  1. 1. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Author : Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. READ MORE

  2. 2. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface

    Author : Mohd Farhan Ansari; Lars Berglund; Jean-Francois Gerard; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Wood; cellulose nanofibrils; hygromechanical properties; network structure; thermoset; polymer matrix composites; natural fiber composites; pulp fiber; strain hardening; humidity; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.

  3. 3. Properties and performance of regenerated cellulose thermoset biocomposites

    Author : Sunil Kumar Ramamoorthy; Jyrki Vuorinen; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; regenerated cellulose fibres; surface modification; alkali; silane; mechanical analysis; biocomposites; renewable resources; Resursåtervinning; Resource Recovery;

    Abstract : Biocomposites have been developed to address the sustainability issues of nonrenewableresource based materials. These composites are often produced by reinforcing natural fibres in petroleum based thermoset resins or thermoplastic polymers. READ MORE

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

    Author : Houssine Sehaqui; Lars A. Berglund; Ton Peijs; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. 5. Tuning the long-term properties to control biodegradation by surface modifications of agricultural fibres in biocomposites

    Author : Thorsak Kittikorn; Monica Ek; Ferruccio Doghieri; KTH; []
    Keywords : agricultural fibres; biocomposites; renewable polymers; PP; PLA; PHBV; surface modifications; water uptake; microbial growth; biodegradation;

    Abstract : Sustainable polymeric materials put emphasis on mastering the whole life-cycle of polymeric materials. This includes the choice of raw materials, selection of synthesis and processing, environmental impact during long-term use followed by detailed knowledge about recycling and waste management.
