研究目的
To analyze the effect of alumina nanowires (ANWs) doping on the textural and electro-optic properties of 5CB LC in two different cell configurations (planar and in-plane switching (IPS) mode) and to investigate the effect of cell configuration on the transmission, phases, phase transition temperature, and threshold voltage.
研究成果
Doping with ANWs increases the nematic to isotropic phase transition temperature, decreases threshold voltage, and improves contrast ratio and birefringence in both planar and IPS cell configurations. IPS cell configuration offers better contrast ratio but higher power consumption compared to planar cells. The energy band gap, being a material property, remains unaffected by cell configuration.
研究不足
The study focused on the doping effect of ANWs on 5CB LC in planar and IPS cell configurations. Limitations include the specific concentration of ANWs used (0.5% wt/wt) and the focus on textural and electro-optical properties without extensive exploration of other potential effects.
1：Experimental Design and Method Selection:
The study involved doping nematic liquid crystal (5CB) with alumina nanowires (ANWs) and analyzing its effects in planar and IPS cell configurations. The methodology included textural and electro-optical characterization using polarizing optical microscopy (POM), transmission electron microscopy (TEM) for ANWs characterization, and UV-visible spectroscopy for energy band gap measurement.
2：Sample Selection and Data Sources:
The host material was nematic liquid crystal 5CB, and the guest material was ANWs. The samples were prepared by mixing ANWs in 5CB LC, followed by stirring and ultrasonication.
3：List of Experimental Equipment and Materials:
Equipment included TEM (JEOL JEM-2100), POM (Nikon, Model-LV100POL), He-Ne laser (Melles Griot, 5 mW, 632.8 nm), Photo detector (PD02, Instec, USA), function generator (Tektronix, AFG 3021B), and UV-visible spectrometer (Carry 100, Agilent). Materials included 5CB LC and ANWs.
