I built a temporary darkroom in the unfinished basement of a rental home a long while ago. I used a double sheet of heavy black construction poly to partition the darkroom off. It was stapled to the floor joists above and I had 2x4s holding the sheets down on the concrete floor. The door was a simple double light trap using the poly. The material proved to be completely light tight but it caused such an enormous amount of static that I finally resorted to misting it and the floor with water prior to printing or unloading/loading film in order to control the dust. I imagine the 30 feet of poly 9 feet high in a double layer that constantly rubbed together every time a door opened or shut anywhere in the house contributed to the problem, but I certainly did not find the poly sucking the dust out of the air.
