Thermoplastics materials play an important role in our everyday lives. Although polyethylene and polypropylene have a simple chemical structure, without these simple plastics we could not conceive the level of technology that we have today in transportation, communication, food, safety and healthcare. In the final applications these plastics are mixed with additives to reach a balance of performance and cost. Materials based on minerals, like talc and glass fiber, represent the most common type of material added to thermoplastics. Over the last 10 year, our research group has developed new ways to disperse nanoparticles of mineral materials in polyethylene and polypropylene. Polymer nanocomposites are materials for which nanoparticles (particles smaller than 100nm) are dispersed in the plastic matrix. The categories of nanocomposites that our research group has worked on include clays (montmorillonite) and nanopowders (nano-alumina, nano-titania and nano-silica). We discovered and developed methods for preparation of hybrid polymer nanocomposites using a method called in situ polymerization. The new research proposed here will move towards the utilization of unconventional nanoparticles that are produced from renewable resources. Instead of using nanoparticles from minerals, this new research will use nanocrystalline cellulose for the preparation of polymer nanocomposites containing biobased materials. Nanocrystalline cellulose is seen as a high value added material for the Canadian forestry sector. The research proposed here will create technology to deploy nanocrystalline cellulose made in Canada in many different types of products used in everyday life, thus leading to a new market in automotive, building, packaging and energy sectors for Canadian resources.

热塑性塑料材料在我们的日常生活中扮演着重要的角色。虽然聚乙烯和聚丙烯的化学结构很简单，但如果没有这些简单的塑料，我们就无法想象我们今天在交通、通讯、食品、安全和医疗保健方面的技术水平。在最后的应用中，这些塑料与添加剂混合，以达到性能和成本的平衡。基于矿物的材料，如滑石和玻璃纤维，是添加到热塑性塑料中最常见的材料类型。
