Abstract: A polymer aerogel has polymerizable monomers and crosslinkers, wherein at least one of the monomers or at least one of the crosslinkers has a refractive index of less than 1.5, and the polymer aerogel has a visible transmittance of at least 20%/3 mm, a haze of 50%/3 mm or lower, and a porosity of at least 10%. A method of producing an aerogel includes dissolving precursors into a solvent, wherein the precursors include monomers, crosslinkers, a controlling agent and an initiator to form a precursor solution, wherein at least one of the monomers or at least one of the crosslinkers has a refractive index of 1.5 or lower, polymerizing the precursor solution to form a gel polymer, and removing the solvent from the gel polymer to produce an aerogel polymer.

Abstract: Disclosed herein are implementations of a radiative cooling formulation, an apparatus including a substrate coated with the radiative cooling formulation, and a method of applying a coating of the radiative cooling formulation to an object. In one implementation, a radiative cooling formulation includes a binder which includes a first polymer and a second polymer that are practically water insoluble and are substantially non-absorbing to light having wavelengths in a solar spectrum. The radiative cooling formulation further includes a solar reflector material embedded in the binder.

Abstract: A sensor has a transparent polymer aerogel, and sensing materials dispersed into the transparent, polymer aerogel, where the sensing materials change color in response to environmental conditions. A method of forming a sensor includes providing a substrate, forming a polymer aerogel layer on the substrate, and infusing the polymer aerogel layer with sensing molecules.
