Example Embodiment
[0036] Example 1
[0037] Add 0.6g sodium lauryl sulfate, 100mL deionized water, and vigorously stir into a 250mL four-neck flask equipped with mechanical stirring, thermometer and reflux condenser; add 5.0g methyl methacrylate and 5.0g butyl acrylate after 20 minutes Ester; nitrogen gas, control the temperature at 85 ℃, add 0.100g potassium persulfate after 30 minutes, and end the reaction after 5 hours to obtain the binder emulsion. After mixing the binder emulsion with a polystyrene microsphere emulsion with a mass concentration of 10% and a microsphere particle size of 265nm in a volume ratio of 1:15, ultrasonically disperse it for 10 minutes, and drop it evenly on the glass slide. The bottom of the glass slide is heated to 50 degrees Celsius, and after the water volatilizes, a polystyrene photonic crystal with enhanced strength is obtained. The photonic crystal is immersed to a mass concentration of 0.1% cationic surfactant cetyltrimethyl In ammonium chloride, the anion and...

[0041] Example 3
[0042] Add 0.6 g of sodium lauryl sulfate, 100 mL of deionized water, and vigorously stir in a 250 mL four-neck flask equipped with mechanical stirring, thermometer and reflux condenser; add 10 g of ethyl acrylate after 20 minutes. Blow nitrogen gas and control the temperature to 85°C; add 0.100g potassium persulfate after 30 minutes, and end the reaction after 5 hours to obtain the binder emulsion. After mixing the binder emulsion with a polystyrene microsphere emulsion with a mass concentration of 10% and a microsphere particle size of 233nm in a volume ratio of 1:10, ultrasonically disperse it for 10 minutes, and drop it evenly on the glass slide. The bottom of the glass slide is heated to 50 degrees Celsius, and after the water volatilizes, a polystyrene photonic crystal with enhanced strength is obtained. The photonic crystal is immersed to a mass concentration of 0.1% cationic surfactant cetyltrimethyl In ammonium chloride, the anion and cation groups ar...
