2. BACKGROUND OF ELECTRONICS….
With the invention of transistors in early half of
19th century, the field of electronics has
undergone innumerable changes
Entire concept of electronics is
based on semi-conductors
Silicon is such most widely used
material in manufacture of
electronic circuits
3. DISADVANTAGES BY USAGE OF SILICON….
Production of silicon embedded circuits involves
a huge investment
These circuits also consume more power
Silicon chips are not flexible
Products made by use of silicon
are not portable
This has led to the emergence
of “Polytronics”
4. WHAT IS POLYTRONICS ….??
Polymer electronics is shortly defined as
“Polytronics”
‘Poly’ means ‘many’ and ‘mer’ means ‘parts’
Polymer is a macro molecule composed of many
repeated sub-units
In this field conjugated polymers are widely used
in the manufacture of electronic products
5. HOW DOES A POLYMER CONDUCTS ..?
By obeying Ohm’s law
Ohm’s law defines conductivity in polymers as flow
of electrons or ions
The steps involved in conduction are
a) Doping
b) Mobility of electrons
c) Conductivity
6. ADVANTAGES…..
Freedom in design
Cost effective
Environment friendly
Compact portable products
Consumes less power
Increased picture quality in display devices
Recycled and reused
Light in weight and small
