    Sammanfattning : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. LÄS MER

  5. 4. Importance of atomic force microscopy settings for measuring the diameter of carbon nanotubes

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Anton Almén; [2019]
    Nyckelord :Carbon nanotubes CNTs ; Atomic force microscopy AFM ; diameter; height; tapping; frequency; phase; amplitude; setpoint; Kolnanorör; Atomkraftsmikroskopi AFM ; diameter; höjd; svängning; frekvens; fas; amplitud; börvärde;

    Sammanfattning : Carbon nanotubes (CNTs) have gathered a lot of interest because of their extraordinary mechanical, electrical and thermal properties and have potential applications in a wide variety of areas such as material-reinforcement and nano-electronics. The properties of nanotubes are dependent on their diameter and methods for determining this using atomic force microscopy (AFM) in tapping mode assume that the measured height of the tubes represent the real diameter.

  7. 5. Reprocessing and Characterisation of High Density Polyethylene Reinforced with Carbon Nanotubes

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

    Författare :Sofie Svensson; [2017]
    Nyckelord :HDPE; mechanical recycling; carbon nanotubes; nanocomposites;

    Sammanfattning : Nanokomposit innehållande högdensitetspolyeten och kolnanorör återvanns och analyseradesför att undersöka hur materialets egenskaper påverkas av återvinning. Kompositenproducerades med 3 viktprocent kolnanorör och återvanns tio gånger genom att extrudera ochmala ner materialet. Analyser gjordes efter varje cykel av extrudering. LÄS MER
