1. Biobased carbon fibers from solution spun lignocellulosic precursors
Abstract : Carbon fibers (CFs) have excellent mechanical properties and a low density, making themattractive as a reinforcing fiber in composites. The use of CFs is limited to high-end applications,since they are produced from an expensive fossil-based precursor via an energy-intensivemanufacturing process, explaining the need for cheaper CFs from renewables.

3. Air-gap spinning of lignin-cellulose fibers
Abstract : Co-processing of lignin and cellulose, the two main constituents of wood, has previously been identified as a potential route for the production of inexpensive and bio-based carbon fibers. The first step in this process is to spin a precursor fiber. READ MORE

4. Cellulose processing in ionic liquid based solvents
Abstract : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. READ MORE

5. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure
Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE
