Lignin-based Advanced Materials as part of a Pulp and Paper Biorefinery

碳/石墨纤维可以说是一些最重要和广泛使用的先进工程材料。 轻质抗疲劳材料，具有高强度/模量和高刚度。 先进的纤维，如碳纤维（CF）通常用于体育器材、海洋产品和运输行业。木质素是生产碳纤维的理想生物聚合物前体。 它是一种聚芳族大分子，被认为是石油的祖先。 基于木质素的产品，如碳纤维，是纸浆和纸张生物精炼战略的重要组成部分;应用生物精炼概念可以创造高价值的副产品，从而提高盈利能力并提高整个运营的效率。 木质素纤维/碳纤维提供了一个独特的机会，不仅可以提高造纸的经济性，还可以通过替代各种汽车部件中的钢材来减轻车辆重量。 该项目将研究从木质素中开发碳纤维和纳米纤维。利用先进的分离技术，我们将评估用于碳纤维生产和纤维性能的各种分级木质素制剂，并探索大规模碳纤维和纳米纤维生产的适用性。

Carbon/graphite fibres are arguably some of the most important and widely used advanced engineering marterials. Lightweight fatigue resistance materials, they possess high strength/modulus and high stiffness. Advanced fibres, such as carbon fibres (CF) are routinely being used in sports equipment, marine products, and the transportation industries.Lignin is an ideal biopolymer precursor for the production of carbon fibres. It is a polyaromatic macromolecule thought to be a petroleum progenitor. Lignin-based products such as carbon fibres are a vital component of the Pulp and paper biorefinery strategy; applying the biorefinery concept allows the creation of high-value co-products that can improve profitability and increase efficiency of the whole operation. Lignin-based fibres/carbon fibres proide a unique opportunity to not only enhance the economics of papermaking, but also reduce vehicle weight by replacing steel in various automotive components. This project will investigatethe development of carbon fibres and nanofibres from lignin. Using advanced separationtechnologies we will evaluate various fractionated lignin preparations for carbon fibre production and fibre properties, and explore the applicability for large scale carbon fibre and nanofibre production.
