Abstract
Provided herein is a modified Polyhedral Oligomeric Silsesquioxane (POSS) compound and a light valve device using the modified POSS compound. The modified POSS compound is a liquid compound synthesized via hydroxyl condensation among a component I, a component II and a component III; wherein the component I is a POSS monomer having at least one hydroxyl; the component II is a dihydroxyl-terminated crosslinkable monomer or oligomer; the component III is a dihydroxyl-terminated non-crosslinkable monomer or oligomer. The light valve device being capable of electronically changing its light transmittance is made by sandwiching a light control layer between two transparent electroconductive substrate layers. The light control layer is made by a solid polymeric matrix containing modified POSS compound. The solid polymeric matrix is formed by solidifying of a modified POSS compound under ultraviolet irradiation or heating.
