Biodegradable Soy-Based Plastics (RFT-597)
Soy Protein Isolate (SPI) has garnered the interest of the bio-plastics community due to its low cost, desirable transparency and film forming ability. However, poor mechanical strength, flexibility and water resistance have hindered the commercialization of SPI bioplastics. To overcome these fundamental limitations, researchers at NDSU have developed novel SPI based bioplastic formulations reinforced with cellulose nanofibers. The fabrication process combines photo-crosslinking and nanofiller reinforcement, evading the harsh solution and melt processing-based methods. Hence the resulting UV cured bio-plastics formulation retains all the inherent characteristics and exhibits improved physical properties as compared to traditional, petroleum-based plastics. The resulting bioplastics can be used to manufacture biodegradable solid articles of varying shapes and sizes, that are useful in a variety of applications.
