Poly(N-isopropylacrylamide) (PNIPAM) is an organic environment-sensitive material, which can be combined with photocatalysts to control the photocatalytic process. Herein, rodlike environment-sensitive Bi2O3 (PNIPAM/Bi2O3) was prepared by a novel one-step continuous microwave method. This new method is efficient and convenient. The as-prepared PNIPAM/Bi2O3 was very sensitive to temperature and pH, and the degradation rate in the environment of 25 °C and pH = 9 was 3.87 times than that in the environment of 45 °C and pH = 5. While Bi2O3 is under the above various environmental conditions, its degradation rate did not change obviously. More interestingly, the introduction of PNIPAM and one-step continuous microwave method was beneficial to the transformation of Bi2O3 from no specific shape to rodlike morphology without changing its crystal structure. This work not only developed a new one-step continuous microwave synthesis method, but also opened up new ideas for the controllability requirements of materials in special environment.

涂覆有温度敏感聚合物的 Bi2O3 棒的连续微波合成

聚（N-异丙基丙烯酰胺）（PNIPAM）是一种有机环境敏感材料，可与光催化剂结合控制光催化过程。在这里，棒状环境敏感 Bi2O3（PNIPAM/Bi2O3）是通过一种新型的一步连续微波方法制备的。这种新方法既高效又方便。制备的 PNIPAM/Bi2O3 对温度和 pH 值非常敏感，在 25°C 和 pH=9 环境下的降解率是 45°C 和 pH=5 环境下的 3.87 倍。而 Bi2O3 是在上述各种环境条件下，其降解率没有明显变化。更有趣的是，PNIPAM 和一步连续微波法的引入有利于 Bi2O3 从无特定形状转变为棒状形态而不改变其晶体结构。
