Investigation of water-based interior wall coatings containing epoxy resin quaternary ammonium salts with antibacterial properties

The objective of this study was to develop water-based interior wall coatings with antimicrobial properties. Epoxy resin quaternary ammonium salts were synthesized and characterized using FTIR and ¹H NMR spectroscopy. Various compositions of water-based interior coating materials were prepared. The antimicrobial activity of the materials was determined using the inhibition zone method. Thermal stability of samples was evaluated through TGA; while, contact angles were measured to assess hydrophobicity. The resulting water-based interior coating materials exhibited exceptional antimicrobial, thermal and mechanical properties, making them suitable as antibacterial top coatings in diverse industries.
