Polymeric materials are widely used in floor material in hospital, factories and detention centers but the charge which generated induced in triboelectric process are usually referred as a negative effect either in technological applications or scientific research and they are wasted energy in many cases. The present study aims to reduce the electrostatic charge (ESC) generated on polypropylene shoes during walking against the tested floor materials (A & B) through adhering stainless steel strips in the back of the floor material and pressing under applied different normal load for 10 seconds then separating to measure the electrostatic charge. The experimental result showed that, the electrostatic charge slightly increased by increasing the applied normal load and increasing the number of strips. This increasing refers to the phenomena of triboelectrification which generate a double layer of electric static charge on the two contact surfaces. The double layer of the electric static charge would generate an E-field on the floor material. Presence of stainless steel strips in adhered in the bake of floor material, would generate extra electric static charge on surfaces. The grounded system decreased that ESC which generated on the surface and it is clear that the floor material B generated lower ESC than that noticed by floor material B. The voltage decreased more in the presence of water/chlorine film thus because of the relative good conductivity of water.
