Blue-colored aluminum pigments with double layer structure [email protected]₂@(CuPc-SO₃)₂Ba were prepared by a two-step process of surface modification. The aluminum pigments were firstly encapsulated using tetraethoxysilane (TEOS) and silane coupling agents as precursors. A kind of water-soluble organic dye CuPc-SO₃H was immobilized onto the surface of [email protected]₂ by liquid-phase deposition. SEM, FTIR, XRD and XPS were used to characterize the surface morphology and chemical structure of the [email protected]₂@(CuPc-SO₃)₂Ba pigments. The effect of different silane coupling agents and optimum conditions on the two-step surface modification were studied. The corrosion results showed that the coupling agent with long alkyl chain could significantly improve corrosion resistance of aluminum pigments. Chromatism analysis indicated that the glossiness of [email protected]₂@(CuPc-SO₃)₂Ba pigments decreased slightly and showed angle-dependent optical effect.

通过两步表面改性制备了双层结构[电子邮件保护] ₂ @（CuPc-SO ₃）₂ Ba的蓝色铝颜料。首先使用四乙氧基硅烷（TEOS）和硅烷偶联剂作为前体封装铝颜料。通过液相沉积将一种水溶性有机染料CuPc-SO ₃ H固定在[email protected] ₂的表面上。SEM，FTIR，XRD和XPS表征了[email protected] ₂ @（CuPc-SO ₃）₂的表面形态和化学结构。钡颜料。研究了不同硅烷偶联剂和最佳条件对两步表面改性的影响。腐蚀结果表明，具有长烷基链的偶联剂可以显着提高铝颜料的耐腐蚀性。色度分析表明，[电子邮件保护的] ₂ @（CuPc-SO ₃）₂ Ba颜料的光泽度略有下降，并表现出与角度有关的光学效应。
