  1. 1. Tribological Performance of Polymer Based Self-lubricating Coatings

    Master-uppsats, Luleå tekniska universitet/Maskinelement

    Författare :Amit Roy; [2019]
    Nyckelord :polyimide coatings; carbon nanotube; graphene; tribological properties; elevated temperature.;

    Sammanfattning : The thesis comprises the two parts in each chapter: the first part focuses on the development and characterization of polyimide (PI) based composite coatings on a steel substrate. In order to improve the tribological performance of polyimide coatings, the fillers i.e. LÄS MER

  2. 2. Multiscale Analysis of Multifunctional Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ammara Dil; [2019]
    Nyckelord :;

    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

  3. 3. Thermoset biopolymer reinforced with carbon-nanotubes

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Morteza Esmaeili; [2019]
    Nyckelord :biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

    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.

  4. 4. Patterned Nanocomposite of Carbon Nanotube/Polymer

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Saeed Motaragheb Jafarpour; [2017]
    Nyckelord :;

    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

  5. 5. Carbon Nanotube Raman Spectra Calculations using Density Functional Theory

    L3-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik; Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan Jirlén; Emil Kauppi; [2017]
    Nyckelord :Density Functional Theory; DFT; Single-Walled Carbon Nanotubes; SWCNTs; Raman; Spectra; VASP;

    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
