Benefits of technology

It describes a new way to make thin layers that are resistant against water penetrating through them without losing their effectiveness or causing damage during use. These methods involve adding hydroxymethylenetriazole (HMB) molecules into solutions containing hydrazone acid chlorides at specific concentrations for producing polymers called poly(hydroxyimidodendronium)-chloroformate). By controlling how much HMB solution was added, it could produce various types of polyanions like those found naturally occurring in plants such as guayulea baccata leaves. Additionally, these techniques allow for creation of complex shapes made from multiple materials simultaneously while maintaining good electrical insulation characteristics over longer periods of time.

Problems solved by technology

Embodiment 1

[0034] PDI With DMF to 10 -4 mol:1L ratio mix, add 10 -2 mol: 1L of hydrazine hydrate, ultrasound the mixed solution for 1h; place the positive and negative electrodes in the system, with platinum electrodes as negative electrodes and ITO conductive glass as positive electrodes, the size of the positive and negative electrodes is 1cm×2cm, and the spacing is 10mm , And use detergent, water, ethanol, acetone, ultrasonic cleaning, vacuum drying for 1h; electro-deposition with constant potential method, working voltage of 1.0V, deposition at room temperature (25℃) for 2min; film will be deposited Take out the conductive glass, place it in a closed container and dry it naturally for 5 hours, and then dry it at 80°C under vacuum for 5 hours. The preparation work is completed.

[0035] The structural formula of the PDI film prepared in this embodiment is: The molecular formula is C 26 H 14 N 2 O 4 , The molecular weight is 418.4.

Embodiment 2

[0037] Same as Example 1, but the PDI structural formula is:

[0038] The molecular formula is C 40 H 26 N 2 O 6 , The molecular weight is 630.64.

Embodiment 3

[0040] Same as implementation 2, but PDI and DMF are divided by 10 -5 The ratio of mol:1L is mixed. The structural formula, molecular formula and molecular weight of the PDI film prepared in this embodiment are the same as those in the second embodiment.

Abstract

The invention relates to a method for preparing a perylene polyimide derivative film in the technical field of photoelectric materials. In the method, hydrazine hydrate is used for replacing trifluoroacetic acid, a positive electrode deposition method is adopted, and a dense and uniform film is prepared with a low voltage of 0.5-5V and a low current of 0.02-5mA within a relatively short deposition time. Moreover, composite films conforming to various absorption ranges are prepared through changing the structure and the matching of the perylene polyimide derivative.
