Expert Answer:

If an atom has more electrons than protons, it is negatively charged. If an atom has more protons than electrons, then it is positively charged. If a material is more likely to capture electrons when in contact with another material, it is more negative.

Probably, you can find materials below that produce static electricity by rubbing.

The human body is positive. Fur, glass, nylon, wool, silk, and cotton, are considered to have a positive charge. Materials such as polyurethane, saran, styrene (Styrofoam), polyester, PVC, and Teflon, are negatively charged.
