Development of bio-composites made with nanocrystalline cellulose (NCC)

该项目是响应NSERC（加拿大）- ANR（法国）联合倡议的提案呼吁。在加拿大方面，参与的研究小组来自聚合物和复合材料应用研究中心（CREPEC-蒙特利尔理工学院和舍布鲁克大学）和木材研究中心（CRB-Laval大学）。在法国，这些小组来自布列塔尼材料工程师学院（LIMATB -南布列塔尼大学）、材料成型研究中心（CEMEF -巴黎矿业学院）和造纸工艺工程师学院（LGP 2-格勒诺布尔理工学院）。热塑性聚合物的性质可以通过掺入纳米尺寸的颗粒（例如纳米粘土、碳纳米管和纤维素纳米颗粒）以及在非常低的纳米填料负载量下显著改善。本项目的主要目标是开发一个新的家庭的生物复合材料从可再生材料具有相同或上级性能相比，传统的复合材料。将使用传统的注射和挤出工艺，并将开发新的机械模型，以促进其在工业应用中的引入。将使用两种热塑性聚合物基质：生物聚合物聚乳酸和石油基树脂聚丙烯。大部分的努力将致力于纳米晶纤维素（NCC）聚合物复合材料的发展。所提出的方法的独创性是将联合收割机生物基元素结合起来，使用纳米增强材料，更重要的是从概念到中试规模测试研究这些突破性材料。

This project is in response to the call for proposals in the context of the NSERC (Canada) - ANR (France) joint initiative. On the Canadian side, the participating research groups are from the Center for Applied Research in Polymer and Composites (CREPEC-École Polytechnique de Montréal and University of Sherbrooke) and the Wood Research Center (CRB-Laval University). In France, the groups are from the Laboratoire d'Ingénierie des MATériaux de Bretagne (LIMATB - Université de Bretagne-Sud), the Centre de Mise en Forme des Matériaux (CEMEF - École des Mines de Paris), and the Laboratoire de Génie des Procédés Papetiers (LGP2 - Institut Polytechnique of Grenoble). The properties of thermoplastic polymers can be significantly improved by the incorporation of nanometric size particles, such as nanoclays, carbon nanotubes and cellulosic nanoparticles, and that at a very low loading of the nanometric fillers. The main objective of the present project is to develop a new family of biocomposites from renewable materials with equal or superior properties compared to traditional composites. Conventional injection and extrusion processes will be used and new mechanical models will be developed to facilitate their introduction in industrial applications. Two thermoplastic polymer matrices will be used: a biopolymer, polylactide, and a petroleum-based resin, polypropylene. Most efforts will be devoted to the development of nanocrystalline cellulose (NCC) polymer composites. The originality of the proposed approach is to combine bio-based elements, to use nanometric reinforcements and more importantly to investigate these ground-breaking materials from conception to pilot-scale testing.
