Abstract

Purpose The paper aims to design the optimum formulation of the nano-titanium dioxide (TiO2) hydrophilic coating system using the synthetic polypropylene glycol (PPG), which can create the reflection and absorption property. Design/methodology/approach TiO2 nanoparticles are used as fillers, and PPG has been blended at the proper ratio of 1PPG: 0.2TiO2. The prepared resin has been applied onto the glass substrate at different numbers of glass immersions during the dip-coating fabrication process. One-time glass immersion is labeled as T1 coating, two-time glass immersion is labeled as T2 coating and three-time glass immersion is labeled as T3 coating. All the prepared coating systems were left dry at ambient temperature. Findings T3 coating showed the lowest reading of WCA value at 40.50°, due to higher surface energy at 61.73 mN/m. The T3 coating also shows the greatest absorbance property among the prepared coating systems among the prepared coating. In terms of reflectance property, the T2 coating system has great reflectance in UV region and near-infrared region, which is 16.47% and 2.77 and 2.73%, respectively. The T2 coating also has great optical transmission about 75.00% at the visible region. Research limitations/implications The development of thermal insulation coating by studying the relationship between convection heat and reflectance at different wavelengths of incident light. Practical implications The developed coating shows high potential for glass window application. Originality/value The application of the hydrophilic coating on light absorption, reflectance and transmission at different wavelengths.

亲水透明纳米二氧化钛涂层的透射和反射研究

目的设计以合成聚丙烯乙二醇(PPG)为原料制备纳米二氧化钛(TiO2)亲水性涂料体系的最佳配方，使其具有反射和吸收性能。设计/方法/途径采用TiO2纳米粒子作为填料，将PPG以1PPG: 0.2TiO2的适当比例混合。在所制备的树脂在浸渍涂层制造过程中以不同的玻璃浸渍次数涂在玻璃基板上。一次性玻璃浸泡标记为T1涂层，两次玻璃浸泡标记为T2涂层，三次玻璃浸泡标记为T3涂层。所有制备的涂层体系在室温下保持干燥。结果T3涂层的WCA值在40.50°处最低，为61.73 mN/m。在制备的涂层体系中，T3涂层也表现出最大的吸光性能。在反射率方面，T2涂层体系在紫外区和近红外区具有较大的反射率，分别为16.47%、2.77%和2.73%。T2涂层在可见光区也有很高的透光率，约为75.00%。研究局限/启示通过研究不同波长入射光对流热与反射率的关系来发展隔热涂层。实际意义所研制的涂层在玻璃窗上具有很大的应用潜力。亲水性涂层在不同波长光的吸收、反射和透射方面的应用
