技術說明

本發明提供一種由環境空氣中擷取水滴的裝置，包含一絕緣基板、複數電極膜單元，及一液晶聚合物複合膜，每一個電極膜單元一第一電極及一第二電極，該液晶聚合物複合膜覆蓋該等電極膜單元並包括一與該環境空氣接觸的接觸面及複數個液晶分子，每一個液晶分子具有一親水部分及一疏水部分，藉由施加電壓於該第一電極及該第二電極而產生一電場，而改變該等液晶分子的排列位向，使該接觸面具有親水性，進而使環境空氣中的水氣易於該接觸面凝結而被收集。 This invention provides a device for extracting water droplet from ambient air, including a insulating substrate, a plurality of electrode film units, and a liquid crystal/polymer composite film. Each of the electrode film units includes a first electrode and a second electrode. The liquid crystal/polymer composite film covers the electrode film units and includes a contact surface which exposures to the ambient air and a plurality of liquid crystal molecules. Each of the liquid crystal molecules has a hydrophilic functional group and a hydrophobic moiety. When a voltage is applied between first and second electrodes to generate an electric field, that changing the orientation of these liquid crystal molecules, result in the contact surface.
