Flexible Pressure Sensor Based on Carbon Black/PVDF Nanocomposite

Victor K. Samoei, Ahalapitiya H. Jayatissa & Keiichiro Sano · Chemical Science International Journal · 2024

A piezoresistive flexible pressure sensor was fabricated using carbon black and Poly (vinylidene fluoride) (CB/PVDF) composite. The conductive CB/PVDF composite was prepared by a wet-cast method and deposited onto a flexible polyethylene (PE) substrate. The surface morphology, cr...

Effect of Humidity on Friction of Molybdenum Disulfide Films Produced by Thermal Evaporation on Titanium Substrates

Bodhi R. Manu & Ahalapitiya H. Jayatissa · Chemical Science International Journal · 2020

MoS2 is one of the most advanced solid lubricants that have been used in many machineries. In this work, the effect of humidity on the friction of MoS2 solid film lubricant is investigated using a pin-on-disk tribometer. MoS2 film was coated by a thermal evaporation method on a t...

Characterization of the Effect of Moisture on Tribology of Titanium Rubbed Against Different Pin Materials

Bodhi R. Manu, Adam M. Schroeder & Ahalapitiya H. Jayatissa · Chemical Science International Journal · 2020

Tribology investigations were conducted to understand the effect of humidity and water adsorption at the interfacial surface on the friction coefficient of titanium. Pin-on-disk tribometer tests were conducted at different levels of humidity ranging from 0% to 71% RH using alumin...
