Abstract

Electric static charges generated from friction of engineering materials have a negative effect in their applications. The increased use of polymeric materials raised the importance of studying that effect. Electric static charges building up on human skin and or clothes in direct contact with human body are very harmful and can create serious health problems. The present study investigates the electric static charge generated from the dry and water wetted sliding of shoe sole against floor for people who are working in hospitals.
 
It was found that friction coefficient displayed by dry sliding of polypropylene shoe sole against epoxy floor decreased with decreasing normal load, where the values were reasonable to avoid the foot slip. Friction values at light loads guaranteed the good adhesion of the shoe sole against floor. They are enough for safe use at dry sliding condition. Sliding of shoe against floor at dry condition generated much higher electric static charge measured on the shoe. This observation can confirm the necessity to develop new materials to be applied as shoe sole of low electric static charge. At sliding, the charge value was higher than that recorded for contact and and separation.At water wetted contact, the values of friction and electric static charge were lower than that observed for dry contact. It seems that the low values of electric charge were from the ability of water to conduct the charge from the contact surfaces.
