Abstract: A transmittance-variable layer and a transmittance-variable device including the same are disclosed herein. In some embodiments, a transmittance-variable device includes a polarization layer and a transmittance-variable layer disposed on the polarization layer, wherein the transmittance-variable layer includes a first base layer disposed on the polarization layer and a spacer fixed on a surface of the first base layer opposite to the polarization layer, and a second base layer facing the first base layer and spaced apart from the first base layer by the first spacer, wherein the first spacer maintains a gap between the first and second base layers, and a first light modulating material disposed in the gap.

Abstract: Disclosed is a novel method of preparing a secondary amine compound using a microflow reactor. According to the method, a primary amine compound and a halide compound are allowed to react with each other in the microflow reactor, such that the production of a tertiary amine compound or an ammonium salt is minimized, whereby the secondary amine compound is efficiently prepared.
