In this study, the effect of pure and modified hexagonal boron nitride (h-BN) nanosheet incorporation on the stability, viscosity, and electrochemical behavior of a waterborne emulsion acrylic coating was studied. The functionalization of h-BN nanoplatelets with polyacrylic acid (PAA) plasma polymerization was performed, and the successful surface modification was determined through water dispersion testing, Fourier transform infrared spectroscopy and thermogravimetric analysis, X-ray photoelectron spectroscopy, and also by transmission electronic microscopy. Later, the stability and viscosity properties of emulsion nanostructured acrylic coatings, which were previously prepared by an ultrasound-assisted mixing system, were analyzed using zeta potential and rheometry testing, respectively. The electrochemical behavior was analyzed by electrochemical impedance spectroscopy. The results prove an effective deposition of PAA films on the h-BN surfaces, which enhanced the stability and viscosity acrylic of nanostructured coatings due to the interactions between the h-BN nanoplatelets surface and emulsion acrylic paint and also with the thickener additives. On the other hand, the electrochemical analysis demonstrated a significant increase (two orders of magnitude) in corrosion resistance in the acrylic nanostructured coatings with 1 wt.% of unmodified and modified h-BN nanoplatelets concerning pure acrylic paint due to a barrier protection mechanism of corrosion inhibition. Therefore, the results demonstrate that the surface modification of h-BN by plasma polymerization (green technology) helped to solve the low dispersibility issue of BN nanosheet surfaces in a waterborne polymer matrix to obtained green nanostructured acrylic coatings with the right balance in in-can properties and corrosion inhibition of AISI 304 stainless steel.

改性六方氮化硼纳米粒子对AISI 304不锈钢耐腐蚀纳米结构丙烯酸涂料乳化稳定性，粘度和电化学行为的影响

在这项研究中，研究了纯净和改性六角形氮化硼（h-BN）纳米片的掺入对水性乳液丙烯酸涂料的稳定性，粘度和电化学行为的影响。进行了h-BN纳米片的聚丙烯酸（PAA）等离子体聚合功能化，并通过水分散测试，傅立叶变换红外光谱和热重分析，X射线光电子能谱以及透射电子显微镜确定了成功的表面改性。随后，分别使用zeta电位和流变学测试分析了以前由超声辅助混合系统制备的乳液纳米结构丙烯酸涂料的稳定性和粘度性能。通过电化学阻抗谱分析电化学行为。结果证明，PAA膜可在h-BN表面上有效沉积，这是由于h-BN纳米片表面与乳液丙烯酸涂料以及增稠剂之间的相互作用而增强了纳米结构涂料的丙烯酸稳定性和粘度。另一方面，电化学分析表明，与纯丙烯酸涂料有关的未改性和改性h-BN纳米片的重量百分比为1％，丙烯酸的纳米结构涂层的耐腐蚀性显着提高（两个数量级），这归因于其保护层的机理腐蚀抑制。因此，
