Abstract

Besides chemical functionalisation, the use of surfactants can be applied to debundle and disperse carbon nanotubes before further application in polymer nanocomposites. In this work we present a theoretical analysis of the interaction between single-walled carbon nanotubes and sodium dodecyl sulfate as surfactant and/or polystyrene as polymer matrix using semi-empirical AM1 calculations. Results indicate that the use of short potassium sulfate-terminated polystyrene chains as an extra component can help to remove the surfactant from the nanotube surface within the matrix, resulting in improved electronic properties of the nanocomposite.

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.
