1. 1. Chemical Modification of Cellulose Fibres and Fibrils for Design of New Materials

   Författare :Verónica López Durán; Lars Wågberg; Per A. Larsson; Akira Isogai; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; borohydride reduction; cellulose-based materials; chemical modification; chlorite oxidation; fibres; fibrils; periodate oxidation; TEMPO oxidation; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Due to the growing interest in biobased materials in today’s society, where the need for a cyclic economy is obvious, there has been a huge increase in the  interest for using cellulose due to its excellent mechanical and chemical properties. However, the properties of cellulose have to be modified and improved in order to satisfy advanced material applications where the cellulose properties can be tuned to fit the properties of other components in composite mixtures.

7. 5. Nanocellulose Oxidation - Fundamentals and Application in Hydrogels

   Författare :Saül Llacer Navarro; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sulfate half-ester group; cellulose oxidation; polysaccharide hydrogels; Nanocellulose;

   Sammanfattning : The adaptable surface chemistry of cellulose nanocrystals (CNCs) makes them outstanding; it provides colloidal stability, which is essential for engineering use, to commercially-available CNCs. Colloidal stability is achieved by the bulky negatively-charged sulfate half-ester groups on the surface that it manufactures itself via the use of sulfuric acid. LÄS MER
