“…Therefore, we determined the molecular structure of PVB and its aggregate structure by using gel permeation chromatography (GPC), 1 H nuclear magnetic resonance spectroscopy ( 1 H NMR), and X-ray diffraction (XRD) (Figure S5). The glass transition temperature ( T g ) of PVB was estimated at 72 °C (Figure S6), agreeing well with those reported in other literatures. − T g is the temperature at which the polymer segment starts to move, which is greatly affected by the length of the side chain. In precedent literature, the VIPS process is routinely constrained to the “hard” polymers with glass transition temperatures ( T g ) much higher than that of PVB.…”

Daytime passive radiative cooling has emerged as an energy-saving cooling technique. However, market penetration of current daytime passive radiative cooling-related membranes is still miniscule due to deficiencies in scalability, recyclability, and robustness. This work successfully addresses these issues by concurrently imparting the following features in a designed polymeric cooler: (1) cost-effective and recyclable raw materials that highlight the sustainability; ( 2) scalable yet exquisite structureengineering strategy to afford superb light scattering performance;(3) malleable under facile conditions to fit complex surface conformably. Specifically, our cooling membrane is solely composed of a mass chemical, polyvinyl butyral, which forms a supramolecular network with the polymer−air interface as light scattering sites and −C−O−C− bonds as infrared emitters. The structure of the polyvinyl butyral membrane is exquisitely organized via kinetical arrest of network-forming phase separation. The spatial size, contrast, and distribution of phase domains can be finely manipulated via tuning the composition routes and depth of phase separation. The optimized membrane demonstrates all-day and all-climate cooling with a 7.3 °C subambient cooling and 62 W/m 2 cooling power. In addition to this superb cooling performance, this membrane uniquely affords a collective of multiple features, such as cost effectiveness, recyclability, and hydrophobicity.

“…3c that in air, due to the generation of oxidation products such as peroxides and carbonyl compounds, there are obvious exothermic peaks on the DSC curve. According to the literature, [66][67][68] the possible thermal degradation process of PVB in air is described as follows: the rst process between 200-380 °C is dominated by oxidation, and the DSC curve shows obvious exothermic phenomenon. There is a small endothermic peak between 400-450 °C, which may be due to the pyrolysis of oxidation products.…”

“…[ 26 ] The minimal mass loss can be primarily ascribed to butyric acid obtained via pyrolysis of the dissociatively unreacted butyraldehyde or polyvinyl alcohol in the PVB host, which is manifested as an intense peak (1700 cm −1 ) that corresponded to the CO bond in the carboxyl group. [ 43 ] Additionally, the PVB‐SPE foil exhibited relatively high structural stability up to 150 °C without any notable PVB‐pyrolysis‐induced mass loss; this could help the foil withstand the extreme environmental temperature of 80 °C during long‐term ECD service and a process temperature of 130 °C during ECD lamination. [ 11 ] Furthermore, differential scanning calorimetry (DSC) of the BK samples indicated that the glass transition temperature of each sample was ≈ −60 °C (Figure S4, Supporting Information).…”

Polyvinyl butyral (PVB) is a well-established polymer interlayer material that has been used in laminated safety glass panels for over 80 years. However, its intrinsically poor ionic conductivity (σ) severely restricts its widespread application as a solid polymer electrolyte (SPE) for laminated WO 3 -NiO electrochromic devices (ECDs). Here, a new strategy for significantly improving the σ of PVB via a cross-linking reaction with 3-glycidoxypropyltrimethoxysilane (KH560) is presented. The cross-linked PVB-SPE with 10 wt.% KH560 exhibits the highest room-temperature σ value among the investigated samples (1.51 × 10 −4 S cm −1 ), which is also higher than that of previously reported PVBbased SPEs (10 −5 -10 −7 S cm −1 ). Additionally, the prepared SPE exhibits comprehensive optical, mechanical, and thermal performances, including a high visible transmittance (>91%), relatively high adhesive strength (2.13 MPa), and superior thermal stability (up to 150 °C). Laminated WO 3 -NiO ECDs with dimensions of 5 × 5 cm 2 and 20 × 20 cm 2 , fabricated by leveraging the aforementioned properties of the electrolyte, operate stably at temperatures ranging from −20 to 80 °C, underscoring the potential of the PVB-SPE for realizing commercially viable large-area ECDs.
