“…4 Therefore, having plants on the roofs of buildings (i.e., green roofing) and using water-retentive materials in construction can result in cooler buildings through transpiration and evaporation, respectively. 5,6 Most materials used in the exterior walls of buildings are made from porous ceramics. Compared with dense ceramics, porous ceramics not only are more lightweight and highly machinable but also exhibit greater sound absorption, heat insulation, and water retention.…”

“…Roofs and walls receive stronger direct radiation from the sun for longer periods than do other parts of buildings, and approximately 70% of heat gained in top floor rooms comes through roofs and walls . Therefore, having plants on the roofs of buildings (i.e., green roofing) and using water-retentive materials in construction can result in cooler buildings through transpiration and evaporation, respectively. , …”

In this study, a new class of thermosensitive poly(N-isopropylacrylamide)-co-poly(acrylic acid) (P(NIPAAm-co-AAc))-grafted modified silica (msilica) nanocomposites was prepared using a sol−gel technique. The addition of silica to P(NIPAAm-co-AAc) copolymer hydrogel has the potential to open up new applications in the development of thermosensitive building materials by leveraging the favorable thermal characteristics of P(NIPAAm-co-AAc). The silica was prepared using 3-aminopropyltriethoxysilane and 4,4′-azobis(4-cyanovaleric acid) to form the m-silica powder, which increased the adhesion between the organic and inorganic hybrid materials. The P(NIPAAm-co-AAc) copolymer hydrogel was mixed with the m-silica to form the P(NIPAAm-co-AAc)-grafted m-silica nanocomposites. Scanning electron microscopy, X-ray diffraction analysis, thermogravimetric analysis, Fourier-transform infrared spectroscopy, and thermosensitive measurement were conducted to evaluate the structure and water-holding capacity of the nanocomposites. The results indicated that the P(NIPAAm-co-AAc)-grafted m-silica nanocomposites could retain water for more than 300 min at temperatures higher than the lower critical solution temperature. The P(NIPAAm-co-AAc)-grafted m-silica nanocomposites exhibited favorable thermosensitive properties and may therefore be applied in smart architectural coatings.
