In the spring of 2020, I started my PhD life in the College of Forest Resources and Environmental Science at Michigan Technological University. Under the guidance of Prof. Xinfeng Xie, I have been doing research on the recovery of Kraft lignin from black liquor and its application in polyurethane foams. In my research, I developed a new one-pot liquefaction process to recover Kraft lignin with tunable and predicable yield and molecular properties directly from black liquor. Then, the lignin was used to partially replace the fossil-based polyols to prepare polyurethane foams. I wish my research can contribute to the sustainable development of both pulping and polyurethane industries.
I would like to thank the College of Forest Resources and Environmental Science and the Graduate School for their support in my PhD life here. I also really thank the continuous support from my advisor Prof. Xinfeng Xie, committee members, and my lab members.
