Description
Summary:In this paper, inspired by the human‐giving goosebumps process, we demonstrated a rapid, versatile, and simple method to prepare anti‐UV microstructures polymer blend films with good morphology based on phase separation. Through the results of characterizations, it is proved that the microstructures are formed by polymer phase separation. Then the formation possibility of microstructures is proved by thermodynamic analysis. Moreover, the phase‐field model is used to simulate the formation of microstructures by the finite element method, which can illustrate the evolution process of the microstructures. Besides, the microstructures were prepared on different substrates through the simple phase separation method, which can verify the versatility of this method. In addition, the anti‐UV performance of the micro‐structure films was evaluated. This work proposed a simple and versatile route to prepare microstructures coating in different substrates, which exhibit well anti‐UV performance, and this work has the application potential for preventing material aging caused by UV radiation.
