使用电化学测试站对腰果酚基环氧树脂复合涂层耐腐蚀性能进行表征。制备步骤：环氧化腰果酚与一定量的氧化石墨烯填料混合并搅拌均匀，将混合物与双酚A型环氧树脂复配，用四面制备器刮涂在Q235钢板上，25℃下固化12小时达到表干，60℃下固化完全得到厚度约为100μm的涂层干膜。将涂层在3.5wt%的盐水中浸泡60天，在10^5-10^-2 Hz的频率范围内，20mV的振幅下测试涂层的交流阻抗。

Characterization of the corrosion resistance of cashew phenolic based epoxy resin composite coatings using an electrochemical testing station. Preparation steps: Mix epoxidized cashew nut phenol with a certain amount of graphene oxide filler and stir evenly. Mix the mixture with bisphenol A epoxy resin, and scrape it onto Q235 steel plate using a four sided preparator. Cure at 25 ℃ for 12 hours to reach surface dryness. Cure completely at 60 ℃ to obtain a thickness of about 100 μ Coating dry film of m. Soak the coating in 3.5wt% saline water for 60 day, and test the AC impedance of the coating at a frequency range of 10 ^ 5-10 ^ -2 Hz and an amplitude of 20mV.
