Abstract

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.

灵芝改性粘土环氧涂层：热、机械、防腐和抗菌性能的研究

摘要

本文首先用灵芝（GL）对钠蒙脱石（Na ⁺ -MMT）进行改性，然后评价新型纳米颗粒（GL-MMT）的防腐性能。为此，将GL-MMT添加到环氧树脂（EP）中，制备了它们的纳米复合材料。通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）对GL-MMT进行了评估。极化和盐雾测试表明 GL‑MMT 提高了耐腐蚀性。 GL-MMT 的疏水性导致在纳米复合材料中观察到疏水性，因此 EP/3% GL-MMT 显示出 73° 的接触角。此外，热重（TGA）分析、附着强度和拉伸测试的结果表明，GL-MMT 改善了涂层的性能。这种性能的增强是由于 GL-MMT 在基质中的均匀分布，而且聚合物链很容易渗透到 MMT 通道中。此外，抗菌结果表明，含有GL-MMT的涂层对表皮葡萄球菌和化脓性链球菌具有抑制和杀灭作用。
