Abstract
(EN)
Provided is a preparation method of a color saturation variable photonic crystal material, comprising: mixing monodispersed microspheres with a solvent, adding adjuncts, and conducting ultrasonic dispersion to form a uniform emulsion; placing the obtained emulsion into a vessel made of a hydrophobic material having low adhesion (F) < 500 μN to water and a water contact angle (CA) ≥ 90°; the solvent evaporates on the gas-liquid interface at 40-100℃ and 5%-95% humidity, causing the monodispersed microspheres in the emulsion to be self-assembled on the gas-liquid interface, thus forming a photonic crystal material of an opal structure. Also provided is a preparation method of a photonic crystal material of an inverse opal structure, comprising: using the color saturation variable photonic crystal material obtained via the above preparation method as a sacrificial template; filling the gaps between the monodispersed microspheres of the sacrificial template with functional materials, and then removing the sacrificial template.

La présente invention se rapporte à un procédé de préparation d'un matériau à base de cristaux photoniques à saturation des couleurs variable, ledit procédé consistant à : mélanger des microsphères monodispersées avec un solvant ; ajouter des composants compléments et effectuer une dispersion ultrasonique afin de former une émulsion uniforme ; placer l'émulsion obtenue dans un récipient composé d'un matériau hydrophobe qui présente une faible adhérence (F) < 500 μN à l'eau et un angle de contact avec l'eau (CA) ≥ 90° ; le solvant s'évaporant sur l'interface gaz-liquide à une température comprise entre 40 et 100 °C et à un taux d'humidité compris entre 5 % et 95 %, ce qui provoque l'auto-assemblage des microsphères monodispersées dans l'émulsion sur l'interface gaz-liquide, ce qui permet de former un matériau à base de cristaux photoniques ayant une structure opale. La présente invention se rapporte également à un procédé de préparation d'un matériau à base de cristaux photoniques ayant une structure opale inverse, ledit procédé consistant à : utiliser le matériau à base de cristaux photoniques à saturation des couleurs variable obtenu par l'intermédiaire du procédé de préparation mentionné ci-dessus sous la forme d'un modèle sacrificiel ; remplir les espaces formés entre les microsphères monodispersées du modèle sacrificiel avec des matériaux fonctionnels et, ensuite, enlever le modèle sacrificiel.

本发明提供一种色彩饱和度可调控光子晶体材料的制备方法,包括:将单分散微球与溶剂混合,加入助料,超声分散,形成均匀乳液;将所得到的乳液置于对水具有低粘附力(F)<500μN,且对水的接触角(CA)≥ 90°的疏水性基材的容器内,在温度为40~100℃,湿度为5%~95%的条件下,利用溶剂在气液界面上蒸发,引起乳液中的单分散微球可在气液界面发生自组装,形成蛋白石结构的光子晶体材料。本发明还提供一种反蛋白石结构的光子晶体的制备方法,包括:将上述的制备方法所制备得到的色彩饱和度可调控光子晶体材料作为牺牲模板,在牺牲模板的单分散微球之间的间隙中填充功能性物质后,再去除所述的牺牲模板。
