MITRA Forum Question Details

ApproveRejectUn-ApproveIt's used in a workshop called "Tinkering new media", for students where they're trying out all kinds of stuff. So they will be using it for all sorts of things. Some use it in a painting, some on textiles, some on wood, etc. So flexibility and resillience: yes, preferrably. That is why I am using an acrylic binder, up until now. I think the solvability of gum arabic might be a problem for them. Thx, Matthijs Hendriks

ApproveRejectUn-ApproveI see that my last post did not make it to this forum. I'll post again: I am running the Painting Workshop on an Art Academy, and so I do make paint with students from scratch, every now and then. I think it's a good idea to have students make paint at least once, to give them a feel for it. In this workshop ' Tinkering new Media", which is done together with the Electronics Workshop in our academy, the students are making everything from scratch. So indeed I want them to make their own conductive paint themselves. So I hope some scientists here have a solution for my question :-) .

ApproveRejectUn-ApproveThanks so much. Until now I used 1 part graphite to 3 parts acrylic binder. That way it is still conductive, but it will rubb off. I also tried 1:6 and that won't rubb off, but it is not conductive anymore. Perhaps I could use a different pigment? Charcoal should work, maybe it won't rubb off as easily as graphite does. I am not sure how well it conducts, though. I am wondering what is used in the prepaired conductive paint that one can buy at the store, both binder and/or pigment. But I now understand why this stuff is so terribly expensive.

ApproveRejectUn-ApproveA little bump :-) . So it seems there is no simple solution to my problem....?

ApproveRejectUn-ApproveVery much appreciated! I could imagine that there is another pigment that does the same as graphite does, but doesn't need as much binder. Perhaps something like charcoal just does the thing, I could try and find out.... I'll let it know!
