摘要

聚醚具有作为冷却剂和润滑剂的明显优势，这通常取决于它们在水中的溶解度。本研究提出了温度相关的近红外光谱来研究聚醚水溶液的溶解度和相变化。采用二维相关谱法建立了温度与近红外光谱之间的关系，确定了团聚度、浊度和温度变化的顺序。结果表明，水和亚甲基的吸收峰蓝移与温度有良好的相关性，这与聚醚和水分子之间氢键的形成和破坏有关。由于氢键的破坏，黏度也与蓝移振幅呈良好的线性相关。水性聚醚润滑剂的相变和成膜机理也为新型润滑剂的开发提供了重要信息。

Analysis of the polyether aqueous solution with temperature dependent NIR spectra

The polyether has distinct advantage of being a coolant and a lubricant, which is often dependent on their solubility in water. In this study, the temperature dependent near-infrared spectroscopy was proposed to investigate the solubility and phase changes of polyether aqueous solution. Two-dimension correlation spectrum was applied to establish the relationship between temperature and NIR spectra, and determine the order of aggregation, turbidity and the temperature changes. The results demonstrated that the absorption peak blueshift of water and methylene exhibit good correlation with the temperature, which is related to the formation and destruction of hydrogen bonding between polyether and water molecules. Due to the destruction of hydrogen bonding, the viscosity also showed a good linear correlation with the amplitude of blueshift. The mechanism of phase change and film-forming of aqueous polyether lubricants also provide important information on development of new types of lubricants.
