Formation of a triboelectric series depends on the number of contacts over time between materials.
The most basic physics is well understood, but long-standing mysteries remain, most notably how different materials exchange positive and negative charges—sometimes ordering themselves into a predictable series, but sometimes appearing completely random. For their experiments, they decided to use plastic blocks made out of a clear silicon-based polymer called polydimethylsiloxane (PDMS) and measure how different samples exchanged charge under different conditions.
