Abstract
An article includes a substrate with a surface, and a coating disposed over the surface. The coating includes a binder material and a plurality of porous polymer particles having pores with a variety of pore sizes including a first set of pores having a first average pore size d1 in the range 0.3≤d1/λ1≤0.7, wherein λ1 is a wavelength in the range of 250-400 nm, a second set of pores having a second average pore size d2 in the range 0.3≤d2/λ2≤0.7, wherein λ2 is a wavelength in the range of 400-700 nm, and a third set of pores having a third average pore size d3 in the range 0.3≤d3/λ3≤0.7, wherein λ3 is a wavelength in the range of 700-3000 nm, wherein the porous polymer particles have a shell which is impermeable to a liquid.
