4. INTRODUCTION
With the invention of transistors in early half
of 19th century, the field of electronics has
undergone innummerable changes.
Entire concept of electronics is
based on semiconductors.
Silicon is most widely used in
manufacture on electronic
circuits.

5. WHY POLYTRONICS?
The widespread use of silicon electronic
goods has large number of disadvantages
some are,
Production of silicon embedded circuits
involves a huge investment .
More power consumption.
Not flexible.
Not portable.

6. Because of these disadvantages
researches and scientists all over the
world look for other alternatives.
For long, it was believed plastics were
materials with poor conductivity.
Researches proved that when plastics
are combined with other substances in
proper chemical compositions they can
behave as good conductors of electricity.
This has led to the emergence of
“Polytronics” where these limitation can
overcome.

7. POLYMER AND POLYTRONICS
Polytronics = polymer + electronics
“Poly”means many, “mer” means parts.
Polymer is a macromolecule, composed
of many repeated subunits.
In manufacture of electronic products
conjugated polymers are used.

8. Examples for conjugated ploymers: PVC,
Polyacetyelene, Polyethylene, etc.
Polymer conductivity, is known through its :
>Doping
>Mobility
>Ohm’s law
Thus these ‘PLASTIC CIRCUITS’ is one
alternative that would meet the technological
needs.

9. HISTORY
Hermann Staudinger was
a German organic chemist
who demonstrated the
existence of
macromolecules, which he
characterized as polymers.
For this work he received
the 1953 Nobel Prize in
Chemistry.

The 2000 Nobel Prize
for Chemistry was
awarded to three
researchers for their
work in conductive
polymers.

11. INK-JET PRINTING TECHNOLOGY
This technology provides continuous
production line of plastic circuits on plastic
substrates and then cut into individual units.
The substrates are made of
acetate material that is as
transparent as vugraph sheets.
This printing technology plays a
major role in the development of “flat screen”
display.

12. Construction of Topgate
Transistor:
These droplets
contains POLY (3,4-
ethylenedioxythiophene)
doped with Polystyrene
sulphonic acid.
The dried droplets are
coated with semiconducting
polymer (9,9-dioctyl
flourene-co-bithiophene)
followed by a dielectric layer
of Polyvinylphenol.
Finally gate is printed,
creating a Top gate
transistor.

13. APPLICATIONS
Plastic Batteries
OLEDs
Electronic Paper
Rubber circuit board
OFETs

14. PLASTIC BATTERIES
This battery material is
roughly 0.5 millimeters
thick.
It consists of 3 different
layers.
Zinc manganese dioxide
components as anode and
cathode which are like
thin plastic sheets.
Electrolyte is a polymer
gel placed between
electrodes.

15. ELECTRONIC PAPER
To overcome pollution due
to pulp industry, E-paper is
introduced.
This is a single sheet of
paper, that can be updated
via Internet and can be rolled
up tightly without any
damage.
Produced by Ink-jet printing
technology by using E-Ink
which is activated by electric
charge.

16. ADVANTAGES
Freedom in design.
Cost Effective.
Environment friendly.
Consumes less power.
Recycled and reused.
Compact portable products.
Light in weight.

17. CONCLUSION
 Polytronics is going to change the whole world of
consumer electronics and form the principal root for
the major advancement in the design of electronic
circuits and manufacture of printed circuit boards
(PCB).
So I conclude that, in the forthcoming years
Polytronics will accelerate the pace of the
technological advancements and describe a new
dimension in the near future.
