这一发现激发了研究团队的探索热情。在对材料的纹理控制上,他们利用高精度的电子束光刻工具,在聚合物薄膜上“微雕”出各种图案。当薄膜被浸入不同液体中时,会发生可逆的局部膨胀或收缩,从而隐藏或显示预设的纹理图案。在颜色控制上,则采用了一种精巧的光学结构,将薄膜夹在两个极薄的金属层之间,使之构成一个“法布里—珀罗谐振腔”(一种光学谐振装置)。这一结构如同给材料装上了精密的“调音器”,可精确控制薄膜不同区域的溶胀程度,改变器件对特定颜色光的反射率,从而呈现不同的结构色。

Keychron’s Q8 and Q10 are both up-market offerings that maintain the same Alice-style ergonomic layout and gasket-mount system, while swapping the lightweight plastic case for a heftier all-metal housing. The result is a denser keyboard and a more durable shell, with improvements to both typing sound and feel.
