In this study, light-induced phase separation phenomena were studied by using photochemical reactions to drive a polymer mixture from the one-phase into the unstable region on the phase diagram. The competition between the phase separation and the reaction was investigated by using laser scanning confocal microscope. The following results were obtained.:1) Measurements of elastic deformation in photo-reactive multicomponent polymers by using Mach-Zehnder Interferometry.2) Developments of Computer-Assisted Irradiation (CAI) method for designing polymers with an arbitrary distribution of characteristic length scales in the micrometers range.3) Designing multiphase polymer materials with hierarchical morphology by using irradiation with a time delay.4) Synthesis of interpenetrating polymer networks (IPNs) with spatially graded morphology and an arbitrary distribution of characteristic length scales.With the above-mentioned results, we are able to conclude that multiphase polymer materials with a variety of morphologies can be controlled and designed by using photochemical reactions

在这项研究中，光诱导相分离现象进行了研究，通过使用光化学反应驱动的聚合物混合物从单相到相图上的不稳定区域。利用激光扫描共聚焦显微镜研究了相分离与反应之间的竞争。获得了以下结果：1)本论文的主要内容包括：1）利用马赫-曾德尔干涉仪测量光反应性多组分聚合物的弹性变形; 2）利用计算机辅助辐射（CAI）设计具有微米级任意分布特征长度尺度的聚合物; 3）利用延时辐射设计具有分级结构的多相聚合物材料; 4）互穿聚合物网络（IPNs）的合成具有空间梯度形态和任意分布的特征长度尺度的多相聚合物材料。根据上述结果，我们可以得出结论，具有多种形态的多相聚合物材料可以通过光化学反应来控制和设计
