Novel curtain blade

The invention relates to a novel curtain blade. The novel curtain blade comprises a blade base material, a super-hydrophobic material and a phase change thermal insulation material, wherein the super-hydrophobic material is sprayed on the outer surface of the blade base material, the contact angle between the blade base material and liquid water is increased, the inner surface and a cavity contain phase change heat preservation materials, the super-hydrophobic material can ensure the use durability of the blade material, and the phase-change thermal insulation material adopts a nanotechnology, so that energy can be recovered to the maximum extent, and certain effects on thermal insulation, heat storage and energy conservation are achieved. According to the novel curtain blade, the novel treatment process and method for the inside and outside of the blade base material can prolong the service life of the curtain to the maximum extent, ensure the maximum recycling of energy, and enable the temperature control o
