本文提出了一种制备中空聚（N-异丙基丙烯酰胺）（PNIPAM）-银纳米复合微球的方法。在该方法中，首先通过一锅法“自去除”工艺合成热敏PNIPAM空心球，然后将其用作Ag +离子的配位和原位还原的载体。结果表明，PNIPAM-Ag纳米复合空心球仍具有典型的热敏性，且具有良好的催化活性，且催化活性随温度的变化具有5个阶段。
This article presents a strategy for the fabrication of hollow poly(N-isopropylacrylamide) (PNIPAM)-Ag nanocomposite spheres. In this approach, the thermosensitive PNIPAM hollow spheres were first synthesized via a one-pot "self-removing" process and then used as supporters for the coordination and in situ reduction of Ag + ions. The results show that these hollow PNIPAM-Ag nanocomposite spheres still have typical thermal sensitivity, and importantly, these spheres have very good and controllable catalytic activity with five stages of variation versus temperature.
