It is known, that In order to decrease the electrostatic charge of a surface one has to apply some sort of conductive coating.
But, what if you want to achieve the opposite, i.e. maximise the electrostatic charge, e.g. for binding of dust etc.? Which coatings would be applicable?

Go with electrets. In the US, nonwoven electrets are sold as furnace filters to attract dust. They certainly work quite well as seen with the naked eye.
