In this paper, we report the synthesis and characterization of novel coatings based on (3-aminopropyl)-triethoxysilane (AP) mixed with different amounts of glutaraldehyde (GA). The synthesized coatings have been layered on a glass substrate and characterized by optical microscopy and roughness measurements, thermogravimetric analyses and differential scanning calorimetry, contact angle analysis, rheological measurement, and an adhesion test. It was observed that the higher the GA content (up to AP:GA ratio of 0.3), the sooner the crosslinking reaction starts, leading to a coating with increased hydrophobic and adhesion features without compromising the final AP cross-linked network. Hence, the obtained results show the effectiveness of AP modification with GA from the perspective of an application as protective coatings.
在本文中，我们报道了基于（3-氨丙基）-三乙氧基硅烷（AP）与不同量戊二醛（GA）混合的新型涂层的合成与表征。合成的涂层已涂覆在玻璃基板上，并通过光学显微镜和粗糙度测量、热重分析和差示扫描量热法、接触角分析、流变学测量以及附着力测试进行表征。观察到GA含量越高（直至AP:GA比例为0.3），交联反应开始得越早，从而形成具有增强的疏水和附着特性的涂层，而不会损害最终的AP交联网络。因此，从作为保护涂层的应用角度来看，所获得的结果表明了用GA对AP进行改性的有效性。
