光栅结构对智能凝胶光栅传感器检测性能的影响规律
Effects of grating structures on detection performances of smart hydrogel grating sensors
摘要
Abstract
A thorough investigation on the quantitative impacts of grating geometric parameters on the detection performance of smart hydrogel grating sensors is an essential prerequisite for rationally designing their geometric structures.In this study,the N-isopropylacrylamide(NIPAM)monomers and tetra-arm polyethylene glycol acrylamide(tetra-arm-PEGAAm)regarded as large-molecule cross-linking agent were used to synthetize temperature-responsive smart hydrogel grating sensor,and three various heights of hydrogel gratings were fabricated by microcontact printing to explore their influences on the detection performances.The results indicated that,the fabricated hydrogel gratings exhibited highly regular and ordered surface microstructures under both dry and wet conditions,and always possessing with high transparency and real-time reversible response properties.Besides,as the height of hydrogel grating increased,the diffraction signals of smart hydrogel grating sensors could be obviously enhanced under the same temperature stimulus,thus exhibiting more pronounced changes in diffraction efficiency and signal amplification.These findings in this study provided valuable guidance for the rational design of the geometric structures of smart hydrogel grating sensors.关键词
