A convenient technique is presented for determination of triboelectric characteristics of a film sample relative to a group of reference surfaces and to other film samples, with the use of inexpensive, easily assembled equipment. It consists of pressing a number of reference surfaces into contact with a test film, determination of the sign and intensities of the charges generated, by spraying with an indicating powder, and estimation of tribo‐electric position of the test sample by the distribution of positive and negative charges generated. With this technique, relative triboelectric characteristics were determined for films of various polymers. The measurements give some insight into the relation between polymer structure and triboelectric characteristics.
