| titleOfInvention | A kind of multifunctional piezoelectric nanofiber material, flexible sensor and preparation method thereof |
| abstract | The embodiments of the present invention relate to a multifunctional piezoelectric nanofiber material, a flexible sensor and a preparation method thereof. The preparation method of the multifunctional piezoelectric nanofiber material provided by the present invention comprises: combining Eu(NO 3 ) 3 ·6H 2 O or Tb(NO 3 ) 3 ·6H 2 O), TTA or DBM and Phen or TPPO or bipy Dissolve in a certain amount of absolute ethanol, adjust the pH and mix, heat, and after stirring for a certain period of time, filter and dry the obtained precipitate to obtain a fluorescent complex; dissolve PVDF or its polymer in DMF and Ac, heat Stir for a certain period of time; add an appropriate amount of the above-mentioned fluorescent complexes and additives, dissolve, and obtain an electrospinning precursor solution; electrospinning, that is, a multifunctional piezoelectric nanofiber material. Based on electrospinning technology, by adding fluorescent rare earth complexes and additives such as BaTiO 3 , FeCl 3 6H 2 O, the structure and morphology, mechanics, dielectric, piezoelectricity, etc. of PVDF or its polymer nanofibers can be improved. Fluorescence and other properties, to prepare piezoelectric functional nanofibers with excellent fluorescence properties and high β-crystal content. |
