The invention belongs to the technical field of novel energy materials, and relates to a microwave method for preparing a polypyrrole/metal organic framework nanocomposite material. The microwave method comprises the following steps: uniformly mixing formic acid, nickel salt and polypyrrole, putting the mixture into a domestic microwave oven, and performing a microwave reaction by controlling themass ratio of the polypyrrole to the formic acid to the nickel salt, the microwave power and the microwave heating time to obtain the polypyrrole/metal organic framework nanocomposite material after the reaction. The preparation process is simple and rapid and the production cost is relatively low, so that the polypyrrole/metal organic framework nanocomposite material has a wide application prospect.
