Brief BIO: Alireza Movahedi is a PhD student at the department of chemical and biological engineering at Chalmers University of Technology. He has received his bachelor degree in Chemical engineering from University of Tehran (2006) and his master degree in Materials and Nanotechnology from Chalmers Universityof Technology(2009). He has performed his Master thesis at Technical Research Institute of Sweden (www.sp.se) on polymer-CNT nanocomposites. Ali then started as Research Engineer at Applied Surface Chemistry department, working on a project in collaboration with Capeco (www.capeco.se). The project focus was on preventing fungi and algae growth on house coatings by prolongation of the antifouling affect from biocides using microencapsulation techniques. In june 2015, Ali defended his PhD at Chalmers after which he continued his career as a post doc in the group of Kasper Moth-Poulsen.

Research: In July 2010, Ali has started as a PhD student, working on the development of new concepts for marine anti-fouling coatings. Fouling is a large problem for any man-made surface immersed into the sea, especially for transport of small and large ships. Many of the highly effective biocides used in the past for protecting the ship hull are now forbidden due to their negative environmental impacts. Copper is the most used biocide nowadays, however it has to be used in large quantities to have an acceptable performance. New regulations are introduced to limit the release into the sea and it is expected to be banned sooner or later. In fact, at present, there are no other efficient technologies to prevent fouling than the use of chemicals/biocides that slowly leak out from the coating into the sea.
Ali is developing a new coating that will attract the sea abundant copper into the coating and allow it to act as anti-fouling agent. To achieve this, Ali’s new coating absorbs copper with copper ligand functionalities that also acts as catalytic sites where the redox state of the copper changes to create a “living” coating that welcomes water into it. This is quite a different concept compared to most other coatings that are designed to keep water away from the coating. With his new technology he hopes not only to protect ships and leisure boats from fouling but also the sea from pollution. The impact of his work extends beyond antifouling applications and is also relevant fore.g. catalysis and green chemistry.
