Abstract poly(phenylene sulfide) brushes on glassy carbon and stainless steel

Electrochemical procedure for constructing poly(phenylene sulfide) brushes on glassy carbon and stainless steel

Kyoko Shimizu, Frances Helen Blaikie, Mikkel Kongsfelt, Kristian Damgaard Schøler Sørensen, Steen Uttrup Pedersen, Kim Daasbjerg onlinelibrary.wiley.com/doi/10.1002/pola.27893/full A simple electrochemical approach based on potential sweeping has been developed for growing poly(phenylene sulfide) (PPS) brushes from 4,4’-disulfanediyldibenzenediazonium salt on glassy carbon and stainless steel. First, the diazonium salt becomes reduced at the substrate on the initial…

Patterned Carboxylation of Graphene Using Scanning Electrochemical Microscopy

Kristian Torbensen, Mikkel Kongsfelt, Kyoko Shimizu, Emil B. Pedersen, Troels Skrydstrup, Steen U. Pedersen, and Kim Daasbjerg doi.org/10.1021/la504500m A simple, direct, and versatile scanning electrochemical microscopy (SECM) approach for local carboxylation of multilayered graphene on nickel is demonstrated, in which carbon dioxide serves as the carboxylation agent under reductive conditions in N,N-dimethylformamide. The use of…

Facile electrochemical transfer of large-area single crystal epitaxial graphene from Ir(1 1 1)

Line Koefoed, Mikkel Kongsfelt, Søren Ulstrup, Antonija Grubišić Čabo, Andrew Cassidy, Patrick R Whelan, Marco Bianchi, Maciej Dendzik, Filippo Pizzocchero, Bjarke Jørgensen http://dx.doi.org/10.1088/0022-3727/48/11/115306 High-quality growth of graphene and subsequent reliable transfer to insulating substrates are needed for various technological applications, such as flexible screens and high speed electronics. In this paper, we present a new…
