As kiteman says- take your pick from the list.

Your area of interest is in the Triboelectric series that shows how well different materials generate static electricity

i am wondering which material would be best for the belt as i have seen van de graaff's belts made of a variety of materials

The further apart a pair of materials are listed, the better the effect, especially if one is positive and the other negative.
