Generation of Static Electricity

Click For Summary
SUMMARY

The discussion focuses on calculating the generation of static electricity between two materials, specifically when material A is immersed in substance B and moves at a constant velocity. Key factors include the velocity, volume, surface area of material A, and the electron affinities of both materials. The complexity of the problem arises from the need to understand the molecular interactions between the surfaces, akin to calculating the coefficient of friction from first principles.

PREREQUISITES
  • Understanding of electron affinity concepts
  • Knowledge of surface area and volume calculations
  • Familiarity with molecular interactions and their impact on material properties
  • Basic principles of static electricity generation
NEXT STEPS
  • Research methods for calculating electron transfer rates between materials
  • Explore molecular dynamics simulations to analyze surface interactions
  • Study the principles of triboelectric charging and its applications
  • Learn about the coefficient of friction and its calculation from first principles
USEFUL FOR

Materials scientists, physicists, and engineers interested in the principles of static electricity generation and its practical applications in various fields.

I was wondering if and/or how one would could calculate the the generation of static electricity between 2 materials.

For example material A is immersed in substance B and moves within it at a constant velocity. Knowing the velocity and volume / surface area of material A and the electron affinities of both material A and substance B, could you calculate the rate at which material A loses / gains electrons?

I suspect you would need to know how the two surfaces interact at the molecular level. That would make it a difficult problem. Perhaps similar to trying to calculate the coefficient of friction from first principles.
