Fabrication of electrospun poly (methyl methacrylate) nanofiber membranes

Electrospinning superhydrophobic–superoleophilic fibrous PVDF membranes for high-efficiency water–oil separation

“…Recently, nonwoven fibrous membranes made of pure electrospun PVDF nanofibers have also been reported, which exhibited hydrophobic behavior with the water contact angle of 136 o [37]. In order to further improve the hydrophobicity of these nanofibrous membranes, inorganic nanoparticles (e.g., SiO 2 , TiO 2 and Al 2 O 3 ) have been considered to incorporate into the PVDF nanofibers during the electrospinning process [38]. However, due to the weak bonding strength between the nanoparticles and PVDF nanofibers, these nanoparticles could be easily detached from the fibers.…”

Improved electrochemical and photovoltaic performance of dye sensitized solar cells based on PEO/PVDF–HFP/silane modified TiO2electrolytes and MWCNT/Nafion®counter electrode

“…17 Variety of nanoparticles such as SiO 2 , ZnO, SnO 2 , TiO 2 , ZrO 2, etc have been employed as fillers in polymer nanocomposite electrolytes for dye sensitized solar cell applications. [18][19][20][21][22][23][24] Among them SiO 2 and TiO 2 nanoparticles were more investigated fillers for solid state DSSC electrolyte applications. The interfacial resistance of each interface (Photo anode/electrolyte/counter electrode) in DSSC plays main role in the photo conversion efficiency.…”

A Highly‐Efficient Composite Separator with Strong Ligand Interaction for High‐Temperature Lithium‐Ion Batteries

“…[5,6] Commercial separators employed in LIBs such as polypropylene (PP) and polyethylene (PE) undergo high shrinkage at temperatures above 100 8C, which causes internal short circuiting and triggers thermal runway reactions. [11][12][13] To address these issues, inorganic particles such as titanium dioxide (TiO 2 ), [14][15][16][17][18] silicon dioxide (SiO 2 ), [19][20][21] aluminium oxide (Al 2 O 3 ), [22][23][24] have been incorporated to enhance the performance of PVDF-HFP. Poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), a co-polymer of PVDF-HFP has drawn extensive interest because of its high affinity to liquid electrolyte, good chemical stability, and desirable adhesion with the electrodes.…”
