- Does the friction produced when hair comes in contact with the balloon affects the amount of static eletricity generated?

Adhesive force takes electrons

A force called the adhesive molecular force holds materials together. But when two different materials are pressed together and then pulled apart, the adhesive molecular force pulls electrons from one material and deposits unto the other. This creates the separation of charges or static electricity.

Although your can create static electricity by pressing materials together and pulling them apart, rubbing them together usually works even better.

One unfortunate result from saying that rubbing materials creates static electricity is that most people think that friction causes the charges to build up. It is not friction that causes static electricity, rather it is the adhesive forces that pull off electrons.

Friction does not play a part in producing static electricity
