研究目的
Investigating the effect of CdSeS/ZnS QD on phase transition, morphological, electro-optical and dielectric properties of PDLC composites.
研究成果
The introduction of CdSeS/ZnS QD significantly changes the physical properties of PDLC, including phase transition temperature, droplet size, threshold voltage, and dielectric parameters. These changes suggest that PDLC/QD composites could be promising for future LC-based device applications.
研究不足
The study focuses on the effect of a specific type of QD on PDLC composites, and the results may not be generalizable to other types of QDs or composite materials.
1：Experimental Design and Method Selection:
The PDLC was prepared with nematic liquid crystal (E63) and UV-curable photopolymer (NOA65) by using a polymerization induced phase separation technique.
2：Sample Selection and Data Sources:
E63 coded nematic LC and CdSeS/ZnS QD were purchased from Sigma-Aldrich Chemical Company.
3：List of Experimental Equipment and Materials:
Dielectric/impedance analyzer, electro-optical switching method, differential scanning calorimeter, scanning electron microscope.
4：Experimental Procedures and Operational Workflow:
Samples were prepared by mixing LC and QD, then filled into LC cells and exposed to UV light. Dielectric, electro-optical, and morphological measurements were performed.
5：Data Analysis Methods:
Dielectric properties were analyzed using Cole-Cole plots, and electro-optical behaviors were evaluated through transmittance-applied voltage plots.
