CSMS researcher Dr. Dilpreet Bajwa, North Dakota State University professor of mechanical engineering, and CRCS researcher Dr. Kerry Hartman, environmental science faculty member and academic dean at Nueta Hidatsa Sahnish College are conducting research on biodegradable polymers. They are looking into food packaging developed from bio-based polymers, with a focus on the use of polylactic acid, also known as PLA, and ways to enhance PLA film characteristics.

The collaborative idea was sparked by an ND EPSCoR Emerging Areas Seed award opportunity that provides funding for collaborations between ND EPSCoR’s CSMS and CRCS research centers. Their collaborative research may result in a patent and has the potential to translate into new applications in the food packaging industry as well as in other industries.

 

ND EPSCoR funding is provided by the State of North Dakota and NSF EPSCoR Research Infrastructure Improvement Program Track-1 (RII Track-1) Cooperative Agreement Award OIA-1355466.

More information about the collaboration between Drs. Hartman and Bajwa can be found in the NDSU News announcement.

Following is the abstract from the journal article:

Formulations of bio-based poly(cyclic carbonates) and amines using cooperative catalysis were studied to produce non-isocyanate polyurethanes (NIPUs). Concerns on the use of isocyanates as starting materials for polyurethanes (PUs) have risen due to their effects on human health after exposure and also because their synthesis involves the use of phosgene. Polyurethanes are highly versatile materials used in widespread industries such as automotive, building, construction, and packaging. They have also been used as flexible and rigid foams, adhesives, coatings, thermoplastic, or thermoset materials. Traditionally, PUs are synthesized from polyols and polyisocyanates. In order to circumvent the concerns, much research has been devoted to exploring alternative approaches to the synthesis of PUs. NIPU synthesis using cyclic carbonates and amines has gained popularity as one of the new approaches. In this study, novel bio-based resins were synthesized by converting epoxidized sucrose soyate into carbonated sucrose soyate (CSS) under supercritical conditions. Initial studies have shown promise in systems where CSS is crosslinked with multifunctional amines generating coatings with good solvent resistance. This work focused on studying the effect of catalysts and developing formulations of bio-based non-isocyanate polyurethane coatings.
