2. 1. Tailored layer-by-layer films of nanofibrillated cellulose

   Author : Erdem Karabulut; Lars Wågberg; Lennart Piculell; Eva Blomberg; KTH; []
   Keywords : layer-by-layer assembly; nanofibrillated cellulose; thin film; surface adsorption; polyelectrolytes;

   Abstract : The preparation of multifunctional films, coatings and membranes from natural, sustainable and low-cost raw materials has attracted considerable interest during the last decade. In this respect, cellulose-based products possess a great promise for research and industry due both to the availability of large amounts of material in nature and to the preparation of new classes of nano-sized and well-characterized building-blocks of cellulose from trees or annual plants.

4. 2. Nanofiber networks, aerogels and biocomposites based on nanofibrillated cellulose from wood

   Author : Houssine Sehaqui; Lars A. Berglund; Ton Peijs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibrillated cellulose; nanopaper; nanofiber; biocomposites; aerogel; foam; Materials science; Teknisk materialvetenskap;

   Abstract : Nanofibrillated cellulose (NFC) from wood is an interesting material constituent of high strength and high aspect ratio, which easily forms networks through interfibril secondary bonding including hydrogen bonds. This has been exploited in preparation of new materials, which extend the range of properties for existing cellulosic materials. READ MORE

5. 3. Dried nanofibrillated cellulose and its bionanocomposites

   Author : Christian Eyholzer; Olli Ikkala; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : During the past decade there has been a growing interest in the reinforcement of synthetic polymers with cellulose nanowhiskers and nanofibrillated cellulose (NFC) obtained from plants or bacteria. Their beneficial mechanical properties like high stiffness and strength, in combination with their low mass allowed successful reinforcement of water based polymer dispersions (latexes) for the production of solution cast composite films.

6. 4. Flexible and Cellulose-based Organic Electronics

   Author : Jesper Edberg; Magnus Berggren; Isak Engquist; Leif Nyholm; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

   Abstract : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. READ MORE

7. 5. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

   Author : Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. READ MORE
