Special Issue Information

Dear Colleagues,

Nanoparticles, as opposed to their larger counterparts, exhibit unique properties due to their high surface area and nanoscale size. Though they have been extensively researched over the past decade, they still present challenges and can be promising candidates for a wide scope of applications. The synthesis of nanoparticles or nanocomposites with tailor-made properties is a gold standard in scientific research.

This Special Issue in Molecules aims to bring together research papers on the synthesis of nanoparticles, as well as their applications. Presenting a broad scope, this Special Issue welcomes full papers and review articles on organic or inorganic nanoparticle synthesis, stabilization and functionalization, multifunctional nanocomposites and their applications in a wide range of fields.

High-performance water-based inkjet inks are critical for advancing inkjet printing technology. The performance of water-based inkjet inks depends largely on the dispersion stability of organic pigments. This imposes higher demands on the performance of polymeric dispersants. However, the relatively weak interaction between polymeric dispersants and organic pigments limits their performance in water-based inkjet inks. Consequently, it is crucial to seek dispersants that exhibit stronger interactions with pigments, alongside high performance, and universality. In this work, five types of polymeric nanoparticles (PNPs) with anion-π groups were synthesized via a simple emulsion polymerization method. Compared to traditional polymeric dispersants, anion-π type PNPs exhibited significant advantages including low viscosity, solvent resistance, and high temperature resistance. Stronger interactions, including salt-bridge hydrogen bondings (H-bonds) and π–π interactions, between these PNPs and different types of organic pigments were demonstrated by FTIR, UV-Vis, and XPS spectral tests. In particular, PNPs-5, bearing -PhSO3 groups, exhibited the strongest interaction with the organic pigments. The water-based inkjet inks, formulated with PNPs-5 serving as a dispersant, exhibited remarkable dispersion stability and outstanding weatherability. This work rationally constructs a strategy for preparing universally applicable polymeric dispersants to enhance the dispersion of pigments in water-based inkjet inks, thereby presenting a broader perspective for applications in the field of inkjet printing.
