摘要：以异氰酸丙基三乙氧基硅烷、2-氨基噻唑和咪唑为主要原料，合成了(2-噻唑脲基)丙基三乙氧基硅烷（TUP）
和咪唑酰氨基丙基三乙氧基硅烷（IAP）两种唑硅烷偶联剂，再分别以其为主成膜剂，采用浸涂法在铜箔表面固
化成膜制备了有机金属涂层，并与棕化膜和甲基三乙氧基硅烷（KH132）、3-巯丙基三乙氧基硅烷（KH580）有
机涂层进行了对比。利用 FTIR、SEM、AFM、接触角测量仪对涂层进行了表征。对涂层的防腐性能进行了测定，
并分析了压合后铜面/环氧树脂层间的附着力。结果表明，TUP 和 IAP 均成功接枝到铜基材料表面，形成了一层
相对平整光滑且致密均匀的有机保护膜。TUP 含量（以无水乙醇和水总质量为基准，下同）为 3%形成的有机
金属涂层平整性较好，算术平均粗糙度和均方根粗糙度均<21 nm，疏水性较优，水接触角高达 142°±1°，耐腐蚀
性较强，缓蚀效率可达 99.2%，耐盐雾可达 14 d，压合后铜/树脂层间剥离强度为 5.97 N/cm，能满足印制电路内
层板附着力的要求。

Abstract:Two azole silane coupling agents, (2-thiazolyl)propyltriethoxysilane (TUP) and
imidazolamidepropyltriethoxysilane (IAP) were synthesized from 3-isocyanatopropyltriethoxysilane and
2-aminothiazole and imidazole. Organometallic coatings were then prepared by dipping method on the
copper foil surface using TUP and IAP as then main film-forming agents, and further compared with brown
oxidation film and organic coatings containing methyltriethoxysilane and 3-mercaptopropyltriethoxysilane
respectively. The coatings obtained were characterized by FTIR, SEM, AFM and contact angle
measurement, followed by evaluation on its corrosion resistance as well as the interfacial adhesion between
copper foil and epoxy resin of the laminate. The results indicated that both TUP and IAP were successfully
grafted onto copper surface, and provided relatively smooth and compact organic protective coatings. The
organometallic coating containing 3% TUP (based on the total mass of ethanol and water) exhibited
excellent smoothness and optimal hydrophobicity, with both the arithmetic and root mean square roughness
<21 nm and the water contact angle up to 142°±1°. Furthermore, the corrosion inhibition efficiency could
reach 99.2% and salt spray resistance was up to 14 d, revealing good corrosion resistance. In addition, the
peel strength of copper/resin laminates achieved 5.97 N/cm, which meets the interfacial adhesion
