Materials and composites for thermal and electrical management are increasingly important for electronic packaging because the excessive heat generated in electronic components limits the reliability, performance, and miniaturization of these electronics. In the applications which require higher thermal conductivity, such as in electronic packaging and encapsulations, satellite devices, electric cable insulation, Light Emitting Diodes LEDs, and photovoltaics solar cells, multifunctional polymer composites are becoming more commonly used. The proposed research, entitled "Smart Conductive Biobased Polymeric Composites and Their Foams," aims to bridge fundamental science to technology by investigating the processing-structure-property relationships of multifunctional biocomposites and their foams. The overall goal of this research is to design and develop light weight smart "green" composites and their foams that possess tailored multifunctional properties (i.e., electrical, thermal, and mechanical properties). In this context, the short-term objectives of this research are i) designing novel manufacturing technologies to fabricate micro-and-nano-structures of biocomposites and foams; (ii) Characterizing of the micro and nanoscopic properties and multifunctional properties of these biocomposites and their foams; (iii) Modeling and optimizing the structure-to-property relationships of the biocomposites and their foams. Successful completion of this research will represent a major contribution to the area of advanced materials and manufacturing for Canada and global manufacturing sector. In particular, this research will offer new insights to fabricate new class of green and bio-based composites with energy saving properties that can be used in lightweight electronic enclosures with tailored cooling, electrical insulating, and electromagnetic radiation shielding performances.

用于热和电管理的材料和复合材料对于电子封装越来越重要，因为电子元件中产生的过量热量限制了这些电子器件的可靠性、性能和小型化。在电子封装和封装、卫星设备、电缆绝缘、发光二极管LED和光致发光太阳能电池等需要较高导热性的应用中，多功能聚合物复合材料的应用越来越普遍。这项名为“智能导电生物基聚合物复合材料及其泡沫”的研究旨在通过研究多功能生物复合材料及其泡沫的加工-结构-性能关系，将基础科学与技术联系起来。本研究的总体目标是设计和开发轻质智能"绿色"复合材料及其泡沫，其具有定制的多功能特性（即，电、热和机械性能）。在这种情况下，本研究的短期目标是：（i）设计新的制造技术，以制造微纳米结构的生物复合材料和泡沫;（ii）表征这些生物复合材料及其泡沫的微观和纳米级性能和多功能性能;（iii）建模和优化生物复合材料及其泡沫的结构与性能关系。这项研究的成功完成将为加拿大和全球制造业的先进材料和制造领域做出重大贡献。特别是，这项研究将提供新的见解，以制造新的一类绿色和生物基复合材料的节能性能，可用于轻质电子外壳与定制的冷却，电绝缘和电磁辐射屏蔽性能。
