开发了一种基于铂络合物的单组分压敏涂料（PC-PSP）。这种可喷涂、快速响应的 PSP 表现出响应时间短、鲁棒性高和压力灵敏度高，随后被应用于压力分布的时间分辨测量。所提出的 PC-PSP 的粘合剂是通过将聚（甲基丙烯酸异丁酯）与二氧化钛（TiO2）颗粒以不同比例混合来制备的。研究了颗粒质量含量对 PSP 性能的影响，包括响应时间、压力灵敏度和发光强度。还研究了对 TiO2 颗粒进行亲水和疏水表面处理对粘合剂层的结构和机械强度的影响。使用疏水性TiO2 制备了具有实际应用的PC-PSP。这种材料应用简单，对基材具有很强的附着力和快速响应。疏水性 TiO2 颗粒的极性与用于制造粘合剂的甲苯的极性相似，因此即使颗粒质量含量增加到 97 wt%，它们也能保持致密的粘合剂结构，因此具有更好的粘合性。从响应时间和粗糙度的角度来看，93 wt% 的颗粒质量含量提供了高性能。
A single-component pressure-sensitive paint (PC-PSP) based on a platinum complex was developed. This sprayable, fast-response PSP exhibited a short-response time, high robustness, and high-pressure sensitivity and was subsequently applied to the time-resolved measurement of pressure distribution. The binder of the proposed PC-PSP was prepared by mixing poly(isobutyl methacrylate) with titanium dioxide (TiO2) particles in various proportions. The effects of a particle mass content on the properties of the PSP, including response time, pressure sensitivity, and luminescent intensity, were investigated. The effects of applying hydrophilic and hydrophobic surface treatments to the TiO2particles on the structure and mechanical robustness of the binder layer were also studied. A PC-PSP having practical applications was produced using hydrophobic TiO2. This material is straightforward to apply and shows strong adhesion to the substrate together with a fast response. Hydrophobic TiO2particles, which had a polarity similar to that of the toluene used to make the binder, provided better adhesion because they could maintain a dense binder structure even when the particle mass content was increased to 97 wt%. A particle mass content of 93 wt% gave a high performance from the point of view of response time and roughness.
