1. A method for manufacturing a radiative cooling textile, comprising the steps of:
a) providing an organic solution containing a polymer;
b) adding a metal oxide into the organic solution to form a suspension;
c) electrospinning the suspension on a substrate to form an electrospun fabric of nanofibers; and
d) performing a heat-pressing treatment to the electrospun fabric thereby subjecting nanofibers in the electrospun fabric to inter-fiber fusion and bonding;
wherein an average diameter of the nanofibers is about 0.45 μm, and the thickness of the radiative cooling textile is about 85 μm.
