Bioplastics

Post Doctoral Research Associate: Xiaoying Zhao

Xiaoying’s area of interest is the development of bio-based composites for food packaging applications. We tailor the properties of the PHBV bioplastic by incorporating natural rubber to make it more flexible and processable. We utilize thermal, mechanical, and rheological analysis to fully characterize the PHBV/natural rubber composite and subsequently assess the stability of the trays made from the composites with high and low acid food under freezing and microwaving. This research would serve for future commercialization of the PHBV/natural rubber food trays and provide helpful information for future research on the development of bioplastics for microwave packaging applications.

Researcher: Sam Storts

Sam’s area of study is similar to that of Xiaoying’s as he works with her in designing experiments to observe the possible optimization techniques available in making bioplastics out of PHBV. The focus of Sam’s work is on the development of bio-based plastic films with the hopes of producing a biodegradable film made of environmentally beneficial materials. The brittleness issue associated with films made from PHBV is being addressed in the same way as Xiaoying’s plastic trays: with the incorporation of natural rubber. The production of the films was the first step in the process. Experiments determining the tensile properties as well as safeguarding measures are to be performed to ensure a safe and viable alternative to the currently used petroleum resins.
