Zinc oxide sol-containing diallylmethyl alkyl quaternary ammonium salt synthesized by sol–gel process: characterization and properties

Abstract

Zinc oxide sols-containing quaternary ammonium bromide compounds, including diallylmethyl dodecyl/tetradecyl/ hexadecyl/octadecyl ammonium bromide, were synthesized from zinc acetate and quaternary ammonium bromide compounds via sol-gel process. Effects of alkyl chain length and double allyl of quaternary ammonium salts on the stability of the sols were investigated. The sols were characterized by X-ray diffraction. Morphologies of the sols were observed with transmission electron microscopy. The various zinc oxide sols were applied to cotton fabrics. Antibacterial activity, UV resistance, and mechanical properties of the treated fabrics were tested. It was verified that alkyl chain length and double allyl of quaternary ammonium salts had effects on the stability of the sols. Application results showed that UV resistance and antibacterial rate of the fabric finished by zinc oxide sols-containing quaternary ammonium salts first increased and then decreased with an increase in the alkyl chain length of quaternary ammonium salts. However, the sols had negative effects on breaking strength and elongation at break of the fabric.

New Functionalized Macroparticles for Environmentally Sustainable Biofilm Control in Water Systems

“…BAC gathered the attention of the scientific community because of its physical–chemical characteristics [ 26 ] and its mechanisms of interaction with bacteria [ 27 ], later discussed in the Results and Discussion section of the present paper. Several studies regarding the immobilization of QAC compounds in nanostructured material were published [ 22 ], including the functionalization of metal oxide nanoparticles [ 28 , 29 ]. However, none of those cases include the functionalization of macroscopic metal oxide pellets.…”

Fabrication of Core–Shell Nanohybrid-Structured Hydrogel Sensors with Desirable Mechanical and Antibacterial Properties by Quaternary Ammonium Ionic Liquids with Different Chain Lengths

“…45,46 Dimethylammonium ethyl methacrylate (DM) is amine basic; the molecule contains a tertiary amino group, an ester group, and an unsaturated double bond, and acid can produce salt and chloromethane and other reactions to produce quaternary ammonium ionic liquids (DM x ). 47,48 Taking inspiration from the alkylamines in the natural antibacterial purple daisy, we synthesized a series of antibacterial hydrogels based on DM x (X = 2, 6, 12, and 16) with different chain lengths. The effect of the length of the hydrophobic alkyl group on the antimicrobial activity of DM x and on the mechanical properties of the aniline spheretoughened hydrogel as well as the effect of the aniline sphere content on the conductivity of the hydrogel were investigated in more detail.…”

“…Fortunately, the emergence of antimicrobial materials offers great hope for solving the problem of infection risk. − For example, cationic polyelectrolyte brushes grafted from bacterial cellulose (BC) nanofibers were introduced into a polydopamine/polyacrylamide hydrogel by Yang et al, and the hydrogel showed less inflammatory response and a faster healing rate in wound healing in rats in vivo . The preparation methods for the binding of antimicrobial agents to hydrogels mainly include physical binding (direct encapsulation, solubilization and diffusion, carrier encapsulation) and chemical binding (formation of chemical bonds between hydrogels with inherent antimicrobial activity). , Amines are widely present in the biological world, with very important physiological and biological activities; for example, alkaloids, nucleic acids, antibiotics, and proteins are amine derivatives, and most of the drugs are amines or amine derivatives, so mastering the nature and synthesis of amines is the basis of the study of these complex natural products and the better maintenance of human health. , Dimethylammonium ethyl methacrylate (DM) is amine basic; the molecule contains a tertiary amino group, an ester group, and an unsaturated double bond, and acid can produce salt and chloromethane and other reactions to produce quaternary ammonium ionic liquids (DM x ). , Taking inspiration from the alkylamines in the natural antibacterial purple daisy, we synthesized a series of antibacterial hydrogels based on DM x ( X = 2, 6, 12, and 16) with different chain lengths.

Development of Antibacterial and Hemostatic PCL/Zein/ZnO‐Quaternary Ammonium Salts NPs Composite Mats as Wound Dressings

“…As long-acting antibacterial agents, quaternary ammonium compounds have been used to modify ZnO NPs to enhance their antibacterial activity. [28] Mascia et al prepared ZnO NPs in situ within polyethyleneimine (PEI) matrix following blended them with zein to produce zeinmodified fibers by electrospinning, and the antibacterial activity and mechanical property of the composite zein fibers were significantly improved. [29] Hui et al incorporated quaternary ammonium chitooligosaccharides into ZnO/palygorskite nanocomposites which showed good synergistic antibacterial effect.…”
