Embodiment 1
[0031] (1) 97.95 parts of MMA and 0.05 part of ABVN (initiator) and 2.00 parts of hydroxyethyl methacrylate (HEMA) were mixed uniformly in a 250mL flask;
[0032] (2) Place the flask in an oil bath at 80°C for prepolymerization, connect a spherical condenser and a thermometer (PID) to the flask to control the temperature, keep the system at 80°C for 20 minutes, and wait for a large number of bubbles to emerge from the flask About 10s, the prepolymerization is over, take the flask out and put it in an ice-water bath until the wall of the flask becomes cold, and degas the prepolymer by applying vacuum (650mmHg) to remove air bubbles and dissolved air;
[0033] (3) The commercially available glass plate was washed three times with ethanol and deionized water respectively, and dried, and then the glass plate was immersed in an acetone solution (100.00 g) containing 1.50 g of hexadecyltrimethoxysilane (HTEOS) for 10 s to make Its surface is hydrophobic. After pretreatment, dry at ...

[0036] (1) Mix 97.95 parts of MMA, 0.05 parts of ABVN and 5.00 parts of HEMA in a 250mL flask;
[0037] (2) Place the flask in an oil bath at 80°C for prepolymerization, connect a spherical condenser and a thermometer (PID) to the flask to control the temperature, keep the system at 80°C for 20 minutes, and wait for a large number of bubbles to emerge from the flask 10s, the prepolymerization is finished, the flask is taken out and placed in an ice-water bath until the flask wall becomes cold, and the prepolymer is degassed by applying a vacuum (650mmHg) to remove air bubbles and dissolved air;
[0038] (3) Wash the commercially available glass plate three times with ethanol and deionized water respectively, and dry it, then immerse the glass plate in an acetone solution (100.00 g) containing 1.50 g of hexadecyltrimethoxysilane (HTEOS) for 10 seconds to make it The surface is hydrophobic. After pretreatment, dry at room temperature for 60 minutes;
