Abstract
The scarcity of comprehensive information regarding the mechanism of static
generators and the effectiveness of different material combinations in generating significant
electrostatic charges remains as the most significant challenges in this project. Regarding this
issue, this research intends to fill this knowledge gap by examining the process of generating
electrostatic charge through glass-teflon and glass-nylon composite materials. The study was
carried out by adopting motor speed as the independent variable which ranged between 10m/s
and 50m/s. An electrostatic field meter was used to get the charges created and the findings
used to identify the ideal material pairing. The outcome revealed that both glass-teflon and glass-nylon couple produced more
electrostatic charges as the motor speed risen. However, the charges obtained herein revealed
that the glass-teflon combination gave higher charges consistently, by peaking at 27.3 nC at 50
m/s, compared to the glass-nylon combination, which reached 21.3 nC at the similar speed.
From these results, it is understood that the glass-teflon combination is more effective in
producing triboelectrification charges which perhaps results from the higher triboelectric series
of glass and teflon. By doing so, this research provides significant information on the enhancement of
electrostatic productions particularly in electrostatic generators, as well as the most suitable
materials to use in order to acquire the highest number of charges possible. As for the future
work, the improvement of the efficiency of charge collection, reduction of the insulator’s
leakage properties, and the modification of the Leyden jars’ construction to provide the best
conditions for discharge are to be considered. The solutions to these challenges will help in
further enhancements of electrostatic generators to provide better solutions.
