The document summarizes a student workshop on polymers held in Al-Bairaq. The students conducted experiments to learn about different types of polymers and their properties. They explored how polymer pellets absorb water, compared the viscosity of polymer liquids, and tested the strength of polymer films. As a final project, the students proposed an idea to use piezoelectric polymers to generate electricity from vibrations in stadiums during the 2022 FIFA World Cup in Qatar. Their concept was to use piezoelectric films to convert pressure into voltage to power lights and digital displays sustainably. The students learned about polymers applications and teamwork through this workshop.

2. INTRODUCTION
• What are Polymers:
• Polymers are long chain molecules composed of
smaller units called “monomers”
• Examples:
• 1- piezo electric polymer
• 2- visco elastic polymer
• 3- poly venal acetate

3. OUTLINE
Activities:
• Act. 1: Changing Polymer Pellets
• Act. 2: Hunting for Polymers
• Act. 3: Comparing the viscosity of
liquids
• Act. 4: Testing the Strength and Strech
ability of Different Polymer Films
• Design Project: Designing a Humidity
Sensor
Our Product Idea : Electrifying stadiums

4. POLYMER WORKSHOP
ACTIVITIES IN AL-BAIRAQ
Act. 1: Changing
polymer pellets
Act.3:Comparing the
viscosity of liquids
Act.2:Hunting for
polymers
We experimented with
polyacrylamide pellets to
learn the absorption
properties. We have
noticed
That this polymer can
absorb water
200 times its size.
We have discovered That
Polymers are everyday used in our
life in the form natural polymers /
synthetic polymers , in food,
medicines, cosmetics, utensils,
furniture, construction and the list
goes on.
We learnt the concept of
viscosity of polymer
liquids.
We learnt to prepare
polymer films and noticed
that as the liquids are
more viscous, it became
harder to spread
on the films.

ACTIVITIES IN AL-BAIRAQ
Act.5:desining a
humidity sensor
Act.4: testing the strength
and the stretch ability of
different polymer films
We learnt the concept of viscosity of
polymer liquids.
We learnt to prepare polymer films
and noticed that as the liquids are
more viscous, it became harder to
spread
on the films.
We designed a non-
electrical humidity
sensor using polymers
like Poly Vinyl Alcohol,
solvent and indicator.

6. OUR PRODUCT IDEA
PIEZO 2022
What is Piezo?
The asymmetric shape of the atoms of piezoelectric
crystals of poly vinylidene difluoride (PVDF) creates
positive and negative poles sensitive to electricity . This
causes the crystal to produce a small voltage when it is
vibrated or when enough pressure is applied to change
the shape of the crystal. This effect is reversible; when an
electric voltage is applied, the crystal changes shape by a
small amount.

7. FINAL PROJECT:
PIEZO 2022
-Our project will be very important for
Qatar in the world cup 2022 because
that will reduce the pressure on
kahramaa and electricity stations .
-The purpose of our project is to
transform the resulting energy to an
electricity and turn on the lights in the
stadiums and every unit depending on

8. PIEZO 2022
MATERIALS AND METHODS
• Materials:
Pieces of PVDF films and complete Electric
circuit to transfer the voltage produced to the
devices.
• Method :
An electrical set up employing PVDF films to
sense pressure and produce voltage that will
be amplified to light up stadiums / the digital
banners in stadiums.

9. PIEZO 2022
BENEFITS
• An idea that will help Qatar in the
next world cup 2022 .
• Renewable energy source that
contributes to the sustainable
energy development.
• The set-up is of low cost and
easily manageable.

10. PIEZO 2022
RECOMMENDATIONS:
• We recommend that this idea
could be applied in the corridors
of malls, hospitals etc.
• This could generate large amount
of voltage enough to provide
lighting to the entire polymer.

11. CONCLUSIONS
• Throughout our journey , we learnt about different
polymers and their properties and applications in
everyday life and industrial applications.
• Moreover, we learn to design a new product idea
that could change the lives of people and make it
better.
• We learn to work as a team, build confidence and
improve our communication skills.
