electrostatic chalk duster

I would like to build a chalk duster that can attract the dust produced by a statically charged brush and store it in the body. I would like to know what materials can I use to make the brush and how to retain charge on it using AA batteries or capacitors. Please attach a mechanism for maintaining charge on the material if u have. Thank You
Such gadgets work on flowing air. They do not attract dust from a distance.

sir i don't want them to attract the dust from a distance .. i want them to ensure that when i rub the board chalk dust is attracted and stored within it thus not producing any flying dust .. i want suggestions on the materials to use and the method to induce charge on them with batteries
hi... I too wanted to build a similar device few months ago. But, I never took efforts. Good to know that someone is having similar ideas.
my thanks for the suggestions ... is the static electricity generator harmful in any way ?? any specific cautions that i'm supposed to take before using said device ??
You can get a tingle or a jolt depending on the voltage and quantity of charge.
