摘　　要：通过一种科学可行的检测方法对漆膜的渗透性进行研究对饱水漆器文物的形成机理以及对其文物保护填充过程的原理的探索具有十分重要的意义。本研究中漆膜在水中的渗透过程是通过三种天然生漆旋转涂布在铁质基底上形成的漆膜在3.5%氯化钠水溶液中随浸泡时间变化的电化学阻抗谱进行表征。结果表明,样品漆膜电容呈现出随着浸泡时间增加而增大直至达到一个平衡值的变化趋势。同种漆膜的电容值随着漆膜层数增加而减小,而吸水量和耐渗透时间随着漆膜厚度增加而增大。The study on the permeability of lacquer film using a scientific and feasible testing method is significant for exploring the formation mechanism of waterlogged lacquer relics and the principle of their protective filling process.To study the permeability of natural lacquer film in the aqueous solution,the variation of electrochemical impedance spectroscopy(EIS)in a 3.5%NaCl aqueous solution with time,of samples prepared on iron substrates coated with three kinds of natural lacquer was investigated.The result shows that the lacquer film capacitance increased at extended time,until it reached an equilibrium value.The capacitance of each film decreased with the increase of layer number,and the soakage and penetration time increased with the increase of film thickness.
