathing mode (RBM), when compared with experimental frequencies, shows good correlation. LÄS MER
