Embodiment 1
[0039] A preparation process for a light-adjustable heat-insulating glass substrate, the preparation process comprising the following preparation steps:
[0040] 1) Put quartz glass as the inner matrix in a mixture of 3-aminopropyltriethoxysilane and 3-aminopropyltrimethoxysiloxane with a mass ratio of 1:0.7 and a total mass concentration of 35wt%. Activation treatment to obtain an activated inner matrix;
[0041] 2) Prepare the magnetic starch microspheres into a suspension, put the activated inner matrix obtained in step 1) into the suspension, and deposit it under the condition of an external magnetic field until the surface of the activated matrix is covered with a layer of semi-permeable film Washing with water to obtain the inner matrix with magnetic starch microspheres deposited on the surface;
[0042] 3) Coat the surface of the inner substrate with magnetic starch microspheres deposited in step 2) with polyamide solution, cast into a film and place it in an environme...
