Abstract The study aims to highlight the outline of icon conditions. One of the main reasons for deterioration and degradation of the icons is the humidity. Evaluation the icons state after the humidity aging has been recorded through observing the physio-chemical changes and transforming the prescription of painting from subjective to objective matter with analytical data. The study could be described in the six elements: design six modern icons, conduct artificial ageing of five icons in the 85% relative humidity level at different aging times, analyze the icons with an array of analytical techniques, collect the whole data, analyze of the results, and conclude the results with recommendations about the appropriate conditions to store and display of the icons. The study has included various analytical methods: digital photography, attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), differential thermal analysis (DTA), colorimetric measurement, inferential statistical method (Friedman ANOVA) and computational modeling method (MO-G PM6). The results showed that the hydration effect of the humidity induced conformational changes within the painting materials with change of the vibrational frequencies of the infrared spectra. The thermal analyses revealed that the aged materials had high thermal stability with decomposition at higher temperatures. The kinetic and thermodynamic calculations determined low reaction rate constant, low entropy, positive signs of enthalpy and Gibbs free energy of the products. There was an alteration of the aesthetic features with color change of the paintings and Friedman ANOVA proved that there was a difference in the color changes along the time intervals. PM6 semiemperical method showed that the increase of water molecules of humidity could lead to increase the reactivity of the compounds with the surrounding system and deterioration of the paint film.

结合分析方法评估湿度老化对图标模型涂装材料的影响

摘要 本研究旨在突出图标条件的轮廓。图标变质和退化的主要原因之一是湿度。通过观察生理化学变化，并用分析数据将绘画处方由主观到客观物质，评估记录湿度老化后的图标状态。该研究可以用六个要素来描述：设计六个现代图标，在不同老化时间的85％相对湿度水平下对五个图标进行人工老化，使用一系列分析技术分析图标，收集整体数据，分析结果，并通过有关存储和显示图标的适当条件的建议来总结结果。该研究包括各种分析方法：数码摄影、衰减全反射傅里叶变换红外光谱 (ATR-FTIR)、热重分析 (TGA)、差热分析 (DTA)、比色测量、推理统计方法 (Friedman ANOVA) 和计算建模方法 (MO-G PM6)。结果表明，随着红外光谱振动频率的变化，湿度引起涂料内部构象变化的水化作用。热分析表明，老化材料具有较高的热稳定性，在较高温度下会分解。动力学和热力学计算确定了低反应速率常数、低熵、焓的正符号和产物的吉布斯自由能。随着绘画的颜色变化，审美特征发生了变化，弗里德曼方差分析证明，随着时间的推移，颜色变化存在差异。PM6 半经验法表明，湿度水分子的增加会导致化合物与周围体系的反应性增加和漆膜劣化。
