Abstract Anion exchange membranes (AEMs) are the core components of fuel cells, playing a dual role in blocking anode/cathode and conducting OH − ions. In order to address trade‐off between ion conductivity mechanical property AEMs, imidazole ionic liquid‐grafted cellulose nanocrystals (IL@CNC) was prepared used as novel one‐dimentional nanofiller modify quaternized chitosan (QCS) polyvinyl alcohol (PVA) blend polymer matrix obtain IL@CNC/QCS‐PVA composite membranes. The uniform dispersion IL@CNC strong interaction nanofillers significantly increased tensile strength toughness. Moreover, with help 1D shape CNC together grafted groups, highly‐effective transport channels were formed inside membrane, capacity also increased, thereby sharply improving membrane containing 4% demonstrated conductivities high 29.3 76.5 mS cm −1 at room temperature 80°C, respectively, which 4.0 times 3.6 higher than those pure under same condition. as‐prepared biopolymer functionalized natural nanocellulose expected be type biomass‐based AEMs. Highlights Imidazole IL QCS‐PVA. had properties.

ABSTRACT To optimize the proton transport performance of polyvinylidene fluoride (PVdF), a exchange membrane (PEM) material, carbon nanotube (CNT), and zirconium hydrogen phosphate (ZrP) have been blended into PVdF matrix. Adopting hydrothermal synthesis route, acidic ZrP can be better conjugated with positively charged CNT functionalized by cetyltrimethylammonium bromide (CTAB). As visualized using electroscopes, nanocrystallines are intimately dotted homogeneously distributed on CNT. The ZrP–PVdF interaction attributed to bonding between hydroxyl F‐terminal groups. By incorporating well CNT/ZrP via solution casting, pore architecture regulated; namely, macro‐voids in greatly reduced. composite membranes exhibit tensile stress 48–52 MPa while sustaining thermal stability PVdF. incorporated suppress void porosity enhance film hydrophilicity.

ABSTRACT Proton exchange membranes (PEMs) with high proton conductivity, good methanol barrier ability, and reliable mechanical stability are crucial for their practical application in direct fuel cells (DMFCs). Preparation of nanofiber‐based composite PEMs is a facile effective way to balance the trade‐off between conductivity sulfonated poly (ether ether ketone) (SPEEK). Herein, surface amino functionalized silica coated polyvinylidene fluoride (N‐SiO 2 @PVDF) electrospun nanofibers were prepared used as support SPEEK. The obtained SPEEK‐filled N‐SiO @PVDF membrane showed strength (27.3 MPa) toughness aid reinforcement effect together ionic crosslinking grafted NH filling polymer Moreover, demonstrated considerable conductivities especially at 80°C (46.1 mS cm −1 ), which was very close that SPEEK (53.5 ).
