“…In addition, side effects like high fabrication cost and temperature non-uniformity appear with too thick coatings. 35,36 Moreover, near-ideal broadband emission can also be achieved by a dual-layer structure in other prevalent PDRC polymers (Fig. S12 †).…”

“…Human activities, primarily, fossil fuel burning, boosts the levels of the heat-trapping greenhouse gases in the earth’s atmosphere. The ever-increasing power consumption has raised the global demand for energy and has also resulted in other environmental problems. − Developing environmentally friendly, energy-efficient cooling technologies has become increasingly important as part of efforts to meet the ever-increasing energy demand, such as reducing greenhouse gas emissions, combating climate change, reducing thermal pollution, and addressing energy and economic poverty …”

Passive radiative cooling is a spontaneous pattern of reflecting sunlight and radiating heat into the cold outer space through transparent atmosphere windows. In this work, an ordered-porous-array polymethyl methacrylate (OPA-PMMA) film with the properties of excellent radiative cooling is designed and studied. An ultra-high emissivity of 98.4% in the mid-infrared region (3–25 μm) and a good solar reflectance of 85% in the ultraviolet and near-infrared solar spectra (0.2–2.5 μm) were achieved. The surface temperature of the OPA-PMMA film is 16 °C lower than that of the smooth-surface PMMA films and is 8.6 °C lower than that of the commercial white paint in the outdoor test. The structure of the OPA plays an important role in improving solar reflectivity and emissivity. The films are fabricated using a one-step low-cost process that can be applied for large-scale production. It is vital for promoting radiative cooling as a viable energy technology for buildings, fabric, or equipment that need a cooling environment.
