  1. 1. Development of a porous material from cellulose nanofibrils

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Hedda Törneman; [2021]
    Nyckelord :CNF; cellulose nanofibrils; xerogels; aerogels; cross-linking; porous materials; polymers;

    Sammanfattning : Cellulose nanofibrils are a biobased and renewable material with potential to be used in many different applications. Such applications include air filtration, absorption of liquids, and thermal insulation.  To be used for these applications the cellulose nanofibrils must form a porous and dry material. LÄS MER

  5. 4. Dewatering Cellulose Nanofibril Suspensions through Centrifugation

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jennifer Astorsdotter; [2017]
    Nyckelord :Cellulose nanofibrils; Microfibrilated cellulose; Centrifugation; Dewatering; Fiber suspension; Cellulosa nanofibriller; CNF; Microfibrilerad cellulosa; MFC; Centrifugering; Avvattning; Fibersuspension.;

    Sammanfattning : Cellulose nanofibrils (CNF) is a renewable material with unique strength properties. A difficulty in CNF production is that CNF suspensions contain large amounts of water. If CNF suspension volume can be decreased by dewatering facilitated by centrifugation, then transportation costs and storage costs can be reduced. LÄS MER
