PREPARATION AND CHARACTERIZATION OF MODIFIED PIEZOCOMPOSITE MATERIALS FOR PIEZOFOAMS
Original language description
Piezoelectric materials are widely used for various applications. According to the desired application, materials of suitable chemical, mechanical and physical properties must be used [1]. One promising material is poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), which is a copolymer based on poly (vinylidene fluoride) and exhibits piezoelectric properties. To further enhance the properties of the polymer, piezoceramics with promising piezoelectric capability such as strontium titanate (ST) are used [2].This work is focused on the modification, preparation and characterization of PVDF-HFP/ST composite materials for subsequent physical foaming in laboratory autoclave. Strontium titanate was used in a neat and modified version. Modification was carried out using surface-initiated atom transfer radical polymerization resulting in a thin polymer coating made of poly(2,2,2-Trifluoroethyl methacrylate). Finally, samples of prepared materials were foamed in a laboratory autoclave using nitrogen gas as a foaming agent and fundamental characterization of such foams will be performed.
