“…61) and a surface tension of only 20.34 mN m −1 , satisfying both criteria. From the wide range of possible graphene ink preparation methods, 50,62–64 we select sonication-assisted LPE due to its simplicity and compatibility with low-boiling solvents. 52 We sonicate 500 mg of graphite in 50 mL IPA for 9 hours stabilised by small quantities (20 mg) of the biocompatible polyvinylpyrrolidone (PVP) to enable achieving the required concentration and improving the ink shelf life.…”

“…Graphene is defined as a single-atom flat monolayer made of sp 2 -hybridized ‘honeycomb’ carbon lattice [ 1 – 3 ]. During the past two decades, scientists have discovered numerous unique properties of graphene such as high optical performance [ 4 ], high charge carriers mobility (due to electric field effect) [ 5 ] and thermal conductivity [ 6 ], and demonstrated a significant number of potential applications for this material in its ‘gold rush’ years [ 2 , 7 ], covering different areas including field emission [ 8 , 9 ], gas and biosensors [ 10 , 11 ], field-effect transistors [ 5 ], transparent electrodes [ 4 , 12 ], coatings [ 1 ], batteries [ 13 , 14 ] and printed electronics [ 15 , 16 ]. However, the progress of the devices mentioned above relies upon large-scale industrial production of graphene, which remains a major challenge [ 12 ].…”

In recent years, graphene has found its use in numerous industrial applications due to its unique properties. While its impermeable and conductive nature can replace currently used anticorrosive toxic pigments in coating systems, due to its large strength to weight ratio, graphene can be an important component as a next-generation additive for automotive, aerospace and construction applications. The current bottlenecks in using graphene and graphene oxide and other two-dimensional materials are the availability of cost-effective, high-quality materials and their effective incorporation (functionalization and dispersion) into the product matrices. On overcoming these factors, graphene may attract significant demands in terms of volume consumption. Graphene can be produced on industrial scales and through cost-effective top-down routes such as chemical, electrochemical and/or high-pressure mechanical exfoliation. Graphene, depending on end applications, can be chemically tuned and modified via functionalization so that easy incorporation into product matrices is possible. This paper discusses different production methods and their impact on the quality of graphene produced in terms of energy input. Graphene with an average thickness below five layers was produced by both methods with varied defects. However, a higher yield of graphene with a lower number of layers was produced via the high-pressure exfoliation route. This article is part of a discussion meeting issue ‘A cracking approach to inventing new tough materials: fracture stranger than friction’.
