Fabrication of TIO₂-embedded PVDF membranes and their application in algae membrane bioreactor systems
Polyvinylidene difluoride (PVDF) membranes with and without TiO2 (5% by mass) were fabricated and applied for high-density algae cultivation in membrane algae bioreactors (MBR). Microalgae species Chlorella Vulgaris was cultivated in the MBR systems fed with artificial wastewater at a target solids …

A Multi-functional Touch Panel for Multi-Dimensional Sensing in Interactive Displays
This thesis presents a flexible graphene/polyvinylidene difluoride (PVDF)/graphene sandwich for three-dimensional touch interactivity. Here, an x-y plane touch is sensed using graphene capacitive elements, while force sensing in the z-direction is by a piezoelectric PVDF/graphene sandwich. By …

Experimental and numerical investigation of cavitation erosion damage in FRP composites
… The ultrasonic cavitation field was tested using polyvinylidene difluoride (PVDF) sensors (which were manufactured and calibrated in the university laboratories) and analysed using nonlinear computational fluid dynamics (CFD) modelling. The experimental and numerical data were used in developing …

Electrospun polymer fibers for triboelectric energy harvesting applications in smart textiles
… Nylon-11, polymethyl methacrylate (PMMA) and polyvinylidene difluoride (PVDF), using electrospinning, which is a widely used, scalable fiber-production method. These materials are selected because they respectively occupy the top, middle and bottom of the triboelectric series and are thus …
