In recent years, functionalized photopolymer systems capable of holographic recording are in great demand due to their potential use in the development of holographic sensors. This work presents a newly developed N-isopropylacrylamide (NIPA)-based photopolymer for holographic recording in reflection and transmission modes. The optimized composition of the material is found to reach refractive index modulation of up to 5×10 and 1.6×10 after recording in transmission and reflection mode, respectively. In addition to fulfilling the requirements for holographic recording materials, the NIPA-based photopolymer is sensitive to temperature and has lower toxicity than acrylamide-based photopolymers. Possible application of the NIPA-based photopolymer in the development of a holographic temperature sensor is discussed.
近年来，由于能够用于全息传感器的开发，能够进行全息记录的功能化光聚合物系统需求很大。这项工作展示了一种新开发的基于N-异丙基丙烯酰胺（NIPA）的光聚合物，用于反射和透射模式下的全息记录。发现该材料的优化组成在透射和反射模式下记录后，分别达到高达5×10和1.6×10的折射率调制。除了满足全息记录材料的要求外，基于NIPA的光聚合物对温度敏感，并且比基于丙烯酰胺的光聚合物毒性更低。讨论了基于NIPA的光聚合物在全息温度传感器开发中的可能应用。
