Vegetable Oil-Based Polymers for Nanoparticle Surface Modification (RFT-413)

Invention Summary


The extremely high surface area of nanoparticles provides many advantages over conventional particles with dimensions in the micron scale. For a variety of applications, it is necessary to suspend the nanoparticles in a liquid medium. Researchers at NDSU have developed a new plant-oil-based polymer technology focused on the application of nanoparticle suspension in water. One primary example of this technology application is its use as a protectant while dispersing and suspending iron nanoparticles in decontamination efforts involving chlorinated hydrocarbons, such as tetrachloroethylene. The copolymers described herein are not only highly effective with respect to suspending nanoparticles in water, but also exhibit high biodegradability. Biodegradability is important for environmental applications because the polymer is typically not recovered after treatment of a groundwater contaminant plume. In addition, compared to other approaches, this copolymer technology enables compositions to be highly tailored or optimized for a given nanoparticle and application.
