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.
