Total heat exchange membrane with antibacterial and mildewproof functions and total heat exchanger

The invention discloses a total heat exchange membrane with antibacterial and mildewproof functions and a total heat exchanger. The total heat exchange membrane includes a functional layer, which comprises a high polymer and an antimicrobial additive; and an optional support layer, on which the functional layer is compounded. The invention also discloses a preparation method of the total heat exchange membrane and the total heat exchanger making use of the membrane to undergo energy exchange. During long-term use of the total heat exchange membrane and the total heat exchanger to provide fresh air to the indoor, remove foul and harmful air, and recover heating ventilation air conditioning energy, growth of bacteria, mildew and other organisms on the total heat exchange membrane can be effectively avoided, the enthalpy exchange efficiency and the temperature exchange efficiency can be improved, and the service life and performance of the to the support layer. The total heat exchanger preparation method of the
