Structure and properties of plasticized polyvinyl butyral‐silica nanocomposite films and test production of laminated glass using films

Abstract

Plasticized polyvinyl butyral (PVB)-silica nanocomposite films were formed by mixing PVB ethanol solution and silica sol, which was prepared from tetraethyl orthosilicate. The nanocomposite films were colorless and transparent even though the content of silica was 70 wt%. The glass transition temperature of PVB in the silica 2.5 wt% nanocomposites was higher by about 108C than that of plasticized PVB. The PVB-silica nanocomposite films were applied as an interlayer for laminated glass. The laminated glass made with the nanocomposite films containing less than 10 wt% silica showed good penetration resistance, not only at room temperature but also at 708C. J.

Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note

“…It was confirmed that the PVB-silica nanocomposite films containing less than 5 wt.% silica were appropriate for use as the interlayer for highperformance laminated glass. 16 Obradovic ´et al reported that the impregnation of p-aramid fabrics with PVB/ethanol solution which contained 30 wt.% AMEO silane modified silica nanoparticles produced improved mechanical properties in the body armor. 17 Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation, growth and collapse of bubbles.…”
