Abstract A new series of boric acid (BA) induced cross-linked poly(vinyl alcohol-co-ethylene) (EVOH)/graphene oxide (GO) nanocomposite (EVOH/BA/GO) films are prepared using different amount of GO and BA with respect to EVOH. The EVOH/BA/GO nanocomposites are respectively coated on nylon films and stainless steel substrates by a typical spray coating method, followed by thermal and hydrazine vapor treatment for gas barrier and corrosion studies. The Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analyses confirm the formation of cross-linked nanocomposite through the formation of B–O–C bond. The field emission scanning electron microscopy analysis indicates the formation of homogeneous structure for these nanocomposites. The storage modulus (at 25 °C) and elastic modulus of EVOH/15BA/5GO-coated film with 15% BA and 5% GO are enhanced by 280 and 60%, respectively, in comparison to nylon film. EVOH/15BA/5GO-coated nylon film exhibits dramatic reduction of hydrogen (6.9) and oxygen gas (1.5) transmission rates (cc/m2∙d∙atm) than pure nylon film. In addition, EVOH/15BA/5GO-coated stainless steel shows an ultralow corrosion current (0.294 μA/cm2) and corrosion rate (3.43 × 10−3 mm/year) than steel. A comparative study between EVOH/BA/GO and EVOH/GO is performed to examine the effect of the cross-linker on the different physical properties.

硼酸诱导交联聚（乙烯醇-共聚-乙烯）/氧化石墨烯薄膜的增强气体阻隔和防腐性能

摘要 使用不同量的 GO 和 BA 制备了一系列新的硼酸（BA）诱导交联聚乙烯醇-共聚乙烯（EVOH）/氧化石墨烯（GO）纳米复合材料（EVOH/BA/GO）薄膜。关于 EVOH。EVOH/BA/GO 纳米复合材料通过典型的喷涂方法分别涂覆在尼龙薄膜和不锈钢基材上，然后进行热和肼蒸汽处理以进行气体阻隔和腐蚀研究。傅里叶变换红外光谱和 X 射线光电子能谱分析证实了通过形成 B-O-C 键形成交联纳米复合材料。场发射扫描电子显微镜分析表明这些纳米复合材料形成了均匀结构。与尼龙薄膜相比，含有 15% BA 和 5% GO 的 EVOH/15BA/5GO 涂层薄膜的储能模量（25°C）和弹性模量分别提高了 280% 和 60%。EVOH/15BA/5GO 涂层尼龙薄膜与纯尼龙薄膜相比，氢气 (6.9) 和氧气 (1.5) 传输率 (cc/m2∙d∙atm) 显着降低。此外，EVOH/15BA/5GO 涂层不锈钢显示出比钢超低的腐蚀电流（0.294 μA/cm2）和腐蚀速率（3.43 × 10−3 mm/年）。进行了 EVOH/BA/GO 和 EVOH/GO 之间的比较研究，以检查交联剂对不同物理性质的影响。此外，EVOH/15BA/5GO 涂层不锈钢显示出比钢超低的腐蚀电流（0.294 μA/cm2）和腐蚀速率（3.43 × 10−3 mm/年）。进行了 EVOH/BA/GO 和 EVOH/GO 之间的比较研究，以检查交联剂对不同物理性质的影响。此外，EVOH/15BA/5GO 涂层不锈钢显示出比钢超低的腐蚀电流（0.294 μA/cm2）和腐蚀速率（3.43 × 10−3 mm/年）。进行了 EVOH/BA/GO 和 EVOH/GO 之间的比较研究，以检查交联剂对不同物理性质的影响。
