Create more and more triboelectric charges on polymer surface

Fundamental Research
Electrostatic potential induced by contact/tribo electrification on the polymer surface is often regarded as a hazard to be avoided, since it is usually the cause of electrical sparks and accidental fires. However, this electrification effect can also be

Revealing the Role of Interfacial Charge Transfer in Mechanoluminescence

Nanomaterials
Mechanoluminescence (ML) involves light emission induced by mechanical stress, categorized into triboluminescence (TL), piezoluminescence (PL), sonoluminescence (SL), and triboelectrification-induced electroluminescence (TIEL).

ELECTROSTATIC PROCESSES IN POWER CABLES

Electrical engineering & Electromechanics, 2013
Observation of contact electrification of power cable samples is made. It is revealed that the contact potential difference and the capacity formed under separation of free charges on the surfaces of the contacting materials depend on cable design ...

Flexoelectricity driven elastic contact–separation model for triboelectrification

Friction
Triboelectrification is the transfer of electrical charge between surfaces during contact. When the contact is purely normal (i.e., no sliding), the term contact electrification is often used.
