研究目的
To fabricate phototunable photonic crystals with hierarchical microstructures by coating linear liquid crystal polymer (LLCP) onto the natural Morpho butterfly wing (MBW) and to study their photoresponsiveness.
研究成果
The study successfully demonstrated a new approach to fabricate phototunable photonic crystals with hierarchical microstructures by coating LLCP onto MBW. The deformation of hierarchical microstructures induced by UV light led to significant optical changes, showing potential for applications in sensors, photochromic pigments, and information storage technologies.
研究不足
The study focuses on the deformation of hierarchical microstructures and their optical properties under UV irradiation, but the practical applications in sensors, pigments, and cosmetics require further exploration for durability and scalability.
1：Experimental Design and Method Selection:
The study involved depositing azobenzene-containing linear liquid crystal polymer (LLCP) onto MBW through electrospinning, followed by melting and annealing to achieve a photoresponsive LLCP-MBW composite.
2：Sample Selection and Data Sources:
MBW was used as the biotemplate.
3：List of Experimental Equipment and Materials:
Equipment included a field emission scanning electron microscope (FESEM), atomic force microscopy (AFM), and reflection spectrometer. Materials included LLCP and MBW.
4：Experimental Procedures and Operational Workflow:
LLCP was electrospun onto MBW, melted, and annealed. The photoresponsiveness was studied under UV and visible light irradiation.
5：Data Analysis Methods:
Reflective spectra were analyzed to observe changes in reflectance and peak shifts.
