Plastics do develop static charge.  Ever had those Styrofoam peanuts stick

thank you everyone for your informative responses to my inquirey on 
static.
It is interesting how electrons can be rubbed off, and makes me wonder 
about friction and charges.

What is it about hair, combs, balloons, and clothings?
Why not a wood door? andwhy not plastics?

Subject: [BlindHandyMan] What Causes Static Electricity

Hi Everyone
Static electricity is usually caused when certain materials are rubbed
against each other, like wool on plastic or the soles of your shoes on the
carpet.
The process causes electrons to be pulled from the surface of one material
and relocated on the surface of the other material.

Rubbing a balloon on a wool sweater
creates charges on the surfaces

The material that loses electrons ends up with an excess of positive (+)
charges. The material that gains electrons ends up an excess of negative (-)
charges
on its surface.

Electrons pulled from orbit

The gain or loss of electrons can be explained by recalling that atoms
consist of a nucleus of neutrons and positively charged protons, surrounded
by negatively
charged electrons. Normally, there is the same number of electrons as
protons in each atom.

But if some object pulls away electrons from their orbit or shell around the
nucleus, that causes the atom to have a positive charge because it has more
protons than electrons. Likewise, the other material will have extra
electrons in its shell, giving the atoms a negative charge.

Charges on surface

Note that the charged atoms are on the surface of the material. Static
electricity is different than regular electricity that flows through metal
wires.
Most of the time the materials involved in static electricity are
nonconductors of electricity.

If electrical charges build up on the outside of a metal, most of them will
dissipate into the metal, similar to an electrical current.

Prefers dry air

When the air is humid, water molecules can collect on the surface of various
materials. This can prevent the buildup of electrical charges. The reason
has
to do with the shape of the water molecule and its own electrical forces.

Thus, static electricity is formed much better when the air is dry or the
humidity is low.

Force field causes attraction

An object that has static electricity charges built up on its surface has an
electrical force field coming from the surface. This field will mildly
attract
neutral objects or those with no charge. The field will strongly attract an
object that has an opposite charge on its surface. From this we get the
expression:
"Opposites attract."

If two objects have the same charge, the electrical force field will cause
those objects to push away from each other or repel.

Attraction

Rub a balloon on a wool sweater. The balloon collects negative electrical
charges on its surface and the wool collects positive charges. You can then
stick
the balloon to the wall, which does not have an excess of either charge. The
balloon will also stick to the wool, although the charges may jump back to
the original material in a short time.

You can also run a comb through your hair to charge the comb with static
electricity. The comb can then be used to attract neutral pieces of tissue.

Picking up tissue with a comb

Repulsion

Comb your hair on a dry day or after using a hair drier. The plastic comb
collects negative charges from the hair, causing the hair to have an excess
of
positive charges. Since like charges repel, the hair strand will tend to
push away from each other, causing the "flyaway hair" effect.

Why sparks fly

When two objects that have opposite charges get near each other, the
electrical field pulls them together.

What actually happens is that the negatively charged (-) electrons are
attracted to the atoms in the other material that have an excess positive
(+) charge.
Things are much more stable if all the atoms have an equal number of (+) and
(-) charges.

Strong forces hold electrons

The reason the electrons can't leave their present material is because of
strong molecular forces that keep them where they are. If there are enough
positive
(+) charges attracting them, and the distance is not too great, some of the
electrons will break loose and fly across the gap to the (+) side.

Once it starts

Once a few electrons start to move across the gap, they heat up the air,
such that more and more will jump across the gap. This heats the air even
more.
It all happens very fast, and the air gets so hot that it glows for a short
time. That is a spark.

The same thing happens with lightning, except on a much larger scale, with
higher voltages and current.

Ben Franklin

Ben Franklin proved that lightning was static electricity by flying a kite
in a storm and detecting static electricity by seeing the hairs on the kite
string
stand on end and creating a spark with a metal key. This dangerous
e
