Chapter 1. Introduction

Abstract
Graphene and related two-dimensional (2D) materials have attracted considerable research interest across a wide range of application fields due to their unique characteristics. However, significant barriers still remain in the large-scale and low-cost fabrication of devices based on these materials. A widely explored route to accomplishing this is in the formulation of 2D material functional inks for use with existing printing technologies that have been traditionally used for graphics printing. In this chapter, we provide an introduction to the key topics that will be introduced later in the book and give an overview of the current and future economic and technological landscape of 2D materials and their potential applications in the context of printing.

Chapter 2. Structures, Properties and Applications of 2D Materials

Abstract
Early scientific investigations into graphene date back to the 1950s. The interest in graphene intensified when Konstantin Novosolev and Andre Geim were awarded the Nobel prize in physics for ‘groundbreaking experiments regarding the two-dimensional material graphene’. Since then, other two-dimensional (2D) materials have (re)gained increasing research interest. The most studied 2D materials to date include transition metal dichalcogenides (TMDs), black phosphorus (BP), hexagonal boron nitride (h-BN) and transition metal carbides and/or carbonitrides (MXenes). This chapter introduces these key material groups, and provides a review of the current understanding of their structures and properties. In particular, this chapter will focus on the (opto)electronic properties of the individual 2D materials and their potential applications.

Chapter 3. 2D Material Production Methods

Abstract
The widespread use of printing of 2D materials in their relevant applications is highly dependent on the cost and scalability of their methods of production. This chapter serves as an introduction to the key methods for 2D material production and characterisation. Methods such as chemical vapour deposition, plasma cracking of hydrocarbons, intercalation, chemical exfoliation and liquid phase exfoliation are described and their relative merits are discussed. Particular emphasis is given to the 2D materials relevant to ink production. The latter half of the chapter discusses commonly used processing steps and characterisation methods for the 2D materials and their respective roles in qualifying and quantifying the material produced.

Chapter 4. 2D Ink Design

Abstract
The use of two-dimensional (2D) materials in low-cost, high-throughput printing as a scalable production method relies heavily on its successful incorporation into printable ink systems. However, industrial scale production of 2D material printing inks has proven to be a significant challenge. This chapter begins with a brief history of inks and progresses to the basic ink formulations and the techniques used in traditional printing technologies. This chapter also discusses ink properties, processing techniques and optimisation of formulation parameters using methods such as Design of Experiments (DOE), and useful characterisation techniques when formulating 2D material inks. Finally, the chapter covers ink–substrate interaction and optimisation strategies for ink formulation.

Chapter 5. Printing Technologies

Abstract
Printing is a mature, ubiquitous industry and is used extensively across the globe for mass producing a wide range of decorative products; from books and magazines through to packaging, advertising posters and even automobile dials. This chapter will provide an in-depth description of four of the most widely used methods: inkjet, screen, gravure and flexographic printing. In addition, 3D printing as a deposition method will also be discussed. The chapter includes an overview of the vital parameters of note for each of the different printing methods and gives a quantitative description of the different interactions within individual printing systems. Finally, generic starting formulations of 2D material inks unique to each printing method are also provided.

Chapter 6. Applications of Printed 2D Materials

Abstract
The primary goal of this book is to comprehensively review 2D materials that have gained research interest and present the use of printing as a low-cost, high-throughput method of exploiting 2D materials in mass produced devices and components. This chapter covers the existing demonstrations of printed 2D materials in a wide variety of devices and summarises their current status. In addition, this chapter also discusses the state-of-the-art literature on the trends and development stages, future technology directions and their likely convergence for next generation of applications, devices and systems.
