specific Embodiment approach 1
[0009] Specific embodiment one: the preparation method of a kind of vanadium pentoxide film with smooth surface of the present embodiment is carried out according to the following steps: one, by NH 3 ·H 2 O:H 2 o 2 :H 2 The volume ratio of O is 5:2:1 to NH 3 ·H 2 O, H 2 o 2 and H 2 O mixed to obtain mixed solution A, dilute H 2 SO 4 :H 2 o 2 The volume ratio is 3:1 will dilute H 2 SO 4 :H 2 o 2 Mix to obtain a mixed solution B, then place the glass substrate in the mixed solution A for 30min-35min ultrasonic vibration, and then place it in the mixed solution B for 30min-35min ultrasonic vibration, rinse the glass substrate with distilled water, and store it in a dry place. Standby in water and ethanol; 2. Press V 2 o 5 The mass volume ratio of powder to distilled water is 1g: 40mL~50mL, V 2 o 5 The mass ratio of powder to dispersant is 1:1.0~1.8 Weigh V 2 o 5 Powder, dispersant and distilled water; 3. Add the dispersant weighed in step 2 to the distilled w...
