Electrophoretic deposition of graphene-related materials: A review of the fundamentals

Abstract

The Electrophoretic Deposition (EPD) of graphene-related materials (GRM) is an attractive strategy for a wide range of applications. This review paper provides an overview of the fundamentals and specific technical aspects of this approach, highlighting its advantages and limitations. Since obtaining a stable dispersion of charged particles is a pre-requisite for successful EPD, the strategies for suspending GRM in different media are discussed, along with the resulting influence on the deposited film. Most importantly, the kinetics involved in the EPD of GRMs and the factors that cause deviation from linearity in Hamaker's Law are reviewed. Side reactions often influence both efficiency and the nature of the deposited material; examples include the reduction of graphene oxide (GO) and related materials, as well as the decomposition of the suspension medium at high potentials. The microstructural characteristics of GRM deposits, and their degree of reduction, strongly influence their performance in their intended function. These factors will also determine, to a large extent, the commercial potential of this technique for applications involving GRM, and are therefore discussed here.

Enhancement of interaction of L-929 cells with functionalized graphene via COOH+ ion implantation vs. chemical method

“…And the COOH + /graphene and COOH functionalized graphene show the similar FTIR spectra. The broad absorption at 1750 cm −1 suggested the existence of C=O stretching vibration, confirming the formation of -COOH on the COOH + /graphene and COOH functionalized graphene224. In addition, the COOH + /graphene causes the appearance of absorption band centered at 3400 cm −1 , which is attributed to the O-H stretching bands of hydroxy and carboxylic moieties.…”

Graphene Coating on Copper by Electrophoretic Deposition for Corrosion Prevention

“…These advantages have prompted interest to develop water based graphene oxide coating by EPD. There have been several reports on the use of EPD technique for producing graphene coating for corrosion prevention [31][32][33][34][35][36][37][38]. Although uniform layer of graphene nano-sheet have been deposited via this technique, they have reported wide variation in corrosion prevention.…”

Electrophoretic Coating of Octahedral Molybdenum Metal Clusters for UV/NIR Light Screening

“…The effective application of the EPD process has been extensively studied for the fabrication of traditional ceramic materials for a long time [22,23]. In recent studies, the EPD process has been extended to graphene-related materials [24], nanoscale TiO 2 [25], or medical materials, i.e., antimicrobial applications [26], bond tissue engineering [27], protein identification [28], and bio-implants [29], based on the possible control of the thickness on a nanometer scale.…”
