The production and use of bioplastics has seen explosive growth world-wide in recent years driven by global environmental concerns, persistent waste disposal challenges and consumer demand for sustainable products. Key challenges associated with more wide-spread acceptance of bioplastics in consumer and engineering applications are their high production costs, brittle nature, poor thermal stability, slow crystallization rates and low melt strength, which restrict their processability under common polymer processing operations and have limited their applications to low-value, commodity applications. The proposed discovery grant research program has the long term objective to implement economically viable, solvent-free, environmentally friendly processes to obtain fully bio-based products, with excellent engineering properties that will serve as credible replacements to conventional commodity and engineering polymers. The program will focus on the development and full characterization of biopolymer formulations, which target specific areas of application, according to the following short-term objectives. a) Development of bioplastic-based compounds and composites as replacements for conventional thermoplastic olefin and thermoplastic vulcanizate blends, suitable for automotive applications. b) Production of light-weight, rigid cellular plastics (foams), which will be used as replacements of conventional foams. Applications in automotive and other industries are envisioned, with a special focus on the production of nanocellular foams with superior insulating properties. c) 3D printing/additive manufacturing of biopolyester-based microfibers and mats suitable for biomedical applications. The proposed research program will train highly qualified personnel in a wide-array of skills in materials science, processing and sustainable technologies. This research can lead to a great breakthrough in the technology of bioplastics, by developing economically viable, solvent-free, environmentally friendly processes to obtain fully bio-based products, with excellent engineering properties that can gain wide-spread consumer acceptance, while providing a sustainable and environmentally friendly solution. The outcome of this research is expected to benefit Canadian manufacturers by providing them with innovative materials and processes to produce environmentally friendly, high-value-added products based on novel biobased and/or biodegradable materials. Additionally this research will generate new and valuable scientific insights and will foster the development of new materials in the rapidly growing field of additive manufacturing/3D printing applications.

近年来，由于全球环境问题，持续的废物处置挑战以及消费者对可持续产品的需求，生物塑料的生产和使用在全球范围内爆炸性增长。与在消费者和工程应用中更广泛接受生物塑料相关的关键挑战是其高生产成本，脆弱性，较差的热稳定性，缓慢的结晶速率和低熔体强度，这限制了在共同聚合物处理操作下的可加工性，并且限制了其对低价值，商品应用的应用。 拟议中的发现赠款研究计划具有长期目标，可以实施经济上可行的，无溶剂，环保的流程，以获得完全基于生物的产品，并具有出色的工程特性，可作为传统商品和工程聚合物的可靠替代者。该计划将侧重于根据以下短期目标来针对特定应用领域的生物聚合物配方的开发和全面表征。 a）开发基于生物塑料的化合物和复合材料，以替代适用于汽车应用的常规热塑性烯烃和热塑性硫化硫酸盐混合物。 b）产生轻质，刚性细胞塑料（泡沫），将用作替代常规泡沫的替代品。设想在汽车和其他行业中的应用，特别关注具有优质绝缘性能的纳米细胞泡沫。 c）基于生物的微纤维和垫子的3D打印/添加剂制造适用于生物医学应用。 拟议的研究计划将在材料科学，加工和可持续技术方面的广泛技能中培训高素质的人员。 这项研究可以通过发展经济上可行的，无溶剂，环保的流程来获得完全基于生物的产品，并具有出色的工程特性，可以获得广泛的消费者接受，同时提供可持续的和环保的解决方案，从而获得了生物塑料技术的巨大突破。这项研究的结果有望通过为加拿大制造商提供创新的材料和工艺来使加拿大制造商受益，以生产基于新型生物基和/或可生物降解材料的环保，高价值的产品。此外，这项研究将产生新的和有价值的科学见解，并将促进在添加剂制造/3D打印应用程序快速增长的领域的开发。
