With the aim to prepare antibacterial styrene‐acrylic emulsion, a series of bis‐quaternary ammonium salt‐containing mono‐methacrylates MEQABr‐x(x = 12, 14, 16) were synthesized as polymerizable antibacterial agents via two steps. The chemical structures of MEQABr‐x(x = 12, 14, 16) were confirmed by proton nuclear magnetic resonance (1H‐NMR) and Fourier transform infrared (FTIR). The Minimum inhibitory concentration (MIC), Minimum bactericidal concentration (MBC), and Critical micelle moncentration (CMC) results showed that MEQABr‐x(x = 12, 14, 16) had antibacterial properties and surface properties which was influenced by its alkyl chain length. The antibacterial emulsion (SAQx‐n) was synthesized by emulsion polymerization of styrene (St), butyl acrylate (BA), acrylic acid (AA) and MEQABr‐x(x = 12, 14, 16). The structures of its films (SAQx‐n‐F) were characterized by attenuated total reflectance‐FTIR. The effects of MEQABr‐14 content or alkyl chain length of MEQABr‐x(x = 12, 14, 16) on emulsion and its films were investigated in the aspect of particle sizes, pencil hardness, adhesive force grade, thermal stabilities, surface morphology, particle morphology, and so forth. The films (SAQx‐9‐F) with 9 wt% content of MEQABr‐x(x = 12, 14, 16) showed the nearly 100% antibacterial rate against Escherichia coli and Staphylococcus aureus, indicating its potential to be used as antibacterial coating.

“…It could be seen that fluorinefree acrylate coating had many surface defects, such as pores and large area block defects in Figure 3a. That was resulted from the large amount of emulsifier and the moisture content of the acrylate emulsion during the coating formation [22]. With an evaporation treatment, the polymer particles were densely packed and coalesced into a continuous coating.…”

A core-shell fluorine modified polyacrylate hybrid latex was successfully prepared by seed emulsion polymerization. The emulsion was characterized by fourier transform infrared spectroscopy and transmission electron microscopy. After the emulsion was prepared on the surface of stainless steel, the surface of the coating was observed. The heat resistance of the coating was analyzed by thermogravimetry, and the corrosion process of the coating was studied by electrochemical experiments. The results showed that the crosslinking degree and the heat resistance of the coating has been improved. The corrosion potential was increased from -0.46 V to -0.17 V and the current density was reduced from 2.50×10 -6 A/cm -2 to 5.54×10 -8 A/cm -2 compared with the unmodified coating. The improvement of its anti-corrosion performance is mainly due to the improvement of the shielding effect and surface hydrophobicity. Due to its special core-shell structure, the addition of fluoromonomer to achieve this effect is only 2.36%.

A novel, water-soluble N-halamine precursor based on s-triazine (2-(aminoethanesulfonic sodium salt)-4-(4-imino-2,2,6,6- tetramethylpiperidine)-6-monochloro-1,3,5-triazine, ATDT) was synthesized and characterized by FT-IR and 1H-NMR. The cotton fabrics were functionalized with ATDT through the traditional pad-dry-cure method, and optimal conditions were successfully obtained by measuring the active chlorine content. The antibacterial activity of ATDT-coated cotton fabrics was investigated against Staphylococcus aureus and Escherichia coli O157:H7. As a result, 100% of bacteria could be inactivated within a brief contact time. Cell viability was also determined and the results showed that ATDT-modified cotton fabrics had good cytocompatibility to mammalian cells. In addition, the preparation process had little effect on the tensile strength and whiteness of cotton fabrics, although the air permeability showed a slight decrease. The chlorinated ATDT-coated fabrics showed excellent stability against storage and washing.
