Abstract

The transcription of nanoproperties to other dimensions in an efficient and simple way by the appropriate design of devices is a challenge, and conductive nanocarbon systems are considered here. The evaporation-induced self-assembling method is proposed to form branched, fractal-like ā€œ2Dā€ conductive macrostructures from (nano) micro few-layer graphene flakes. The self-assembled conductive graphene networks reveal a reduction of percolation threshold compared to a random arrangement (a lower matter concentration is required to make a given substrate conductive and at a lower coverage), and become a promising matrix for conductive (transparent) films. The method is easy, cost-efficient and can potentially be applied on unlimited surfaces.

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.
