@article{Ansari2015, abstract = {Delignified chemical wood pulp fibers can be designed to have a controlled structure of cellulose fibril aggregates to serve as porous templates in biocomposites with unique properties. The potential of these fibers as reinforcement for an epoxy matrix (EP) was investigated in this work. Networks of porous wood fibers were impregnated with monomeric epoxy and cured. Microscopy images from ultramicrotomed cross sections and tensile fractured surfaces were used to study the distribution of matrix inside and around the fibers – at two different length scales. Mechanical characterization at different relative humidity showed much improved mechanical properties of biocomposites based on epoxy-impregnated fibers and they were rather insensitive to surrounding humidity. Furthermore, the mechanical properties of cellulose-fiber biocomposites were compared with those of cellulose-nanofibril (CNF) composites; strong similarities were found between the two materials. The reasons for this, some limitations and the role of specific surface area of the fiber are discussed.}, author = {Ansari, Farhan and Sjöstedt, Anna and Larsson, Per Tomas and Berglund, Lars A. and Wågberg, Lars}, doi = {10.1016/j.compositesa.2015.03.024}, journal = {Composites Part A: Applied Science and Manufacturing}, month = {jul}, pages = {60-68}, title = {Hierarchical wood cellulose fiber/epoxy biocomposites – Materials design of fiber porosity and nanostructure}, url = {https://www.researchgate.net/profile/Farhan_Ansari/publication/274377726_Hierarchical_wood_cellulose_fiberepoxy_biocomposites_-_Materials_design_of_fiber_porosity_and_nanostructure/links/5584225808aefa35fe33d34c.pdf}, volume = {74}, year = {2015} } @article{Carosio2016, author = {Carosio, Federico and Cuttica, Fabio and Medina, L. and Berglund, L.

The nanocomposites were prepared from chemically functionalized CNCs bearing thiols. CNCs served both as reinforcing and cross-linking agents in the NR matrix, and the study was designed to prove the crosslinking function of modified CNCs. CNCs were prepared from cotton and the cross-linkable mercapto-groups were introduced onto the surface of CNCs by esterification. Nanocomposite films were prepared by dispersing the modified CNCs (m-CNCs) in NR matrix by solution casting. The cross-links at the filler-matrix (m-CNCs-NR) interface were generated by photochemically initiated thiol-ene reactions as monitored by real-time FTIR analysis. The synergistic effects of reinforcement and chemical cross-linking at the m-CNCs-NR interface on structure, thermo-mechanical and stress-softening behavior were investigated. Methods included field emission scanning electron microscopy (FE-SEM), swelling tests, dynamic mechanical analysis, and tensile tests. Compared to biocomposites from NR with unmodified CNCs, the NR/m-CNCs nanocomposites showed 2.4-fold increase in tensile strength, 1.6-fold increase in strain-to-failure, and 2.9-fold increase in work-of-fracture at 10 wt% of m-CNCs in NR.}, author = {Kanoth, Bipinbal Parambath and Claudino, Mauro and Johansson, Mats and Berglund, Lars A. and Zhou, Qi}, doi = {10.1021/acsami.5b03115}, journal = {ACS Applied Materials and Interfaces}, month = {jul}, pages = {16303-16310}, title = {Biocomposites from Natural Rubber: Synergistic Effects of Functionalized Cellulose Nanocrystals as Both Reinforcing and Cross-Linking Agents via Free-Radical Thiol-ene Chemistry}, url = {https://www.researchgate.net/profile/Qi_Zhou18/publication/279863214_Biocomposites_from_Natural_Rubber_Synergistic_Effects_of_Functionalized_Cellulose_Nanocrystals_as_Both_Reinforcing_and_Cross-Linking_Agents_via_Free-Radical_Thiol-ene_Chemistry/links/55cb164208aeca747d6a01b1.pdf}, volume = {7}, year = {2015} } @article{Lang2018, author = {Lang, Augustus W. and Li, Yuanyuan and De Keersmaecker, Michel and Shen, D.

However, we must carefully think of the effects our addiction to creating and using materials at this fast rate will have on the future generations. The way we currently make and use materials detrimentally affects the planet Earth, creating many severe environmental problems. It affects the next generations by putting in danger the future of the economy, energy, and climate. We are at the point where something must drastically change, and it must change now. We must create more sustainable materials alternatives using natural raw materials and inspiration from nature while making sure not to deplete important resources, i.e. in competition with the food chain supply. We must use less materials, eliminate the use of toxic materials and create a circular materials economy where reuse and recycle are priorities. We must develop sustainable methods for materials recycling and encourage design for disassembly. We must look across the whole materials life cycle from raw resources till end of life and apply thorough life cycle assessments (LCAs) based on reliable and relevant data to quantify sustainability. We need to seriously start thinking of where our future materials will come from and how could we track them, given that we are confronted with resource scarcity and geographical constrains. This is particularly important for the development of new and sustainable energy technologies, key to our transition to net zero. Currently ‘critical materials’ are central components of sustainable energy systems because they are the best performing. A few examples include the permanent magnets based on rare earth metals (Dy, Nd, Pr) used in wind turbines, Li and Co in Li-ion batteries, Pt and Ir in fuel cells and electrolysers, Si in solar cells just to mention a few. These materials are classified as ‘critical’ by the European Union and Department of Energy. Except in sustainable energy, materials are also key components in packaging, construction, and textile industry along with many other industrial sectors. This roadmap authored by prominent researchers working across disciplines in the very important field of sustainable materials is intended to highlight the outstanding issues that must be addressed and provide an insight into the pathways towards solving them adopted by the sustainable materials community. In compiling this roadmap, we hope to aid the development of the wider sustainable materials research community, providing a guide for academia, industry, government, and funding agencies in this critically important and rapidly developing research space which is key to future sustainability.}, author = {Titirici, Magda and Baird, Sterling G. and Sparks, Taylor D. and Yang, Shirley Min and Brandt-Talbot, Agnieszka and Hosseinaei, Omid and Harper, David P. and Parker, Richard M. and Vignolini, Silvia and Berglund, Lars A. and Li, Yuanyuan and Gao, Huai-Ling and Mao, Li-Bo and Yu, Shu-Hong and Díez, Noel and Ferrero, Guillermo A. and Sevilla, Marta and Szilágyi, Petra Ágota and Stubbs, Connor J. and Worch, Joshua C. and Huang, Yunping and Luscombe, Christine K. and Lee, Koon-Yang and Luo, Hui and Platts, M.
