Embodiment 1
[0055] A method for preparing a highly sensitive mechanically regulated smart window film, the steps are as follows:
[0056] (1) Preparation of SiO 2 Nano microsphere dispersion liquid and dispersion blue E-4R low binding force molecular material solution;
[0057] SiO with an average particle size of 300 nm was added at a concentration of 10 mg / mL 2 The nanospheres were dispersed in isopropanol, and evenly dispersed SiO 2 Nano microsphere dispersion;
[0058] Dissolve the disperse blue E-4R low-binding molecular material in acetone at a concentration of 1 mg / mL, and after ultrasonication for 30 minutes, prepare the disperse blue E-4R low-binding molecular material solution;
[0059] (2) Two-step spraying;
[0060] SiO 2 The nano-microsphere dispersion is loaded into the Master spray gun (spray gun model G44) and sprayed 10 times on the substrate with a spraying pressure of 50KPa, a spraying distance of 5cm and a moving speed of 5cm / s, and then disperse blue E-4R low bin...
