Development of Microparticle Implanted PVDF-HF Polymer Coating on Building Material for Daytime Radiative Cooling

“…Since changes in climate all over the world are currently a major issue, clean cooling techniques are urgently needed. Because passive radiative cooling specifically matches the need for cooling all day, especially during the midday, it can continuously produce passive cooling effects for a variety of applications, such as city buildings [7][8][9], photovoltaic applications [10][11][12], power generation [13][14][15], and painted cooling surfaces [16][17][18][19], adding to the considerable saving of energy. In the past, radiative cooling was applied with the help of various types of radiative coolers which had stark high emissivity and a solar reflection capability with multilayer and complex materials [20][21][22][23], meta materials [4,24], polymerized coatings [23][24][25][26], and porous forms [27][28][29][30][31].…”

Colorful Superhydrophobic Composite Coating for Efficient Passive Radiation Cooling

“…Passive radiant cooling (PRC) is a green and ideal solution, where nighttime radiant cooling materials can achieve environmental cooling through their own high emissivity . Passive daytime radiative cooling (PDRC), on the other hand, achieves passive cooling by reflecting sunlight and radiating excess heat into space at transparent windows in the atmosphere. , The research of PDRC materials in radiative cooling is relatively more difficult because it needs to achieve high reflectivity (>90%) in the solar spectrum band . Therefore, the development of cheap and efficient PDRC materials is particularly important to the global warming trend.…”
