    摘要:

    聚合物材料的力学性能与其固化过程密切相关,因此需要全场监测手段为其提供丰富、可靠的实验依据。受限于固化行为的不可逆性,现有监测技术无法对单向固化过程进行重复测量以获取多维全面的监测信息。针对该问题,提出了一种融合荧光成像和层析干涉的多模态全场固化监测方法,借助荧光数字图像相关技术和相位敏感光学相干层析成像技术的高灵敏全场测量优势,同步实现对聚合物表面形貌和内部截面固化过程的全场应变估计。为验证该方法有效性,搭建了一套多模态监测系统,分别建立近紫外荧光激发、蓝色荧光散斑成像、近红外层析成像3个并行监测通道。之后通过背光方式激发光固化聚合物材料CharmFil Flow并对其固化过程进行全面监测。在利用该系统采集荧光散斑和干涉光谱的过程中,首先通过对荧光散斑进行图像相关性计算,实现了表面x-y平面内x、y方向上的全场应变监测;然后通过对层析成像结果进行图像相关性计算,实现了内部x-z平面内的x轴横向全场应变监测;最后通过对层析成像结果进行差分相位分析,实现了内部x-z平面内的z轴纵向全场应变监测。此外,在实验过程中还通过对多个维度下的时间量程收缩形变进行定量表征,验证了多模态固化监测结果的一致性。因此,所提方法可有效地同时实现聚合物固化过程中表面和内部的多模态全场固化监测,为深入聚合物固化动力学、优化固化参数等提供一种全面可靠的测量手段。

    Abstract:

    The mechanical properties of polymer materials are intricately linked to their curing process. This relationship highlights the need for full-field monitoring techniques to provide rich and reliable experimental data. Due to the irreversible nature of curing, current methods cannot repeatedly measure a unidirectional curing process to get comprehensive, multi-dimensional information. To overcome this, we propose a novel multimodal full-field curing monitoring method that combines fluorescence imaging and tomographic interferometry. This approach leverages the high-sensitivity, full-field measurement capabilities of fluorescence digital image correlation and phase-sensitive optical coherence tomography to simultaneously estimate full-field strain on both the polymer's surface and internal cross-section during curing. We validated this by building a multimodal monitoring system with parallel channels for near-ultraviolet fluorescence excitation, blue fluorescence speckle imaging, and near-infrared tomographic imaging. Using backside illumination, we comprehensively monitored the curing of CharmFil Flow. During data acquisition, we calculated image correlations from fluorescence speckle to monitor full-field surface strain in the x-y plane. We then applied image correlation to tomographic results for internal transverse full-field strain along the x-direction in the x-z plane and used differential phase analysis for internal z-axis longitudinal full-field strain in the same plane. The consistency of our multimodal curing monitoring results was further confirmed by quantitatively characterizing time-domain shrinkage deformation across multiple dimensions. In essence, our method effectively achieves simultaneous multimodal full-field monitoring of both surface and internal polymer curing, offering a comprehensive and reliable measurement tool for in-depth studies of polymer curing dynamics and optimization of curing parameters.
