E-mail: felix. In this work, self-lubricating and electrically conductive polymers on a polypropylene PP matrix were prepared and investigated. These polymeric composites are expected to achieve coefficients of friction COFs comparable to lubricated systems. Combined with electrical conductivity, these materials could be applied in electrically loaded tribosystems. By varying the tribological test parameters, the application limits of self-lubrication were identified. It was demonstrated that the contact pressure has a strong influence on the COF.
Therefore, this work points to potential applications in e. This work focuses on polymer-based composites, enabling self-lubrication and electric conductivity by adding carbon-based additives and ionic liquids ILs with the aim of shedding light on the influence of testing parameters as described by the Stribeck curve in liquid lubricant systems.
This approach intends to meet two challenges posed to tribological systems. Electrical discharges that can occur in various applications e.
This prevents the formation of high voltages, which could damage the material and the lubricant e. In addition, the self-lubrication of the material should make the application of an external lubricant obsolete.
However, influences of testing parameters still need to be described. In the following, important results for this work shall be discussed. In the context of tribological application, certain polymers are gaining an increasing importance for technical applications due to their variability of properties by adding additives as well as their accessibility and workability.
