Abstract

The enhanced infrared shielding function of antimony tin oxide (ATO)-doped polymer-dispersed liquid crystal (PDLC) film enables its use for smart windows, because it can switch between transparent and scattered states, which can protect people's privacy. When PDLC film is used for a building's doors and windows or external walls, we hope that it can have a higher infrared shielding capability, in order to reduce the indoor temperature affected by solar irradiation, so as to reduce the energy consumption caused by refrigeration equipment. However, the infrared shielding capability of the existing PDLC is far from sufficient. In this work, modified ATO nanoparticles of different sizes were introduced into the PDLC system to improve its infrared shielding capability. It was found that when the ATO particle size is 20 nm and the doping content is 0.6 wt%, the modified PDLC sample provides optimal infrared shielding function while maintaining excellent electro-optical properties.

摘要

掺锑锡氧化物（ATO）的聚合物分散液晶（PDLC）薄膜增强的红外屏蔽功能使其可用于智能窗户，因为它可以在透明和散射状态之间切换，从而保护人们的隐私。当PDLC薄膜用于建筑物的门窗或外墙时，我们希望它能具有更高的红外屏蔽能力，以降低受太阳辐射影响的室内温度，从而减少制冷设备造成的能源消耗。然而，现有PDLC的红外屏蔽能力远远不够。在这项工作中，将不同尺寸的改性ATO纳米颗粒引入PDLC体系以提高其红外屏蔽能力。发现当ATO粒径为20nm且掺杂含量为0.6wt%时，改性PDLC样品在保持优异电光性能的同时提供了最佳的红外屏蔽功能。
