Highly structured, molecularly imprinted polymer (MIP) networks for copper(II) ion sequestration have been realized using the additive manufacturing technology. Photopolymerizable formulations with acrylic functional monomers and two different porogens (water and methanol) in different ratios were studied to produce emulsions with 50 vol% of the internal phase. The results of morphological characterization indicate that all MIPs have cauliflower-like multiscale structures that change as a function of the solvent combination and fabrication process. X-ray fluorescence microscopy maps presented a layered structure and homogeneous distribution of copper in the printed MIP. Copper(II) ion adsorption-desorption tests were performed on MIPs prepared using a three-dimensional (3D) printing approach and MIPs prepared by bulk polymerization. Results indicate that the 3D printed MIP is able to absorb copper up to ten times more efficiently than the nonprinted one and the printed MIP with 100% water content has the highest imprint recognition.
利用增材制造技术实现了用于螯合铜（II）离子的高度结构化分子印迹聚合物（MIP）网络。研究了含有丙烯酸功能单体和两种不同致孔剂（水和甲醇）不同比例的可光聚合配方，以制备内相体积分数为50%的乳液。形态表征结果表明，所有MIP均具有菜花状多尺度结构，其会随溶剂组合和制备工艺而变化。X射线荧光显微镜图谱显示了印刷MIP中铜的层状结构和均匀分布。对采用三维（3D）打印方法制备的MIP和本体聚合法制备的MIP进行了铜（II）离子吸附-解吸试验。结果表明，3D打印的MIP吸收铜的效率比未打印的MIP高十倍，且水含量为100%的打印MIP具有最高的印迹识别能力。
