  1. 6. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Beyar Abdulla; [2020]
    Nyckelord :Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Sammanfattning : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. LÄS MER

  2. 7. 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.

  3. 8. Mechanical and Thermal Characterisation of Novel UHMWPE Composites for Total Joint Arthroplasty

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

    Författare :Julian Somberg; [2019]
    Nyckelord :UHMWPE; Nanocomposites; DSC; Fracture Toughness; Wear;

    Sammanfattning : Total joint arthroplasty surgeries are known to have a high success rate but the longevity of the implants still acts as a limiting factor. Ultrahigh molecular weight polyethylene is the material of choice for the implant bearing surfaces due to its excellent clinical and tribological performance. LÄS MER

  4. 9. Thermomechanical characterisation of newly developed UHMWPE composites

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

    Författare :Petra Jan; [2019]
    Nyckelord :UHMWPE; nanocomposites; thermomechanical characterisation;

    Sammanfattning : Ultra high molecular weight polyethylene (UHMWPE) is a polymer commonly used in various applications, particularly in hip joint replacements. Despite its good performance, it is susceptible to oxidation degradation, which can be mitigated with the addition of vitamin E, and to excessive wear against metal countersurfaces, which can potentially be improved with the addition of nanoparticles.

  5. 10. Nanomechanical properties of nanocomposite polymer layer

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tomasz Tokarski; [2019]
    Nyckelord :Nanocomposite; nanowear; nano mechanical properties; gel trapping; atomic force microscopy;

    Sammanfattning : Interphase phenomenon gains more and more interest throughout the research community. An interphase is formed between a filler particle and a polymeric matrix, and it may constitute almost the entire volume of a nanocomposite. If the interphase have favorable mechanical properties it will thus result in a nanocomposite with such properties. LÄS MER
