Title:
POLYMER GEL COMPOSITION, ITS MANUFACTURING METHOD AND OPTICAL ELEMENT USING POLYMER GEL COMPOSITION
Document Type and Number:
Japanese Patent JP2004285203
Kind Code:
A
Abstract:
To provide an optical element which largely changes the total light transmittance, has a small haze value and is highly transparent.
The polymer gel composition comprises a polymer gel continuous phase, a polymer gel particle dispersed in the polymer gel continuous phase which solely causes volume changes by stimulus, and a liquid contained in the polymer gel continuous phase and in the polymer gel particle, where the polymer gel particle contains a dimming material, and the polymer gel continuous phase and the polymer gel particle form an interpenetrating network structure. The optical element comprises the polymer gel composition sandwiched between a pair of substrates and end parts of the substrates are sealed.
