Funding is available at the BioEnergy Laboratory of the School of Forest Resources (SFR), the University of Maine, to support one or two highly qualified M.Sc. or Ph.D. students to start in Fall 2022 or Spring 2023. 

The graduate student(s) will work on a project regarding a 3D dry thermoforming technology to make molded paper products. The research will be mainly focused on dry thermoforming process optimization and modeling to avoid fracture or other defects occurred during the thermoforming, especially in the case of deep thermoforming. The research activities will include:

• Assist in designing and fabricating paperboard materials with barriers to select gases, vapors, and liquids;
• Develop optimal thermoforming parameters to mold paperboard materials into recyclable paper products;
• Characterize the molded paper products and the influence of PFAS-free coating materials on the processing efficiency and product quality; and
• Model the thermoforming process to correlate materials, processing, and products, informing thermoforming paper products development and predicting product performance.

This project is collaborated among the USDA Forest Products Laboratory (FPL), the University of Maine’s SFR BioEnergy Laboratory, Process Development Center, and an industrial partner (a pulp and paper producer based in Maine, USA). The student(s) will work closely with professors, research scientists, and industrial partners at the three institutions to develop an innovative high-efficient 3D dry molding technology to produce PFAS-free food containers made of nanocellulose coated paperboard materials. For applicants who are pursuing a Ph.D. study, they would have an opportunity to apply for an interdisciplinary Ph.D. (I-PhD) in Materials Science and Engineering program (https://umaine.edu/graduate/program/materials-science-engineering/) after consulting with Dr. Ling Li ([email protected]) about their research interests and career plan. 

Assistantship:

An annual stipend (about $21,000 for a master’s student, about $24,000 for a Ph.D. student) paid in 12 monthly installments plus a full the Annual Health Insurance fee and full tuition waiver (up to 9 credits per semester) will be provided for an expected 20 hours per week appointment. Operating funds for conducting research and travel for attending the conference will also be available. For any inquiries or questions, please contact Dr. Ling Li at [email protected].
