Triptycene based microporous hypercrosslinked polymer with amino functionality for selective CO2 capture

Schematic illustration of reflective and heat insulation coatings for passive cooling.AbstractReflective and heat insulation coatings are new types of materials coated on constructions. However, their applications are limited by the undesired insulation effect resulting from the poor reflectance in the solar spectrum of the coating film. In this study, a reflective and heat insulation coating is successfully developed by combining titanium dioxide@polyacrylate (TiO2@PA) hybrid latex with a core?shell structure and an insulation filler of bionic potassium titanate whisker (PTW). The TiO2 nanoparticles are distributed homogeneously in the polymer matrix due to the polymer?encapsulated TiO2 structure, achieving a total solar reflectance (TSR) of 71.0%. Notably, the as?prepared reflective and heat insulation coating films exhibit excellent TSR of 86.0% enabled by TiO2@PA latex and PTW, attributed to the synergistic combination of TiO2@PA and PTW with high TSR. The temperature inside the room coated with the reflective and insulation coatings on the roof is 16.6°C lower than that of the uncoated one, while 20?wt% PTW is introduced into the coating formulation. The resulting reflective and heat insulation coatings are attractive for the fields of passive cooling such as building energy conservation, automotive body, and so on, endowing people with a comfortable life, especially in the hot summer.
