Fabrication and characterization of neodymium-macrocycle and its MDOPE composite antibacterial films
This work aims to investigate relative effects of neodymium-macrocycle complex Nd-2f as the antimicrobial agent on the microstructure, thermal stability, and antibacterial activity of Nd-2f/MDOPE (machine direction orientation polyethylene) composite films. Under two different contents, 0.5 wt% and 5.0 wt% Nd-2f/MDOPE composite films are designed and prepared by the extrusion blow molding technology. They are carefully characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). It is shown that the low-content Nd-2f can be uniformly mixed with MDOPE substrate. Compared with the pure MDOPE film, the incorporation of complex Nd-2f will not affect the basic properties of MDOPE but greatly promote its antibacterial activity. When the content of complex Nd-2f is 0.5 wt%, the Nd-2f/MDOPE composite film shows optimal overall performance with excellent thermal stability and antibacterial activity, and it is thus referable for more polyethylene composite antibacterial films with high dispersibility and compatibility.
期刊介绍：
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
