Title (EN) CORE-SHELL NANOFIBERS FOR CAPACITIVE SENSING AND TRIBOELECTRIC APPLICATIONS
(FR) NANOFIBRES NOYAU-ENVELOPPE POUR DES APPLICATIONS TRIBOÉLECTRIQUES ET DE DÉTECTION CAPACITIVE
Abstract:
(EN) A core-shell nanofiber having a core and a shell surrounding the core is provided, wherein the core comprises an ionogel and the shell comprises polyvinylidene difluoride (PVDF) or a copolymer thereof. In a preferred embodiment, the ionogel comprises 1 -butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][TFSI] and poly(dimethylsiloxane) (PMDS). A method of preparing the core-shell nanofiber and a device comprising the core-shell nanofiber for use in capacitive sensing and triboelectric applications are also provided.
(FR) La présente invention concerne une nanofibre noyau-enveloppe ayant un noyau et une enveloppe entourant le noyau, le noyau comprenant un ionogel et l'enveloppe comprenant du difluorure de polyvinylidène (PVDF) ou un copolymère de ce dernier. Selon un mode de réalisation préféré, l'ionogel comprend du 1-butyl-3-méthylimidazolium bis(trifluorométhylsulfonyl) imide [BMIM] [TFSI] et du poly(diméthylsiloxane) (PMDS). La présente invention porte également sur un procédé de préparation de la nanofibre noyau-enveloppe et sur un dispositif comprenant la nanofibre noyau-enveloppe destinée à être utilisée dans des applications triboélectriques et de détection capacitive.
