The way the sentence is written, the verb attempted poly(vinylidene flouride). I think you mean that you attempted to use poly(vinylidene flouride). The other problem I see is that you say you made this attempt in the paper itself. I would imagine the attempt was made in a lab and described in the paper.

In this paper, we describe our attempt at using poly(vinylidene fluoride) nanofibers for fabricating a high-resolution low voltage FED with triode structure.

I have made some assumptions as to what you are trying to say, and I may be wrong. If I've changed your meaning, add a comment with some more context, and I will try again. I hope this helps.
