Ganoderma Lucidum-Modified Clay Epoxy Coating: Investigation of Thermal, Mechanical, Anticorrosion, and Antimicrobial Properties
Herein, firstly, sodium montmorillonite (Na+-MMT) was modified with Ganoderma lucidum (GL), and then the anti-corrosion properties of new nanoparticles (GL-MMT) were evaluated. For this purpose, GL-MMT was added to epoxy (EP), and their nanocomposite was prepared. GL-MMT was evaluated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). Polarization and salt spray tests showed that GL‑MMT improved corrosion resistance. The hydrophobic nature of GL-MMT caused the hydrophobic properties to be observed in nanocomposites so that the EP/3% GL-MMT showed a contact angle of 73°. Also, the results of thermogravimetric (TGA) analysis, adhesion strength, and tensile test showed that GL‑MMT improves the properties of the coating. This enhanced in properties is due to the uniform distribution of GL-MMT in the matrix and also the polymer chains are easily able to penetrate into the MMT galleries. Moreover, the antimicrobial results showed that the coatings containing GL-MMT are inhibitory and killing against Staphylococcus epidermidis and Streptococcus pyogenes.
期刊介绍：
