  1. 1. Nanolatexes: a versatile toolbox for cellulose modification

    Författare :Alexandros Efraim Alexakis; Eva Malmström; Justin Zoppe; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanolatexes; RAFT; PISA; adsorption; cellulose; modification; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. LÄS MER
