We report the successful fabrication of photoresponsive Janus particles (JPs) composed of a methacrylate-based azo polymer (PAZO-ADMA) and poly(methyl methacrylate) (PMMA). The JPs are obtained through microphase separation in a confined volume of the dispersed droplets, which incorporates the azo polymer and PMMA into one single particle in a core-compartmentalized manner. It is observed that several unique types of symmetry-breaking deformations are induced upon irradiation with a linearly polarized laser beam at 488 nm. The JPs with such properties are valuable for fundamental understanding and smart photofabrication in micrometer scale.
我们报道了由基于甲基丙烯酸酯的偶氮聚合物（PAZO - ADMA）和聚甲基丙烯酸甲酯（PMMA）组成的光响应性Janus粒子（JPs）的成功制备。这些JPs是通过在分散液滴的有限体积内进行微相分离获得的，该过程以核分隔的方式将偶氮聚合物和PMMA整合到单个粒子中。观察到在488 nm的线偏振激光束照射下会诱导出几种独特类型的对称破缺变形。具有此类特性的JPs对于微米尺度的基础理解和智能光制造具有重要价值。
