PVDF poling Device Query

Jan 25, 2005 3 Replies

Hello!



I want to pole PVDF films in my Lab. I prepare P(VDF TrFE) films by dissolving polymer pellets in a solvent(DMAC) and heating the mixture till Solvent evaporates. I then Stick Copper films as electrodes on the 2 sides of the film, and solder wires to the films.



For poling, I simply connect these wires to a 2KV Voltage source. Wait for 5 Hours, and hope that the film's poled. I dont have any control over any parameters.



My queries are as follows:



Can you suggest a better, faster method of poling? Some method which will allow me to control the level of poling ?



Should the film be poled above Curie Temperature or just below it?



What are the parameters which can be measured during poling ?



Is there any Poling Product available in the market, which I can buy?



Is there any product which will help me do Corona-Poling on my film? I would appreciate, if some helps me in this regard. Thankyou, Miheer.



This looks like it might be a good article to order.

The abstract claims that increasing the temperature from 25 C to 125 C decreases the poling time from hours to seconds.

I want PVDF on glass or ITO-coated (conductive coating) glass slide. I want the PVDF surface to be available without coating it with any other material. Does anyone know of any other technique?

PVDF film is available. You MIGHT be able to adhere it by heating it. I would not expect much adhesion.
