Abstract

This study employed monolayer graphene oxide to modify the surface of perylene pigments C.I. Pigment Red 179 and C.I. Pigment Red 149 via ball milling in a solvent medium, aiming to improve their performance. The composition and structure of modified pigments were determined and characterized with scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), and their fluorescence properties, specific surface area, thermal stability, particle size distribution, color characteristics, water contact angle, and dispersion stability were assessed. In addition, the adsorption structure and electronic properties of graphene oxide on the surface of perylene red pigment molecules, as well as the interaction behavior of perylene red pigment molecules with graphene oxide, were explained by density functional theory (DFT) calculations. Results showed non-covalent interactions between perylene red pigments and monolayer graphene oxide, leading to a more concentrated particle size distribution, enhanced yellow hue, and increased color strength to 104.3 %–117.1 %. The interaction distance between the two components was approximately 3.6 Å.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
