Functional Surfaces for Radiodecontamination

Abstract : Nuclear energy is the true engine of our modern day society and seen as the most efficient and clean form of energy. At the same time, it is the source of many concerns, with its highly radiotoxic waste produced by nuclear reactors and the public health and environmental risks that follow nuclear accidents. In this context, the aim of this project was to come up with new innovative materials, capable of efficiently trap radionuclides in contaminated aqueous media. A new polymer is reported and synthesized in solution as a free polymer, using the easy, cheap and fast metallic copper-mediated controlled radical polymerization (Cu0-CRP). The new polymer was also built from different substrates like PET and PVC, the latter being the most efficient. These new materials were later put to test and proved to be highly performing in trapping uranium and many lanthanides in water. These results have many implications in the nuclear industry. They can be used to harvest uranium from seawater as a future renewable energy source. They can also help the nuclear waste management industry. They are also a potential candidate for treating radio-contaminated environments and for radiodetoxification of living species, including humans.
