Influence of PVDF Processing Techniques on the Final Structural and Sensing Properties
Original language description
This study is focused on tha effect of differeni processing techniques of poly(vinylidene fluoride) (PVDF) sheets on its sensing capabilities. The goal of this research is to find easy and relatively cheap way of produdng PVDF sensing films. PVDF is seems to be promising material due to its excellent píezoelectríc propertíes and good flexibility dueto the presence of electroactive β-phase. By the stretching of the α-phase PVDF films, β-phase PVDF can be attained. Our prevíous studíes investigated the effect of the different molecular weight of the PVDF on the -phase development but great impact on it has also different technology of production which can be foud in industry. This research compare methods of hot pressing, blow moulding and extrusion which are common in industrial production. The transformation of the α-phase to the electro-active β-phase was analyzed using FTIR. As a complementary method, the XRD was applied, and it confirmed the data resulting from the FTIR analysis. The samples were polarized by exposing to different temperatures and electrical fields and piezoelectric charge coefficient (d33) was investigated: The most promising PVDF material and obtained d33 coefficient of our mariufactured films provide similar performance in comparison to commercially produced materials.
