采用Pickering乳液聚合法制备了双酚A（BPA）分子印迹聚合物（MIP），并将其封装在聚合物微胶囊中。在聚合过程中，BPA除了作为模板分子外，还为MIP颗粒在聚合物微胶囊中的包封提供了机会。其关键在于过饱和BPA的成核以及共聚物与正十六烷的相分离。扫描电镜（SEM）表征结果表明，MIP粒子平均粒径约为2 μm，完全包覆在聚合物微胶囊中。利用EDS和SEM等分析手段，详细阐述了其形成过程，并进行了验证.重结合实验表明，该分子印迹聚合物与BPA具有良好的结合特性，结合速度快（30 min内达到结合平衡），结合特异性高（印迹因子为1.96），为BPA的分离纯化和分析提供了潜在的应用前景。
In this work, the molecularly imprinted polymer (MIP) particles for bisphenol A (BPA) were prepared and encapsulated simultaneously in the polymer microcapsule through facile Pickering emulsion polymerization. During polymerization, BPA also offers the opportunity for the encapsulation of MIP particles in the polymer microcapsule except as template molecule. The key point lies in the nucleation of oversaturated BPA and the phase separation between the resulting copolymer and hexadecane. The morphological characterization was performed by SEM and the result indicated that the MIP particles with an average size of 2 μm were perfectly encapsulated in the polymer microcapsule. The formation process was elaborated and verified by the technique of EDS and SEM. Rebinding experiments showed that the MIP possessed excellent binding properties toward BPA, including fast binding rate (reaching binding equilibrium within 30 min) and efficient binding specificity (the imprinting factor of 1.96), which presents a potential application for BPA separation, purification and analysis.
