MEEN 3344 Materials Light Emitting Polymers


Light Emitting Polymers

-A light emitting polymer is an electro-luminescent plastic. The molecules of this plastic emit light when an electric field is applied.

-Polymer based light-emitting diodes (LED) were discovered in 1990.

-Cambridge Display Technology has the core patents for the Technology of LEP.

Electroactive Polymer (EAP) Actuators


Electroactive Polymer Technology

Electroactive polymers (EAP) are promising as actuators in intelligent material
systems, where large deformations are required. Electromagnetic, piezoelectric
or shape memory alloy actuators are either too heavy, too complex or too slow
for such applications. EAP however are relatively lightweight, rather simple and
fast enough.
In particular, dielectric electroactive polymers were shown to have good ove ....etc

Light-emitting polymers



ABSTRACT
The seminar is about polymers that can emit light when a voltage is applied to it. The structure comprises of a thin film of semiconducting polymer sandwiched between two electrodes (cathode and anode).When electrons and holes are injected from the electrodes, the recombination of these charge carriers takes place, which leads to emission of light .The band gap, ie. The energy difference between valence band and conduction band determines the wavelengt ....etc

ELECTROACTIVE POLYMERS(EAP)
ABSTRACT
Electro active polymers are soft actuation materials that are fastly replacing the conventional actuating materials such as piezo electric crystals, motors, screws etc:- As the name suggests, they essentially consists of a ionic polymer back bone metallic composite having positive counter ions. On the application of an electric field or small voltage, these EAP s will bend towards the anode.
They have properties resembling human muscles and ar ....etc

INTRODUCTION

Light emitting polymers or polymer based light emitting diodes discovered by Friend et al in 1990 has been found superior than other displays like, liquid crystal displays (LCDs) vacuum fluorescence displays and electro luminescence displays. Though not commercialised yet, these have proved to be a mile stone in the filed of flat panel displays. Research in LEP is underway in Cambridge Display Technology Ltd (CDT), the UK.

In the last decade, several other display contenders such as plasma and field emission displays wer ....etc
