By embedding a film of highly aligned carbon nanotubes (CNTs) into a shape memory polymer (SMP), a fourfold increase in resolution of nanostructures raised on demand with a simple laser pointer is achieved. In the design of nanostructured compounds for micro‐optic and microfluidic lab‐on‐chip and security applications, the SMP's imprinted surface modifications act as the active part, while the CNT film aids their fabrication as an efficient broadband absorber converting light into thermal energy and initializing the polymer's shape memory effect. Due to its extraordinarily high thermal conductivity, the CNT film further acts as a highly efficient heat sink dissipating excess heat before it can blur the boundaries of the raised nanostructures’ region. A low‐cost fabrication method of those CNT–SMP compounds is presented and how the programming and recovery properties enable the production of nanoscale surface modifications with unprecedented simplicity, flexibility, and resolution is shown.

高分辨率按需纳米结构

通过将高度对齐的碳纳米管（CNT）膜嵌入形状记忆聚合物（SMP），可以使用简单的激光指示器将纳米结构的分辨率提高四倍。在用于微光学和微流体芯片实验室和安全应用的纳米结构化合物的设计中，SMP的压印表面改性是有效的部分，而CNT膜则有助于将其制成一种有效的宽带吸收剂，将光转换成热能并吸收热量。初始化聚合物的形状记忆效应。由于其极高的热导率，CNT膜还可以充当一个高效的散热器，在使凸起的纳米结构区域的边界模糊之前，可以散发过多的热量。
