Polydopamine Interfaces in Energy Production: Functional Films and Coatings
Date, time: January 31, 2024 , 13:00 – 14:00
Speaker: Prof. Luis Emerson Coy Romero (NanoBioMedical Centre, AMU, Poznań)
Abstract:
Until recently, polydopamine (PDA) was mainly applied as a surface initiator for several biomedical applications and as a “sticky” active component sensing platform. However, several previously overlooked properties of PDA have been coming to light as research on this material continues. Here, I will mainly focus on the role of PDA coatings in energy applications, such as its apparent universal role as a photosensitizer and its behaviour when in contact with a semiconductor [1]. I will introduce some of the physicochemical aspects that make PDA an ideal coating for many photocatalytic applications, including results on various semiconducting materials and nanostructures [2]. Finally, some of the recent findings and theories on the origin of this behaviour will be presented, as well as some novel PDA architectures [3].
