Interactions of polymers with reduced graphene oxide: van der Waals binding energies of benzene on graphene with defects
Literature Information
Mohamed Hassan
The interaction of benzene molecules with various defects in graphene is studied using density functional theory enhanced by two different recent dispersion corrections. Both provide the same qualitative picture: the binding strength of benzene to the various defects is governed by steric hindrance. Our first principles calculations in combination with a simple model predict reduced stabilities of polymer–graphene nanocomposites made of reduced graphene oxides depending on the defect density. Above ∼15% defect coverage the interaction is lowered to roughly one third as compared to pristine graphene.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
