The harvest of natural resources is the backbone of the thriving Canadian economy. Without a viable pulp and paper industry it is not possible to have a viable forestry industry. Traditionally, BC and Canada's pulp and paper sector has been a newsprint exporter to the US market. The recent economic downturn, coupled with disruptive technologies for paperless communication, has resulted in a 40% reduction in newsprint and communication paper consumption. This turning point means that the forest industry's survival depends on Canada's ability to develop innovative new uses for high quality BC wood fibres. Despite these market changes, the future of the forest industry in BC and Canada is bright-green, and the timing for a broader consumer acceptance of fibre based materials and products may never be better. Our shifting focus on the environment and climate change makes the use of natural wood fibre a significantly planet friendly choice over traditional fossil based and other non-renewable materials. Historically, before the plastic revolution, fibre was the dominant material for many consumer level products, including clothing, wall coverings, carpet underlay, and of course, grocery bags. We expect to be constructing houses from trees for the foreseeable future and as a result there will be an abundance of high quality residual wood fibre. The competitiveness of the forest industry is dependent on the ability to extract high value fibre to create novel products or processes. This proposal addresses a novel platform technology, i.e. hydrodynamic focussing coupled with reactive multi-fluid layering to develop novel composite products from cellulose micro-fibrils. This production methodology is based upon bio-mimicry of the production of a spider's silk with the goal of producing high performance bio-composites such as threads, filaments, hollow tubes or films. If feasible, parallelization for industrial production is immediately possible. A three year project is proposed to be conducted by one Post-Doctoral fellow.

自然资源的收获是加拿大经济繁荣的支柱。没有一个可行的纸浆和造纸工业，就不可能有一个可行的林业。传统上，不列颠哥伦比亚省和加拿大的纸浆和造纸部门一直是美国市场的新闻纸出口商。 最近的经济衰退，加上无纸化通信的颠覆性技术，导致新闻纸和通信纸的消耗量减少了40%。 这一转折点意味着林业的生存取决于加拿大开发高质量BC木纤维创新用途的能力。 尽管市场发生了这些变化，但BC省和加拿大林业的未来是光明的，更广泛的消费者接受纤维材料和产品的时机可能永远不会更好。我们对环境和气候变化的关注不断转移，使天然木纤维的使用成为对地球友好的选择，而不是传统的化石材料和其他不可再生材料。从历史上看，在塑料革命之前，纤维是许多消费级产品的主要材料，包括服装，墙壁覆盖物，地毯，当然还有杂货袋。我们预计在可预见的未来将用树木建造房屋，因此将有大量高质量的残余木纤维。林业的竞争力取决于提取高价值纤维以创造新产品或工艺的能力。 该提案提出了一种新的平台技术，即流体动力学聚焦与反应性多流体分层相结合，以开发来自纤维素微纤维的新型复合材料产品。这种生产方法是基于蜘蛛丝生产的生物模拟，目的是生产高性能的生物复合材料，如线，丝，中空管或膜。如果可行，工业生产的并行化立即成为可能。一个为期三年的项目拟由一名博士后进行。
