The proposed program targets research into the conversion of naturally abundant forest residual biomass into high-performance functional bioproducts through cost-effective and energy-efficient means. New chemistry and technologies will be developed to 1) efficiently isolate and modify lignocellulosic nanomaterials (LCNs); 2) assemble the isolated LCNs into advanced structures; and 3) advance the emerging energy and electronic related applications. The proposed program is unique and novel in combining the whole materials development process, covering lignocellulosic biomass fractionation and isolation, chemical modification, structural design and assembly, as well as advanced applications. The following research approaches will be explored, including isolating LCNs from high lignin-content biomass using recyclable solvents; constructing high-performance hierarchical structures using 3D printing, foam forming, film formation, etc.; exploring cellulose-cellulose and cellulose-water interactions to develop high performance structure; and developing super-strong, tough, and stretchable cellulosic ionic conductors for electronics and energy storage applications. The following outcomes are expected to be generated through my proposed research program, including, new technologies and chemistry will be developed to produce LCNs with increased yield and tunable surface chemistry, which can promote the improvement on the the mechanical performance and structural efficiency for packaging, lightweight vehicles, and building and construction materials, as well as to generate fundamental knowledge about ion conduction mechanisms for emerging applications. In addition, the research outcomes will translate into high impact journal publications, patent applications, and products with commercial potential. High quality personnel (HQPs) will be trained for the sustainable industries. Overall, my proposed research program will elevate Canada’s research and development capabilities in the circular bioeconomy.
