2. 6. ARGET ATRP as a Tool for Cellulose Modification

   Author : Susanne Hansson; Eva Malmström; Anna Carlmark; Steve Edmondson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The importance of finding new applications for cellulose‐based products has increased, especially to meet the demand for new environmentally friendly materials, but also since the digitalization of our society will eventually decrease the need for paper. To expand the application area of cellulose, modification to improve and/or introduce new properties can be a requisite. READ MORE
