SUMMARY

The discussion centers on the use of leather for the bottom roller of a Van de Graaff generator, specifically the triboelectric properties of leather. Users confirm that the 'fuzzy' soft side of leather is more effective for generating charge. Additionally, it is clarified that using leather on the bottom roller and PVC on the top can allow for the dome to take on either a negative or positive charge, depending on the design. For optimal performance, the rough side of the leather should be used outward.

PREREQUISITES
  • Understanding of triboelectric series and materials
  • Familiarity with Van de Graaff generator construction
  • Knowledge of charge generation and polarity
  • Basic skills in DIY electronics and materials selection
NEXT STEPS
  • Research "DIY Van de Graaff generator construction techniques"
  • Explore the triboelectric series for material selection
  • Learn about charge polarity in electrostatic generators
  • Investigate the effects of different materials on charge generation
USEFUL FOR

Electronics enthusiasts, DIY project builders, students studying electrostatics, and anyone interested in constructing a Van de Graaff generator.

Hello everyone. I am trying to build a Van de Graaff generator for a project of mine (the triboelectric kind), and I have heard that leather is very high on the triboelectric scale, so I plan on using it for the bottom roller. However, I am not sure if this is referring to the smooth, tanned side of the leather, or the 'fuzzy' soft side. My initial tests conclude that it is the soft side, but I want to make sure.

Also, if I use leather on the bottom roller and PVC for the top, will the dome take on a negative charge? I was under the impression that it would, but after doing some research, I'm not sure anymore.

Yes, rough side out on the leather belt.

You can design it to make the top negative or positively charged.

I suggest searching for "DIY Van de Graaff" for more construction tips.
