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

该项目是第一个致力于高熔点（> 300°C）工程热塑性生物复合材料领域研究的项目。所选择的生物基填料包括具有出色热稳定性的热解生物碳，例如坚果壳生物碳具有最高分解温度>590°C。它们在生物复合材料中的应用尚未见报道。生产的热稳定石墨生物碳将被纳入高性能工程塑料-聚苯二胺（PPA）和聚苯硫醚（PPS），这些塑料需要300°C以上的加工温度。热塑性生物复合材料具有理想的性能，为高性能材料、电动汽车零件和航空内饰的生物复合材料提供了更轻的重量、高的机械性能和热稳定性。主要重点将是利用安大略省的生物质废弃物以及各种非食品生物质，通过热解技术生产高热稳定性的石墨生物碳，热解温度：~700°C至1,500°C；与各种活性金属催化剂配合使用。我们将在热解过程中使用活性金属催化剂，降低生物质的石墨化温度（从3000℃降至~ 1500℃），最终降低能耗和加工成本。该提案的创新之处在于使用高石墨生物碳和热稳定的低温热解生物碳的混合物来设计高性能的生物复合材料。该项目将支持从可持续资源中开发材料，并以具有竞争力的成本将生物质废物流转化为增值应用的环境效益。

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.
