  5. 3. Cellulose–Assisted Dispersion of Carbon Nanotubes : From Colloids to Composites

    Author : Alireza Hajian; Lars Berglund; Milo Shaffer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocelluloses; Carbon nanotubes; Composites; Colloids; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : It is a challenge to disperse nanoparticles to obtain a nanostructured composite. This thesis aims at providing a new route to fabricate carbon nanotube (CNT) composites and suggests mechanisms for nanocellulose–CNT interactions. This route is based on unmodified CNT dispersed in water with the help of nanocellulose. READ MORE

  6. 4. Dispersing Carbon Nanotubes: Towards Molecular Understanding
