Abstract

This study introduces a UV-curing resin leveraging the Christiansen effect to achieve dynamic color modulation in phase-separated elastomers (PSE) through solvent composition and temperature control. By matching refractive indices between solvent (dimethyl phthalate/tributyl citrate) and polymer phases, PSE selectively transmits-specific wavelengths, enabling continuous color shifts from red to purple. The elastomers exhibit robust mechanical properties (>600% elongation, >300 kPa modulus) and function across a broad temperature range (−25°C–130°C). Compatible with 3D printing, the resin enables real-time solvent adjustments during fabrication, supporting spatially continuous color transitions without parameter modifications. This approach advances applications in adaptive optical devices, temperature-responsive displays, and multi-material 3D printing, offering a dye-free strategy for structural coloration in smart materials.

一种3D打印uv固化树脂，可使弹性体连续变色

本研究介绍了一种利用Christiansen效应的紫外光固化树脂，通过溶剂组成和温度控制来实现相分离弹性体（PSE）的动态颜色调制。通过匹配溶剂（邻苯二甲酸二甲酯/柠檬酸三丁酯）和聚合物相之间的折射率，PSE选择性地透射特定波长，实现从红色到紫色的连续颜色转换。弹性体具有强大的机械性能（>；600%伸长率，>；300 kPa模量），并能在较宽的温度范围内（- 25°C - 130°C）工作。与3D打印兼容，树脂可以在制造过程中实时调整溶剂，支持空间连续的颜色过渡，而无需修改参数。这种方法推进了自适应光学器件、温度响应显示器和多材料3D打印的应用，为智能材料的结构着色提供了一种无染料策略。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
