Items made of rubber, such as the soles of shoes or the wheels of a cart, are often at the bottom of the triboelectric series. When you pull a plastic comb through your hair, the friction transfers electrons to the comb.
Understanding How Material Science Causes Static Shock
Rubber is a prime example of a material that causes static electricity. When a rubber-soled shoe scuffs across a wool carpet, the rubber aggressively pulls electrons away from the wool.
This leaves the person walking with a negative charge that can discharge dramatically the moment they touch a grounded metal object. It occurs when an imbalance of electric charges builds up on the surface of a material.
The Shocking Role of Rubber and Plastic in Static Electricity
Role of Insulators in Static Buildup Conductors allow electrons to flow freely, making it difficult for a static charge to accumulate. Because the plastic does not conduct electricity down to your hand, the charge remains on the comb until it finds a path to ground, often resulting in the hair standing on end or the comb attracting small pieces of paper.
