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

该项目是首个针对高熔点(&gt；300°C)工程热塑性生物复合材料领域的研究。所选择的生物基填料包括热解生物碳，具有出色的热稳定性，例如，坚果壳生物碳具有最高分解温度&gt；590°C。它们在生物复合材料中的用途尚未报道。 生产的热稳定性石墨化生物碳将被用于加工温度超过300°C的高性能工程塑料--聚邻苯二甲酰胺(PPA)和聚苯硫醚(PPS)。热塑性生物复合材料具有理想的性能，在生物复合材料中提供更轻的重量、高机械性能和热稳定性，适用于高性能材料、电动汽车零部件和航空内饰应用。 主要的重点是利用安大略省的生物质废弃物以及各种非食用生物质，通过热解技术和各种活性金属催化剂，在~700°C到1,500°C的不同热解温度下生产高度热稳定性的石墨化生物炭。我们将在热解过程中使用活性金属催化剂，将生物质的石墨化温度从3,000°C降低到~1,500°C，最终降低能源消耗和加工成本。 该提议的创新方面是使用高石墨化生物碳和热稳定的低温热解生物碳的混合，以设计高性能生物复合材料。该项目将支持利用可持续资源开发材料，并以具有竞争力的成本将生物质废流转化为增值应用，从而产生环境效益。

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.
