“…Poly(vinyl butyral) (PVB), composed of vinyl butyral, vinyl alcohol, and vinyl acetate segments (Figure a), finds a broad spectrum of applications encompassing robust bonding, optical clarity, and adhesive properties in laminated glass for automotive and solar cell, − as well as its role as a coalescing agent in tape casting and 3D printing inks. − The growth in the automotive glass market is anticipated to propel the demand for laminated glass over the forecast period. Recent advancements have unveiled pioneering uses of PVB and its analogues in diverse fields, including a substrate for soft lithography, a refractive layer for optical devices, pervaporation membranes, biodegradable packaging, , radiative cooling membranes, , and even biomedical engineering, exemplified by optical imaging, skin patches, and keratoprostheses . The demands of these applications necessitate PVB products characterized by robust mechanical properties, strong glass adhesion, favorable solubility, and heightened thermal stability.…”
