摘要 |
<p>The invention relates to a multifunctional optical sensor, having at least 2 areas which independently react to different input parameters, the sensor comprising a substrate and a polymeric layer comprising polymerized liquid crystal monomers having an ordered morphology, wherein the color, the reflectivity or the birefringence of the sensor changes due to a change of the morphology, wherein said change of the morphology is caused by physical contact with a chemical agent such as a gas or liquid a change of temperature, or passage of time. The invention also relates to a process for the preparation of the sensor and for the use of a film comprising a single substrate, a layer having a cholesteric liquid crystalline structure for application in labels for packaging of perishable goods, food, fine chemicals, bio-medical materials.</p> |
