TY - JOUR TI - Antifouling and anticorrosion performance of the composite coating made of tetrabromobisphenol-A epoxy and polyaniline nanowires AU - Wu, Changhao AU - Wang, Jixiao AU - Song, Shuangshuang AU - Wang, Zhi AU - Zhao, Song T2 - Progress in Organic Coatings AB - Tetrabromobisphenol-A epoxy (TBEP), based on its hydrophobicity and antibacterial activity, is suitable to prepare top coating. Meanwhile, bisphenol-A epoxy (EP), based on its strong adhesion strength with metals, is a commonly material to prepare primer coating. Polyaniline (PANI) nanowires, which can facilitate the formation of passivation layer, is usually used as additive to reinforce the corrosion resistance of coatings. Herein, the composite coating composed of EP primer coating with 2 wt% PANI nanowires and TBEP top coating with 2 wt% PANI nanowires was assembled and characterized. Because the hydrophobic and antibiotic bromine atoms existed in TBEP, the composite coating exhibited low water absorption (0.32 wt%) and high antibacterial rate (over 93.17 %) compared with pure EP coating. Moreover, the composite coating had good adhesion with metals (dry: 5.65 MPa, wet: 4.07 MPa) and excellent anticorrosion properties (|Z|0.01 Hz > 1011 ohms·cm2 after 70 days immersion) in comparison to the composite coating without PANI nanowires, since the PANI nanowires provide multifunctional behaviors such as passivation, barrier, etc. This work might give a new perspective to prepare efficient antifouling and anticorrosion coating via reasonably combine the advantages of different functional materials.
