NOVELTY - This new utility model belongs to curtain technology area, one can control temperature of curtain, comprising guide temperature substrate and wherein vanadium dioxide coating is set with the guide temperature substrate one side. The beneficial effect of the utility model breaks through the traditional curtain on new, vanadium dioxide coating is set with guide heat on substrate surface, when need rising indoor temperature, using vanadium dioxide turning to sunny side, using vanadium dioxide coating heat absorbing effect (visible light and infrared light and can through coating) for heat transfer to heat guide substrate, heat guide substrate again for heat transfer to indoor, the indoor temperature can make regulating, when not needed rising temperature can directly using vanadium dioxide turned to back side is positive.
