| Summary: | Printed electronic is an emerging technology which the electronic devices are
printed on various type of substrates. The flexibility of the printed electronics have
enabled the shaping of these flexible electronic if they are printed on flexible substrate.
Thermoforming process has been introduced into the shaping of printed
electroluminescent(EL) on the plastic substrate. The main objective of this project is
to study the effect of thermoforming on the EL printed thermoplastic by utilising
ANSYS Polyflow simulation and Scanning Electron Microscope(SEM). Simulation
of the thermoforming process was done on a polyethylene terephthalate(PET) sheet to
obtain the thickness distribution on the simulated PET sheet. At the same time, the
thermoformed product was experimented using SEM to obtain the thickness
distribution of thermoformed product. The result from both approach showed that
there were different deviations in thickness at the different area of the thermoformed
product. However, the difference was acceptable due to the complex and curvature
design of the mold. Energy dispersive X-ray was done to determine the composition
of element in the thermoformed product. The results showed that the distribution of
EL materials were uneven after thermoforming process but the layers could still be
detected by analysing the composition of element in the layers. In conclusion,
thermoforming process is a suitable process for the shaping of printed electronics on
the thermoplastic substrate. |
