Paper on “Biobased Structurally Compatible Polymer Blends Based on Lignin and Thermoplastic Elastomer Polyurethane as Carbon Fiber Precursors” published

Culebras, M., Beaucamp, A., Wang, Y., Clauss, M. M., Frank, E., & Collins, M. N. (2018). Biobased structurally compatible polymer blends based on lignin and thermoplastic elastomer polyurethane as carbon fiber precursors. ACS Sustainable Chemistry & Engineering, 6(7), 8816-8825. DOI: 10.1021/acssuschemeng.8b01170 Open access: http://hdl.handle.net/10344/6912 Abstract The production of carbon fibers based on lignin reduces the cost and the environmental impact associated with carbon fiber manufacturing. However, the melt processing of lignin as a carbon fiber precursor is challenging due to its brittleness and limited…

Paper on “Understanding the Thermal and Dielectric Response of Organosolv and Modified Kraft Lignin as A Carbon Fibre Precursor” published

Culebras, M., Sanchis, M.J., Beaucamp, A., Carsí, M., Kandola, B.K., Horrocks, A.R., Panzetti, G., Birkinshaw, C. and Collins, M.N., 2018. Understanding the thermal and dielectric response of organosolv and modified kraft lignin as a carbon fibre precursor. Green Chemistry, 20(19), pp.4461-4472. DOI: 10.1039/C8GC01577E Open access: http://hdl.handle.net/10344/6963 Abstract Understanding the thermal behaviour of lignin is crucial in order to realise its valorisation as an engineering polymer. Two hardwood lignins, organosolv (OSL) and chemically modified kraft lignin (ML) have been chosen to represent important classes of…

Paper on “Bio‐derived Carbon Nanofibres from Lignin as High‐Performance Li‐Ion Anode Materials” published

M. Culebras, H. Geaney, A. Beaucamp, P. Upadhyaya, E. Dalton, K. M. Ryan, M. N. Collins, ChemSusChem 2019, 12, 4516. DOI: 10.1002/cssc.201901562 Open access: http://hdl.handle.net/10344/8055 Abstract Development of cost‐effective and increasingly efficient sustainable materials for energy‐storage devices, such Li‐ion batteries, is of crucial future importance. Herein, the preparation of carbon nanofibres from biopolymer blends of lignin (byproduct from the paper and pulp industry) and polylactic acid (PLA) or a thermoplastic elastomeric polyurethane (TPU) is described. SEM analysis shows the evolving microstructural morphology after each processing…

Paper on “Effect of Atmospheric Pressure Plasma Treatment of Glass Fibers on the Composite Strength of Endless Fiber-Reinforced Injection Molded Components” published

Gebken, T., Sachs, R., Kühn, M., Ihde, J., Dröder, K., & Wilken, R. (2019). Effect of Atmospheric Pressure Plasma Treatment of Glass Fibers on the Composite Strength of Endless Fiber-Reinforced Injection Molded Components. Key Engineering Materials, 801, 251–257. DOI: 10.4028/www.scientific.net/kem.801.251 Abstract: Injection molding is an efficient manufacturing process for short-fiber reinforced plastic components and is used for the production of semi-structural or geometrically complex components. To improve stiffness and strength, continuous fibers can be locally integrated inside the part during manufacturing.…

Paper on “Treatment of Flax Fabric with AP-DBD in Parallel Plane Configuration” published

Sachs, R.; Ihde, J.; Wilken, R.; Mayer, B. Treatment of Flax Fabric with AP-DBD in Parallel Plane Configuration. Plasma 2019, 2, 272-282. DOI: 10.3390/plasma2020019 Abstract For the use of natural fibers in composite materials it is often necessary to improve the compatibility between fiber (sizing) and polymer matrix systems, e.g., by increasing the number of functional groups on the fiber surfaces. In this work, a dielectric barrier discharge (DBD) source in plane configuration is used to treat flax fabrics in ambient air. It…

Paper on “Allocation in Life Cycle Assessment of Lignin” published

Hermansson, F., Janssen, M. & Svanström, M. Allocation in life cycle assessment of lignin. Int J Life Cycle Assess 25, 1620–1632 (2020). DOI: 10.1007/s11367-020-01770-4 Abstract Purpose Lignin extraction in pulp mills and biorefineries are emerging technologies. Lignin is always the product of a multi-output process. Assessing such processes using life cycle assessment (LCA) requires the environmental impacts to be divided between the co-products of the system, referred to as allocation. This article explores different allocation approaches for lignin and illustrates the influence of the…
