Traditional thermochromic materials prioritize high sensitivity and rapid discoloration. Reversible thermochromism with delayed discoloration is highly desirable for applications like thermal history indicators energy-saving windows, yet it has rarely been achieved. Here, we construct such composites simply by assembling hydrophobic silica nanoparticles in a polydimethylsiloxane (PDMS) matrix. The films transition from colorless translucent to blue within minutes when heated above 60 °C retain their color over eight hours at 20 °C. Remarkably, the time can be further extended lowering environmental relative humidity. Integrating measurements of water absorption, refractive indices, optical model calculation, demonstrate that coloration rises combined effects Rayleigh scattering multiple prolonged surprisingly caused gradual absorption moisture. This unique material opens new avenues advancing technology applications.

Abstract Although 3D micropattern has received considerable attention due to their remarkable usability, the introduction of specific functions, such as “chromism”, is still a challenge mainly lack adequate functional materials that can be introduced into printing system. In this study, micropatterns with temperature‐responsive properties are created by elaborately aligned thermochromic polymer microfibers using charge reversal electro‐jet writing (CREW) method printer. A reversible color change in response temperature exhibited micropattern, displaying various chromic colors, red, blue, and black, at own temperatures. Multiple‐color phases sequentially expressed single structure incorporating pigments different colors distinguishable shift ranges. Various patterning methods proposed for manufacturing diverse patterns demonstrating applications combinations color. addition directly increasing temperature, process induced heat generated from external factors electrical energy. These CREW extended fields, including sensors, clothing, anti‐counterfeiting.
