Canada's plastic industry is a multi-faceted sector worth more than $50.9 billion with over 3,757 companies and 171,000 workers [Canadian Plastics Industry Association (CPIA)]. Growing concerns about the environmental impacts of polymers have encouraged the plastic industry to produce biodegradable products. However, existing biodegradable polymers do not meet the requirements for many applications due to the lack of proper functionality or processability challenges. Polymer-based multilayer products are a viable option to incorporate biodegradable materials to produce partially or fully biodegradable products while introducing functionalities such as stimuli responsiveness, impact, optical properties, and barrier properties to the material. The development of advanced multilayer products is at its infancy due to existing challenges in product design and process. ***To address these challenges, the long-term goal of this research program is to develop value-added biodegradable multilayer products. This will be achieved through understanding structure-process-properties relationships and developing best processing strategies. This objective serves Canada's economy in terms of developing advanced functionalized multilayer products and introducing new processing strategies in manufacturing these products. Canadian companies including Husky Injection Molding Systems, Solvay, Shawcor, Ingenia and Solegear are interested in resolving such challenges.***The short-term objectives (STO's) of this program are as follows: STO1-To develop advanced functional multilayer products by incorporating temperature, pressure, pH and light responsive layers with engineered micro and nanostructures. The focus of this STO will be on the use of biopolymers. STO2-To develop best processing practices through quantifying (i) viscoelastic instabilities such as slippage, secondary flows, interfacial layer nonuniformity; and (ii) interfacial strength as a function of material, process, and design parameters. STO3-To investigate and model the structure-process-property relationship of the fabricated advanced multilayer products (i) in simple and complex geometries; (ii) in linear and non-linear viscoelastic regions; and (iii) adjacent to elastic and plastic-walls.***The proposed research program will contribute to the training of seven HQP by engaging both graduate and undergraduate students. Our research team will investigate the rich research topics by developing rigorous rheological models, using advanced experimental techniques (e.g. rheological experimentation, visualization, and characterization experiments). The proposed research is important not only to develop advanced functionalized products but also, to find practical solutions to produce environment-friendly products. Such a development will benefit Canada's plastics industry, more particularly in Ontario, and will strengthen their competitiveness in the global markets.

加拿大塑料行业是一个多元化行业，价值超过 509 亿加元，拥有超过 3,757 家公司和 171,000 名工人 [加拿大塑料工业协会 (CPIA)]。人们对聚合物对环境影响的日益关注促使塑料行业生产可生物降解的产品。然而，由于缺乏适当的功能或可加工性挑战，现有的可生物降解聚合物不能满足许多​​应用的要求。基于聚合物的多层产品是结合可生物降解材料来生产部分或完全可生物降解产品的可行选择，同时为材料引入刺激响应性、冲击力、光学性能和阻隔性能等功能。由于产品设计和工艺方面存在挑战，先进多层产品的开发还处于起步阶段。 ***为了应对这些挑战，该研究计划的长期目标是开发增值的可生物降解多层产品。这将通过理解结构-过程-特性关系并制定最佳加工策略来实现。这一目标在开发先进的功能化多层产品和在制造这些产品时引入新的加工策略方面为加拿大经济服务。 Husky Injection Molding Systems、Solvay、Shawcor、Ingenia 和 Solegear 等加拿大公司有兴趣解决此类挑战。***该计划的短期目标 (STO) 如下： STO1-通过整合开发先进的功能性多层产品具有工程微米和纳米结构的温度、压力、pH 和光响应层。本次 STO 的重点将是生物聚合物的使用。 STO2-通过量化 (i) 粘弹性不稳定性（例如滑移、二次流、界面层不均匀性）来开发最佳加工实践； (ii) 界面强度作为材料、工艺和设计参数的函数。 STO3-研究和模拟所制造的先进多层产品（i）在简单和复杂几何形状中的结构-工艺-性能关系； (ii) 在线性和非线性粘弹性区域； (iii) 邻近弹性墙和塑料墙。***拟议的研究计划将通过研究生和本科生的参与，为七个 HQP 的培训做出贡献。我们的研究团队将通过开发严格的流变模型，使用先进的实验技术（例如流变实验、可视化和表征实验）来研究丰富的研究主题。所提出的研究不仅对于开发先进的功能化产品很重要，而且对于寻找生产环保产品的实用解决方案也很重要。这样的发展将有利于加拿大的塑料工业，特别是安大略省的塑料工业，并将增强其在全球市场的竞争力。
