Abstract:

The Phenomenon of Laser-Induced Discharging in an Organic Photoconductor Sample Was Directly Observed Using Electron Holography and Sophisticated Techniques for In Situ Observations. Mechanical Friction Was Used to Induce Negative Tribocharges on the Surface of the Photoconductor Sample. the Observation of Equipotential Contour Lines (i.e., the Electric Potential Distribution) outside the Specimen Revealed that the Amount of Tribocharges Was Reduced by the Laser Exposure. Computer Simulations of the Equipotential Lines Provided Useful Information for Evaluating the Quantity of Tribocharges.

Abstract:

One-fourth of the global energy losses result from friction and wear. Although friction and tribocharging were presented to be mutually related, reduction of friction and wear by eliminating tribocharges on common polymers, and decrease of power losses in devices with polymer parts were not shown to date. Here, we demonstrate that for common polymers, friction—which is strongly related to surface charge density—can be notably reduced by various methods of tribocharge mitigation, namely, corona discharging, solvent treatment, or placing a grounded conductor on the backside of one of the shearing materials. In our simple demonstrations, we found that by preventing tribocharge accumulation, a remarkable two-thirds of power loss during operation of simple mechanical devices with common polymers and plastic parts can be saved and wear can be reduced by a factor of 10. These demonstrations indicate important practical ramifications in mechanical systems with insulating parts.

Abstract:

Replica molding-based triboelectrification has emerged as a new and facile technique to generate nanopatterned tribocharge on elastomer surfaces. The “mechano-triboelectric charging model” has been developed to explain the mechanism of the charge formation and patterning process. However, this model has not been validated to cover the full variety of nanotexture shapes. Moreover, the experimental estimation of the tribocharge’s surface density is still challenging due to the thick and insulating nature of the elastomeric substrate. In this work, we perform experiments in combination with numerical analysis to complete the mechano-triboelectrification charging model. By utilizing Kelvin probe force microscopy (KPFM) and finite element analysis, we reveal that the mechano-triboelectric charging model works for replica molding of both recessed and protruding nanotextures. In addition, by combining KPFM with numerical electrostatic modeling, we improve the accuracy of the surface charge density estimation and cross-calibrate the result against that of electrostatic force microscopy. Overall, the regions which underwent strong interfacial friction during the replica molding exhibited high surface potential and charge density, while those suffering from weak interfacial friction exhibited low values on both. These multi-physical approaches provide useful and important tools for comprehensive analysis of triboelectrification and generation of nanopatterned tribocharge. The results will widen our fundamental understanding of nanoscale triboelectricity and advance the nanopatterned charge generation process for future applications.

Abstract:

The aim of this study was to investigate and analyze the separation process of poly (ethylene terephthalate) and high-density polyethylene mixture. The research studied the influence of parameters of tribocharging and separation processes on the quality of separation. The research was carried out using a developed test stand consisting of a test tribocharger and a dedicated drum-type electrostatic separator. Both the separator and the tribocharger have been designed as automated test benches to assess the quality of plastic separation. In order to assess the quality of electrostatic separation of plastics, an original method based on the use of a dedicated vision system was used. The research was conducted in two stages. Firstly, the influence of the tribocharging process parameters on the efficiency of the process, i.e., the charge collected, was investigated. The next stage of the research was focused on the analysis of the influence of the separation process parameters on its effectiveness. The obtained results were presented and discussed. On the basis of the conducted research, the parameters of the tribocharging and separation processes affecting their effectiveness were determined.

Abstract:

Abstract It is a long-standing open question whether electrification of wind-blown sand due to tribocharging—the generation of electric charges on the surface of sand grains by particle–particle collisions—could affect rates of sand transport occurrence on Mars substantially. While previous wind tunnel experiments and numerical simulations addressed how particle trajectories may be affected by external electric fields, the effect of sand electrification remains uncertain. Here we show, by means of wind tunnel simulations under air pressure of 20 mbar, that the presence of electric charges on the particle surface can reduce the minimal threshold wind shear velocity for the initiation of sand transport, u *ft, significantly. In our experiments, we considered different samples, a model system of glass beads as well as a Martian soil analog, and different scenarios of triboelectrification. Furthermore, we present a model to explain the values of u *ft obtained in the wind tunnel that is based on inhomogeneously distributed surface charges. Our results imply that particle transport that subsides, once the wind shear velocity has fallen below the threshold for sustained transport, can more easily be restarted on Mars than previously thought.

The thesis is devoted to development and diagnostic system for substantiation triboelectric potential to detect changes in surface properties of polymer isolation in aging cables under the strong electric field, high temperature and radiation. The distribution of surface charge density and voltage drop along the length of symmetrical insulated conductors in the presence of the gap between them and the defective thin layer on the surface of the polymer insulation was established based on the analytical solution. Experimentally determined the values of triboelectric potential and its dynamics of change in the process of accelerated termoradiation aging polymer cable insulation depending on the design of applied materials. There is a significant (threefold) increase in the maximum value of the contact potential difference and achieve maximum torque bias towards smaller values for single core power cables with cross-linked polyethylene insulation 6 kV after accelerated aging thermoradiation. This confirms the high sensitivity of triboelectric potential to aging and allows us to make a suggestion to use this parameter as an indicator of the polymeric insulation aging degree. Influence of surface charges and tribocharges on the results of diagnostic tests on the insulation resistance and stability during the measurement capacitance and dielectric loss tangent cables with polymer insulation was observed. Dynamics of changes in contact potential difference in the aging process power cables with different materials remains consistent with the results of diagnostic tests of capacity and dielectric loss tangent.
