Abstract Details

2018, Master of Science, University of Akron, Polymer Science.
Resilience is the ability of a material to absorb energy during elastic deformation and to release the stored energy upon unloading. Natural proteins such as resilin and elastin exhibit high resilience up to 92% under large strain and low stress. It has been known that high resilience of natural resilin results from a well-defined network along with low intermolecular friction. Much effort has been put into developing highly resilient synthetic materials based on this strategy and applied in soft tissue engineering, most notably hydrogels and bottlebrush polymers. Unfortunately, the potential dehydration of hydrogels and time-consuming synthesis of bottlebrush macromolecules limit their real-world applications. In recent years, soybean oil sourced elastomers have emerged as promising soft elastic resilient materials. Various modifications are introduced to construct controlled networks, and some of them succeed from the engineering perspective. However, detailed role of each fatty acid from soybean oil in high resilience property remains obscure considering the complex and diverse composition of natural soybean oil. Moreover, none of them try to construct biodegradable, high resilience elastomer originated from soybean for soft tissue engineering applications. Herein, we develop polyester system with control over fatty acid chemical structure, study the entanglement by rheology tests and further relate it to the resilience performance of resulting elastomer. The results will contribute to the basic understanding and future applicability of soft elastomers originated from vegetable oil. Furthermore, a biodegradable, highly resilient soft elastomer is designed and has the potential for soft tissue engineering applications.
