On the relationship between fibre morphology and rheology of papermaking fibres suspensions and hydrogels

纸浆是不列颠哥伦比亚省最大的出口产品，也是加拿大最大的出口产业之一。这项研究的直接目的是通过更好地了解微纤化纤维素（MFC）的生产，提高这一战略产业的竞争力。 LC磨浆是将造纸纤维打浆以提高纸张强度的过程。在极端条件下，LC精炼可以生产出一种令人兴奋的新材料MFC，这种材料正在迅速进入传统的纸浆和纸张应用。MFC是一种屈服应力流体，这项工作的目的是实现一种在线工具来测量MFC悬浮液的流变性，以达到质量控制的目的。工作的目标是建立一个统计之间的联系的MFC的介观结构与复合纸样品中的MFC的屈服应力和增强能力。一个为期2年的合作计划与Domtar（加拿大），其中研究将进行1博士后研究员和2名本科生助理

Pulp is BC's largest export and one of Canada's largest export industries. This research is directly aimed at improving the competitiveness of this strategic industry through a better understanding of the production of microfibrillated cellulose (MFC). LC refining is process in which the papermaking fibre is beaten for the purpose of enhancing paper strength. Under extreme conditions, LC refining can produce an exciting new material, MFC, which is rapidly finding inroads into traditional pulp and paper applications. MFC is a yield stress fluid and the vision of this work is to implement an on-line tool to measure the rheology of the MFC suspension for the purpose of quality control. The goal of the work is to create a statistical linkage between the mesoscopic structure of MFC with the yield stress and reinforcing ability of MFC in composite paper samples. A 2 year collaborative program with Domtar (Canada) is proposed in which the research will be conducted by 1 post doctoral fellow and 2 undergraduate assistants
