基于一种仿生方法制备钛酸钾晶须包复聚丙烯织物的太阳能热屏蔽性能
Abstract(#br)Inspired by the special whisker-shaped hairs from the Saharan silver ants (SSant), we fabricated a bionic solar heat shielding fabric by coating prismatic potassium titanate whiskers (PTW) with the binder of polyurethane (PU) and polydimethylsiloxane (PDMS) on the polypropylene (PP) fabric. The test results show that the bionic PTW coated fabric can reflect nearly 90% of the solar irradiance, thus effectively reducing the received radiant power. The solar shielding ability of the fabricated fabric is positively correlated with the density of the coated PTW.
