Advanced Multifunctional Biocomposites from Thermally Stable Biocarbon and High Performance Thermoplastic for Mobility Applications

该项目是第一个解决高熔点（> 300°C）工程热塑性生物复合材料领域的研究。所选的生物基填料包括具有出色热稳定性的热解生物碳，例如坚果壳生物碳的最高分解温度>590°C。尚未有关于其在生物复合材料中的用途的报告。生产的热稳定石墨生物碳将被纳入高性能工程塑料-聚邻苯二甲酰胺（PPA）和聚苯硫醚（PPS），这些塑料需要超过300°C的加工温度。该热塑性生物复合材料具有所需的性质，在生物复合材料中提供更轻的重量、高的机械性能和热稳定性，用于高性能材料中的应用，在电动汽车零部件和航空内部应用。主要重点将是利用安大略生物质废物以及各种非食品生物质通过热解技术生产高度热稳定的石墨生物碳，具有不同的热解温度：~700°C至1，500 °C;以及各种活性金属催化剂。我们将在热解过程中使用活性金属催化剂，以降低生物质的石墨化温度（从3，000 °C降至约1，500 °C），最终降低能源消耗和加工成本。该提案的创新方面是使用高石墨化生物碳和热稳定低温热解生物碳的混合物，以设计高性能生物复合材料。该项目将支持从可持续资源中开发材料，以具有竞争力的成本将生物质废物流转化为增值应用，从而带来环境效益。

This project is the first to address research in the area of high melting (> 300°C) engineering thermoplastic biocomposites. The chosen bio-based fillers include pyrolyzed biocarbons with outstanding thermal stability, e.g. nut shell biocarbons have maximum decomposition temperature >590°C. Their use has not yet been reported in biocomposites uses. Produced thermally stable graphitic biocarbon will be incorporated into high performance engineering plastics - polyphthalamide (PPA) and polyphenylenesulfide (PPS) that require processing temperature over 300°C. The thermoplastic biocomposites have desirable properties, providing lighter weight, high mechanical performance and thermal stability in biocomposite materials for applications in high performance materials, in electric car parts and aeronautics interior applications.The main focus will be on the utilization of Ontario biomass waste as well as various non-food biomass to produce highly thermally stable graphitic biocarbon through pyrolysis technique with various pyrolyzing temperatures: ~700°C to 1,500°C; together with various active metal catalysts. We will use active metal catalysts during pyrolysis to reduce the graphitization temperature of biomass (from 3,000°C to ~1,500°C), which ultimately reduces the energy consumption and cost of processing. The innovative aspect of the proposal is the use hybrid of highly graphitic biocarbon and thermally stable low temperature pyrolysis biocarbon, to engineer high performance biocomposites. This project will support development of materials from sustainable resources, with environmental benefits of conversion of the biomass waste streams into value-added applications, at competitive cost.
