6. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish
University essay from Uppsala universitet/Tillämpad mekanikAbstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

7. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials
University essay from KTH/MaterialvetenskapAbstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

8. The effect of fiber structure on chemical modification of cellulosic fibers
University essay from KTH/KemiteknikAbstract : För att skapa ett hållbart samhälle måste material av fossilt ursprung ersättas med förnyelsebara och miljövänliga alternativ. Ett sådant alternativ är cellulosa från vedfibrer, som har stor potential att kunna ersätta många fossila material i framtiden. READ MORE

9. A Study on Lignin or Zein Based Hydrophobic Coatings
University essay from Lunds universitet/Kemiteknik (CI)Abstract : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. READ MORE

10. ROP in novel biobased ionic liquids towards cellulose functionalization
University essay from KTH/Fiber- och polymerteknologiAbstract : Ett nytt sätt att aktivera cellulosa för kemisk modifiering med hjälp av en miljövänlig process har utvecklats innan starten av detta projekt. Två versionen av den nyskapade betain-baserade jonvätskan, BBIL har syntetiserats, en som använder mesylat som motjon, M-BBIL och en som använder acetat, A-BBIL. READ MORE
