NOVELTY - The utility model claims a nanometer macromolecular film material based on modified by. The multifunctional graphene film material prepared by the dehumidifying assembly, and indoor isothermal dehumidifying device, through indoor isothermal dehumidifying method using said device, solves the problem that the dehumidifier dehumidifying discontinuous, condensed water is generated, the working cavity is easy to be eroded mildew changeable and frequent switching valve, additional heating isothermal unit and so on. The utility model can effectively solve the continuous isothermal dehumidifying problem, no condensation water is produced, with good system reliability, dehumidifying precision is high, the device is easy to maintain.
