Preparation and Antibacterial Activity of ZnO/Palygorskite Nanocomposites Using Different Types of Surfactants Aiping Hui1,2 · Rui Yan1,2 · Bin Mu1,2 · Yuru Kang1,2 · Yanmin Zhou3 · Aiqin Wang1,2 Received: 8 February 2020 / Accepted: 23 May 2020 © Springer Science+Business Media, LLC, part of Springer Nature 2020
Abstract ZnO/palygorskite nanocomposites were facilely synthesized as antibacterial agent by a hydrothermal method using different types of surfactants including sodium dodecyl sulfate, polyvinyl pyrrolidone and cetyltrimethylammonium bromide. The nanocomposites were characterized by Fourier transform infrared spectroscopy, X-ray diffraction field emission scanning electron microscopy, transmission electron microscope, energy dispersive spectrometer, Brunauer–Emmett–Teller analysis and zeta potential. The results showed that the morphologies and antibacterial properties of ZnO/palygorskite nanocomposites could be controlled by changing the types of surfactants. The minimum inhibitory concentration of ZnO/palygorskite nanocomposites prepared with sodium dodecyl sulfate against E. coli was 1.5 mg/mL, while it was 0.5 mg/mL for ZnO/ palygorskite prepared with cetyltrimethylammonium bromide against S. aureus. The experimental results suggested that the ZnO/palygorskite nanocomposites might be served as a potential antibacterial agent in animal feeding.

1 Introduction Widespread overuse of antibiotics on animals has been faulted for creating potentially threat for human beings [1]. There is an urgent need to develop eco-friendly alternative antibacterial agent to reduce the antibiotics use and the increasing health risks [2–4]. Recently, clay minerals have attracted significant interest in the field of antibacterial materials due to their attractive advantages such as nontoxic, ecofriendly and easy modification using the selected organic or inorganic substances with good antibacterial activities and high security [5, 6]. Palygorskite (PAL), a hydrous layer-ribbon magnesium aluminum silicate, is common in many parts of the world. PAL possesses particular rod-like nanostructure, moderate surf
