Poly p-aminobenzoic acid has been synthesized by chemical oxidation method. The inhibitive effect of poly p-aminobenzoic acid on iron in 1 mol/L HCl solution was investigated by polarization and electrochemical impedance spectroscopy and compared with that of monomer p-aminobenzoic acid. The effectiveness of poly p-aminobenzoic acid is very high in comparison with that of monomer. The results show that both cathodic and anodic processes were suppressed by p-aminobenzoic acid and poly p-aminobenzoic acid of iron dissolution in 1 mol/L HCl by their adsorption on the iron surface. The inhibition efficiency of both p-aminobenzoic acid and poly p-aminobenzoic acid were found to increase with the inhibitor concentrations. Ultraviolet (UV) reflectance studies of the iron surface after exposure to inhibitor acid show that poly p-aminobenzoic acid is strongly adsorbed on iron surface.

以微波结晶法制备的碳酸根型镁铝水滑石（LDHs）为前体,对氨基苯甲酸为客体,由水热法、离子交换法、焙烧复原法三种方法组装合成了对氨基苯甲酸插层镁铝水滑石复合材料。并用XRD、FTIR、TG-DSC、SEM等对其结构进行表征。结果表明：各种方法均能合成相应的插层水滑石层柱材料,层间距分别扩大为0.81 nm、0.79 nm、1.45 nm。三种合成材料的紫外吸收强弱与对氨基苯甲酸插层水滑石分子后的层间距大小有关。该研究指出对氨基苯甲酸插层水滑石作为一种紫外吸收层柱材料在化妆品领域具有应用潜力。
