Effect of N-cetylpyridinium chloride in adsorption of graphene oxide onto polyester

• The graphene oxide particles do not adhere to polyester.
• This behavior can be reversed, modified surface charge of the fiber.
• Adhesion of graphene oxide has been achieved by treating the fiber with NCPCL.
• The adhesion of graphene on the fiber is optimal at pH = 3.

Coating fabrics with particles of different types is of great interest for their applications in very different fields. For example, fabrics covered with conductive materials receive special attention for their smart applications. Graphene material is a good candidate for this owing to its properties of high flexibility, thermal and chemical stability, and high thermal and electrical conductivity. As a derivative of graphene, graphene oxide (GO) has also become an attractive material that has been investigated widely. In this work, we examine the adsorption properties of Graphene onto synthetic polyester (PET) fibers. These adsorption processes depend on the surface properties of both materials. We present a complete surface characterization, including surface free energy and zeta potential measurements. We then describe an experimental investigation of the adsorption process of GO onto PET and how the process is improved when the PET is pretreated with surfactants substances.
