High ink absorption performance of inkjet printing based on SiO ₂ @Al ₁₃ core-shell composites

The increasing growth of the inkjet market makes the inkjet printing more necessary. A composite material based on core-shell structure has been developed and applied to prepare inkjet printing layer. In this contribution, the ink printing record layers based on SiO ₂ @Al ₁₃ core-shell composite was elaborated. The prepared core-shell composite materials were characterized by X-ray photoelectron spectroscopy (XPS), zeta potential, X-ray diffraction (XRD), scanning electron microscopy (SEM). The results proved the presence of electrostatic adsorption between SiO ₂ molecules and Al ₁₃ molecules with the formation of the well-dispersed system. In addition, based on the adsorption and the liquid permeability analysis, SiO ₂ @Al ₁₃ ink printing record layer achieved a relatively high ink uptake (2.5 gmm ⁻¹ ) and permeability (87%), respectively. The smoothness and glossiness of SiO ₂ @Al ₁₃ record layers were higher than SiO ₂ record layers. The core-shell structure facilitated the dispersion of the silica, thereby improved its ink absorption performance and made the clear printed image. Thus, the proposed procedure based on SiO ₂ @Al ₁₃ core-shell structure of dye particles could be applied as a promising strategy for inkjet printing.
