Tailoring lignin through heat treatments

我们建议研究在使用各种添加剂的热加工过程中木质素性质的变化，** 关注在工业相关的聚合物加工步骤（例如，挤出、纤维 ** 纺丝和薄膜的刮刀涂布），并了解温度、加工类型和 ** 加工添加剂等因素如何用于优化木质素基材料的性能。这项工作将 ** 主要基于三种实验方法：** 1.在氧化环境下热处理各种木质素配方并评估 ** 木质素结构的变化 ** 2.使用压缩扭转DMA和拉伸DMA对特定木质素进行热分析，以确定 ** 玻璃化转变温度和储能模量的变化 ** 3.原位DMA测试，以确定最佳温度和时间，以最大限度地提高木质素材料的机械性能，包括 ** 极限拉伸强度和断裂伸长率 **。通过该项目产生的技术和专有技术预计将通过开发新的木质素基材料/技术来扩大木质素的利用，从而增加木质素的市场需求。此外，围绕这些材料/技术开发新的知识产权将使BC Research Inc.在市场上扩展和利用其Lampleforce技术包。

We propose to investigate the changes in lignin properties during thermal processing with various additives,**focusing on the changes that occur during industrially-relevant polymer processing steps (e.g., extrusion, fibre**spinning, and blade coating of thin films), and understand how the factors of temperature, processing type and**processing additives can be used to optimize the properties of lignin-based materials. This work will be**primarily based around three experimental approaches:**1.Thermal treatment of various lignin formulations under oxidative environments and evaluation of changes in**lignin structure**2.Thermal analysis of specific lignins using compressive torsional DMA and tensile DMA to determine**changes in glass transition temperatures and storage modulus**3.In situ DMA tests to determine optimal temperatures and times to maximize mechanical properties including**ultimate tensile strength and elongation at break of lignin materials.**The technology and know-how generated through this project is expected to expand the utilization of the**Lignoforce lignin through the development of new lignin-based materials/technologies, leading to increase the**market demand for lignin. Additionally, the development of new IP around these materials/technologies will**allow BC Research Inc. to extend and leverage its Lignoforce technology package in the market.
