1. 1. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

   Författare :Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

   Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.
