Enzymatic hydrolysis combined with mechanical shearing and high-pressure homogenization for nanoscale cellulose fibrils and strong gels.
Marjo Pääkkö,Mikael Ankerfors,Harri Kosonen,Antti Nykänen,Susanna Ahola,Monika Österberg,Janne Ruokolainen,Janne Laine,Per Tomas Larsson,Olli Ikkala,Tom Lindström +10 more
TL;DR: Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.
Journal ArticleDOI
Switching Supramolecular Polymeric Materials with Multiple Length Scales
Janne Ruokolainen,R. Mäkinen,Mika Torkkeli,Tapio Mäkelä,Ritva Serimaa,G. ten Brinke,Olli Ikkala +6 more
TL;DR: It was demonstrated that polymeric supramolecular nanostructures with several length scales allow straightforward tailoring of hierarchical order-disorder and order-order transitions and the concurrent switching of functional properties.
Journal ArticleDOI
Large-area, lightweight and thick biomimetic composites with superior material properties via fast, economic, and green pathways.
Andreas Walther,Ingela Bjurhager,Jani-Markus Malho,Jaakko Pere,Janne Ruokolainen,Lars Berglund,Olli Ikkala +6 more
TL;DR: A surprisingly simple and rapid methodology for large-area, lightweight, and thick nacre-mimetic films and laminates with superior material properties and is ready for scale-up via continuous roll-to-roll processes.
Journal ArticleDOI
Strong Nanocomposite Reinforcement Effects in Polyurethane Elastomer with Low Volume Fraction of Cellulose Nanocrystals
TL;DR: Polyurethane/cellulose nanocrystal nanocomposites with ultra-high tensile strength and stain-to-failure with strongly improved modulus were prepared by adding cellulose Nanocrystals (CNCs) during th...
Journal ArticleDOI
Effect of microfibrillated cellulose and fines on the drainage of kraft pulp suspension and paper strength
TL;DR: In this paper, different types of microfibrillated cellulose (MFC) and fines suspensions were produced, characterized, and then added to a paper-making pulp suspension, and the effects of salt concentration, pH, fixative type, dosage and type of fibrillar material on drainage were examined.
