Future Work

The considerable investigations of ferroelectric polymer thin films have explored new functional devices for flexible electronics industry. Polyvinylidene fluoride (PVDF) and its copolymer with trifluoroethylene (TrFE) are the most commonly used polymer ferroelectric due to their well-defined ferroelectric properties and ease of fabrication into thin films. In this study, we review the recent advances of thin ferroelectric polymer films for organic electronic applications. Initially the properties of ferroelectric polymer and fabrication methods of thin films are briefly described. Then the theoretical polarization switching models for ferroelectric polymer films are summarized and the switching mechanisms are discussed. Lastly the emerging ferroelectric devices based on P(VDF-TrFE) films are addressed. Conclusions are drawn regarding future work on materials and devices.

One of the most actual problems regarding reparation and reconditioning of ships propellers surfaces or of some parts of hydraulic machines (turbines, pumps) is that of the erosion produced by cavitation, both from technical difficulties and costs. That is why researchers and builders are searching for new cheap solutions mainly regarding these surfaces protection. The present study concerns the analysis of polymer thin films meant to protect surfaces of bronze parts exposed to cavitation. The bronze is a material frequently used to cast maritime or fluvial vessels propellers. The test, conducted at Timisoara Polytechnic University Cavitation Laboratory on standard vibrating equipment, showed the poor resistance of polymer films and revealed the necessity of continuation the studies especially in finding new techniques in order to increase the polymer films adhesion to the metallic surfaces that had to be protected.
