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导致石墨烯纳米板质（GNP）的批量生产。这为基于聚合物的新型纳米复合材料铺平了道路，该纳米复合材料能够替代以微型填充剂（例如玻璃纤维（GF））增强的常规复合材料。我们的初步研究表明，通过采用混合方法，即采用纳米和微型填充剂的组合，可以进行重大的财产改善。与当前的重型复合材料相比，这有助于轻巧多功能产品的发展，而这些复合材料以极高的微型填充物含量增强。此外，引入泡沫是迈向超轻量级产品开发的又一步。 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具有机械性能的杂化聚合物复合材料优于当前基于GF的复合材料的杂种。 （ii）开发具有电力和导热性的基本分析的多功能混合复合材料。对2021年发布的制造业的年度调查表明，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一种新兴的行业材料类别，例如汽车，航空航天，能源和微电子，通过这种协作来缩小知识和技术差距，将对加拿大制造业产生有益的链条影响。此外，该项目将允许培训和成立几位高素质的人员，最终将其专业知识带给加拿大高级制造和工程社区以及学术界。
