Schematic illustration of cost carriers in ionomers and non-ionic polymer involved with FEP counter materials; electron, anion, and materials fragments (cationic polymer, FAA-3), electron and materials fragments (non-ionic polymer, nylon 66), and electron, cation, materials fragments (anionic polymer, Nafion 211).

Professor Dong-Myeong Shin and his group from the Division of Mechanical Engineering beneath the School of Engineering on the College of Hong Kong (HKU) make clear the contribution of ions in electrical cost switch, although their contribution differs with environmental humidity.
This discovery provides new insights into contact electrification, the phenomenon the place static electrical energy is generated when two completely different supplies contact after which separate. This impact is necessary for a lot of applied sciences, together with photocopiers, spray portray, power assortment, and self-powered sensors.
Difficult previous beliefs about cost switch
Of their research, titled “Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers,” revealed in Superior Purposeful Supplies, the group presents proof that each electrons and ions are transferred on the similar time when two stable surfaces come into contact. This challenges the long-held perception that solely electrons are answerable for producing static electrical…
