Anodized-aluminum pressure-sensitive paint (AA-PSP) uses the dipping deposition method to apply a luminophore on a porous anodized-aluminum surface. We study the dipping duration, one of the parameters of the dipping deposition related to the characterization of AA-PSP. The dipping duration was varied from 1 to 100,000 s. The properties characterized are the pressure sensitivity, temperature dependency, and signal level. The maximum pressure sensitivity of 65% is obtained at the dipping duration of 100 s, the minimum temperature dependency is obtained at the duration of 1 s, and the maximum signal level is obtained at the duration of 1,000 s, respectively. Among the characteristics, the dipping duration most influences the signal level. The change in the signal level is a factor of 8.4. By introducing a weight coefficient, an optimum dipping duration can be determined. Among all the dipping parameters, such as the dipping duration, dipping solvent, and luminophore concentration, the pressure sensitivity and signal level are most influenced by the dipping solvent.
阳极氧化铝光致发光压力涂料（AA-PSP）使用浸渍沉积法在多孔阳极氧化铝表面涂覆发光体。我们研究了浸渍时间，这是与 AA-PSP 特性相关的浸渍沉积参数之一。浸渍时间从 1 秒到 100000 秒不等。所表征的性能是压力灵敏度、温度依赖性和信号水平。在浸渍时间为 100 秒时获得最大压力灵敏度为 65%，在浸渍时间为 1 秒时获得最小温度依赖性，在浸渍时间为 1000 秒时获得最大信号水平，分别。在这些特性中，浸渍时间对信号水平的影响最大。信号水平的变化是一个 8.4 的因子。通过引入权重系数，可以确定最佳浸渍时间。在所有浸渍参数中，例如浸渍时间、浸渍溶剂和发光体浓度，压力灵敏度和信号水平受浸渍溶剂的影响最大。
