摘要： Polyaniline has a wide application in the field of corrosion protection, the poor solubility of polyaniline limited its application as a corrosion inhibitor. Water-soluble cellulose–polyaniline composites was synthesized by chemical oxidation polymerization in a mild way without other inorganic or organic acids added. Corrosion inhibition performance of composites was evaluated for Q235 steel corrosion in 1 M HCl corrosive solution using weight loss and electrochemical measurements at various concentrations. The results show that cellulose doped polyaniline composites exhibit good inhibition properties and the remarkable increase in inhibition efficiency, i.e., 94.24% is achieved while the maximum concentration of the experiment is 1000 ppm. The composites in corrosive solution suppress the cathodic hydrogen evolution reactions and anodic metal dissolution of the substrate. Adsorption of the inhibitor on the steel surface follows a Langmuir adsorption isotherm.（聚苯胺在防腐领域有着广泛的应用，聚苯胺溶解性差限制了其作为缓蚀剂的应用。在不添加其他无机酸或有机酸的情况下，采用温和的化学氧化聚合方法合成了水溶性纤维素-聚苯胺复合材料。采用重量损失法和电化学测量法对Q235钢在1M盐酸腐蚀溶液中的缓蚀性能进行了评价。结果表明，纤维素掺杂聚苯胺复合材料具有良好的缓蚀性能，当实验的最大浓度为1000ppm时，缓蚀效率显著提高，达到94.24%。复合材料在腐蚀性溶液中抑制了基体的阴极析氢反应和阳极金属溶解。抑制剂在钢表面的吸附遵循Langmuir吸附等温线。）
创新点：1、反应条件温和，聚苯胺合成过程中不添加其他无机酸或有机酸。
2、合成所用的掺杂原料来源广泛，可选择多种无害无毒物质。
