Graphene-based multilayers: Critical evaluation of materials assembly techniques

Printed graphene films with positive temperature coefficient of resistivity

“…Graphene is becoming increasingly popular as a result of its wide range of possible applications such as field effect transistors, sensors, transparent conductive films and supercapacitors [1]. This flexible material has very high electrical conductivity even at room temperature because of its zero bandgap where both electron and hole are involved in charged carriers [2]; the presence of pi (π) electrons in the above and below the graphene flat sheet and their hexagonal lattice structures make the charge carriers mobility to be high [3] [4].…”

Written‐in Conductive Patterns on Robust Graphene Oxide Biopaper by Electrochemical Microstamping

“…[5][6][7][8][9][10][11][12][13] Very limited options for inducing electrical conductivities and long-term stability under wet conditions are the most critical issues for further developments. [14][15][16][17][18][19][20][21] The epoxide, hydroxy, carbonyl, and carboxy groups of graphene oxide enable aqueous processibility and enhance interfacial interactions and cross-linking (Supporting Information, Figure S1).…”

A Green Method for Graphite Exfoliation Using High-Energy Ball Milling

“…The single units named graphenes have attracted considerable attention, because of their excellent mechanical, chemical, thermal, electrical properties and low thermal expansion coefficient [1]. The strong covalent (sp 2 ) bonds in this unique honeycomb structure of graphene and their atomic scale thickness impart them with these unusual properties [2]. Taking advantage of the weakness of these interactions, it is possible to insert ions, atoms or molecules between the layers in order to obtain graphenes from graphite.…”
