Preparation of PVdF nanofiber membranes by electrospinning and their use as secondary battery separators

Novel electrospun polyvinylidene fluoride-graphene oxide-silver nanocomposite membranes with protein and bacterial antifouling characteristics

“…The fiber size histograms [25,28,30,34,47]. For example, Hwang et al [48] reported that the porosity of electrospun PVDF mats falls in the range of 35-48%, while Coreia et al [49] reported a porosity of 79%. The factors affect electrospinning include polymer solution parameters, i.e.…”

Hollow mesoporous silica sphere-embedded composite separator for high-performance lithium-ion battery

“…To overcome the drawbacks of polyolefin-based separators, many modification approaches, such as polymer coatings [8], polydopamine treatment [9], and electrospinning method [10] have been explored. More recently, surface coatings based on organic polymers, occasionally combined with inorganic ceramic fillers, such as SiO 2 , Al 2 O 3 , TiO 2 , and ZrO 2 , have attracted substantial attention because of their simplicity, effectiveness, and processing versatility [11][12][13][14][15][16].…”

Electrospun Nanofibers for Sandwiched Polyimide/Poly (vinylidene fluoride)/Polyimide Separators with the Thermal Shutdown Function

“…Various electrospun membranes from different polymer materials have been attempted as separators to successfully achieve low thermal shrinkage and improved electrolyte uptake, including thermoplastic polyurethane (TPU) [12], polyacrylonitrile (PAN) [13], Poly(vinylidene fluoride) (PVDF) [14], poly(vinylidene fluoride co-hexafluoropropylene) (PVDF-HFP) [15], polyethylene terephthalate (PET) [16] and polyimide (PI) [17]. Trilayer separators basing on electrospun nanofiber membranes have been also explored to further improve the thermal shrinkage and electrochemical performance [18][19][20].…”
