Bifunctional bimetal-POSS films integrating UV-IR shielding and reversible thermochromism

Self-Cleaning Red-Toned Perylene Poly(aryl ether) Film with Superior NIR Reflectance for Passive Radiative Cooling

“…13 The multilayer films usually consist of a thin metal underlayer to achieve high reflectance of the solar radiation in the visible and NIR region. 14 A high emissivity at the atmospheric window (8−13 μm) can be simultaneously obtained by stacking the reflective layer with multilayer absorbers. 15,16 With the development of nanomanufacturing technology, 17 adjustable reflectance and emissivity of materials were achieved by precisely controlling the shape, size, and arrangement of surface micro−nano structures.…”

“…To investigate the conditions of phase separation on the pore formation, a series of P-FPAE solutions with different concentrations (12,14,16,18, and 20 wt %) was prepared. P-FPAE films were obtained under different formation parameters, including the type of nonsolvent bath (water, methyl alcohol, ethanol, isopropanol, and tertiary butanol), the soaking time (1, 5, 10, 15, and 20 min), and the DFPTDA content (1, 2, 3, 4, 5, 6, and 7%) in the polymer.…”

“…The commonly adopted structural design for passive radiative cooling materials can be divided into three categories: multilayered films, metamaterials, and porous structures . The multilayer films usually consist of a thin metal underlayer to achieve high reflectance of the solar radiation in the visible and NIR region . A high emissivity at the atmospheric window (8–13 μm) can be simultaneously obtained by stacking the reflective layer with multilayer absorbers. , With the development of nano-manufacturing technology, adjustable reflectance and emissivity of materials were achieved by precisely controlling the shape, size, and arrangement of surface micro–nano structures. , However, the practical applicability of the above strategies are limited by challenges associated with the use of complex equipment and scaling up. , The high reflectivity can be realized through the mismatch in the refractive indexes of different materials hence scattering the incident wave at the interface, such as between the polymer matrix and the air pockets of a porous polymer.…”

A POSS-Based Metal-Phenolic Network with Coupled Hardness and Softness for Photodynamic-Immunotherapy of Triple-Negative Breast Cancer

“…For example, Yang et al synthesized a thin film material composed mainly of Cr/Cu metal salt and POSS by ambient coordinated self-assembly, which exhibits good reversible thermochromic properties with excellent ultraviolet (UV) and ultraviolet− visible spectrum (UV-vis) and infrared spectroscopy (IR) shielding. 33 He et al reported a POSS-modified Re-based porous organometallic polymer as photocatalysts with an improved catalytic effect and structural stability for the CO 2 RR production of syngas. 34 Inspired by the idea of integrating POSS with metal ions for sensing and catalysis applications, POSS is introduced herein for the construction of biomedical nanoplatforms, i.e., POSS was incorporated not only as a rigid dendritic macromolecular nucleus for Ce6 conjugation via a simple yet efficient click coupling to increase the spacing of Ce6 for compromised aggregation and fluorescence quenching, and enhanced photo properties due to the steric hindrance of POSS.…”

“…Notable examples include Yao’s POSS click-grafted with squaraine and gemcitabine for pancreatic cancer treatment and Wu’s POSS modified with hydrophilic polyethylene glycol (PEG) chains and Rose Bengal for further self-assembly into NPs that can deliver the drug to the cell nucleus. , Another interesting finding is the binding ability of POSS with metal ions to form metal-modified sesquisiloxanes. For example, Yang et al synthesized a thin film material composed mainly of Cr/Cu metal salt and POSS by ambient coordinated self-assembly, which exhibits good reversible thermochromic properties with excellent ultraviolet (UV) and ultraviolet–visible spectrum (UV-vis) and infrared spectroscopy (IR) shielding . He et al reported a POSS-modified Re-based porous organometallic polymer as photocatalysts with an improved catalytic effect and structural stability for the CO 2 RR production of syngas …”
