摘要: 本文利用全息散射方法研究了掺杂纳米粒子丙烯酰胺聚合物的pH值敏感度。观察水处理时全息散射图像的时间变化,并进行了相应的量化分析。为了考察水处理的影响,我们计算了噪声光栅的散射损失。本文将PH值水溶液作为主要影响因素分析聚合物水凝胶的膨胀特性,确定了散射损失和pH值之间的量化关系。实验结果表明全息散射可以作为一种有效的手段分析溶液的性质,本文的聚合物系统可以制作全息传感器,探索周围环境PH值的变化。本文的工作为全息传感器的应用提供了一种新颖的方法。
Abstract: The pH sensitivity of nanoparticles dispersed acrylamide polymer is characterized by using holographic scattering strategy in this paper. Temporal evolution of holographic scattering image is observed under water treatment. The corresponding quantitative analyses are achieved. The scattering losses are measured to explore the effect of water treatment on the parasitic gratings. pH values as primary factors are introduced into the solution to analyze the swelling of polymerhydrogel. The quantitative relations between scattering losses and pH are determined. It is demonstrated that the holographic scattering as an effective analyzing method can be used to characterize the solution properties. The corresponding polymer system can become a sensor to explore the environmental factor. This work can provide a novel strategy for holographic sensing application.
