Researchers develop a PLA cup that can withstand boiling water

Source：University of Akron Date：2021-01-21

A University of Akron (UA) professor’s latest development in bioplastics has the potential to make important strides in sustainability for future plastics.

 

In the lab of Dr. Shi-Qing Wang in UA’s School of Polymer Science and Polymer Engineering, the team is focusing on research that showcases effective strategies for turning brittle polymers into tough and flexible materials.

 

For example, the group has recently produced a prototype poly(lactic acid) (PLA) cup that is transparent, super tough and does not shrink when filled with boiling water.

 

By investigating the origin of ductility in semicrystalline polymers, Wang’s research group discovered a way to limit crystals to nanoscopic scales in PLA while preserving the network, resulting in the clear, tough and heat resistant cup. Such a transparent cup can hold hot tea and coffee and could replace most plastic beverage cups on the market.
