Recent advancements in nanomanufacturing have led to the mass production of graphene nanoplatelets (GnP). This has paved the way for novel polymer-based nanocomposites capable of replacing conventional composites reinforced with micro-sized fillers, such as glass fibers (GF). Our preliminary studies have demonstrated significant property improvements by taking a hybrid approach, i.e., employing a combination of the nano- and micro-sized fillers. This significantly contributes to the development of lightweight multifunctional products compared to the current heavy composites reinforced with extremely high micro-sized filler contents. Moreover, the introduction of foaming is another step towards the development of ultralightweight products. Therefore, the proposed project aims to achieve a fundamental understanding on the materials/processing parameters, that are applicable for the multi-scale development of novel nanocomposites and foams.The proposal outlines a comprehensive, systematic study, on developing lightweight multifunctional nanocomposites as effective replacements for conventional products, following two primary objectives: (i) development of ultralightweight GF and GnP-reinforced hybrid polymer composites with mechanical properties being superior to those of the current GF-based composites; (ii) development of multifunctional hybrid composites with fundamental analyses of the electrical and thermal conductivities.The annual survey of manufacturing industries released in 2021 demonstrates that manufacturing is a cornerstone of Canada's economy (~$750 billion). Bearing in mind that multifunctional polymer nanocomposites are an emerging class of materials in industries, such as automotive, aerospace, energy, and microelectronics, closing the knowledge and technology gaps through this collaboration would cause a beneficial chain effect on Canada's manufacturing sectors. Additionally, this project will allow for the training and formation of several highly qualified personnel, which will eventually bring their expertise to the Canadian advanced manufacturing and engineering community, as well as to academia.

纳米制造的最新进展已经导致石墨烯纳米片（GNP）的大规模生产。这为新型聚合物基纳米复合材料铺平了道路，该复合材料能够取代用微米级填料（如玻璃纤维（GF））增强的传统复合材料。我们的初步研究表明，通过采用混合方法，即，使用纳米和微米尺寸填料的组合。与目前使用极高的微米级填料含量增强的重型复合材料相比，这大大有助于开发轻质多功能产品。此外，发泡的引入是超轻产品开发的又一步。因此，该项目旨在对适用于新型纳米复合材料和泡沫的多尺度开发的材料/工艺参数进行基本了解。该项目概述了一项全面、系统的研究，旨在开发轻质多功能纳米复合材料，作为传统产品的有效替代品，以下两个主要目标：（i）开发超轻质GF和GNP增强的混合聚合物复合材料，其机械性能上级现有的GF基复合材料;（二）发展多功能混杂复合材料，并对导电性和导热性进行基本分析。二零零一年出版的制造业按年统计调查2021年表明制造业是加拿大经济的基石（约7500亿美元）。考虑到多功能聚合物纳米复合材料是汽车、航空航天、能源和微电子等行业的新兴材料类别，通过这种合作缩小知识和技术差距将对加拿大的制造业产生有益的连锁效应。此外，该项目还将培训和培养几名高素质的人员，最终将他们的专业知识带到加拿大先进的制造业和工程界以及学术界。
