“…This result is in contrast with previous investigations in which significant β‐phase was detected for PVDF composites based on cellulose pulps (i.e. not MFC), both with OH‐ and F‐terminated cellulose surfaces 31,32 . The reason is that in the present study the untreated MFC and F‐MFC did not disperse well in the low surface energy fluorinated polymer matrix, and therefore did not induce favorable interactions and phase transition in PVDF.…”

“…Among the studied nucleating particles, increasing attention is being paid to cellulose because it is the most abundant biopolymer on Earth and it is a low cost material with excellent mechanical properties 28,29,31–33 . Various forms of cellulose have been used to promote the formation of β‐phase in PVDF including nanofiber, nanocrystalline, microcrystalline and bacterial cellulose 32–36 .…”

“…Various forms of cellulose have been used to promote the formation of β‐phase in PVDF including nanofiber, nanocrystalline, microcrystalline and bacterial cellulose 32–36 . Some authors suggested that the hydroxyl groups of cellulose could promote heterogeneous nucleation and force the PVDF chains to crystallize into a β configuration 28,31,33 . However, PVDF and cellulose do not interact at a molecular level leading to the formation of cellulose aggregates in the polymer matrix 29,32 .…”

“…Most of the previous work on cellulose/PVDF composites were devoted to cellulose fibers and nanocrystals, with rather well‐defined morphologies and surface areas 28,29,31–33 . The present work focuses on microfibrillated cellulose (MFC), characterized by more complex fibrillar morphologies and challenging dispersion into hydrophobic polymers.…”

The effect of silylation of microfibrillated cellulose (MFC) surfaces on β‐phase formation in poly(vinylidene difluoride) (PVDF) and the resulting viscoelastic and dielectric performance of MFC‐PVDF composites is investigated. Two different organosilanes, namely aminated (A) and fluorinated (F), were used. Composites of PVDF and MFC at concentrations up to 10 wt%, both untreated and silylated, were prepared by solvent casting. The two different surface modifications did not markedly change the melting and crystallization enthalpy of the polymer. However, only A‐MFC was found to promote β‐phase compared to the untreated MFC and the F‐MFC, which was attributed to the formation of hydrogen bonds at the interface between the amine groups of A‐MFC and the fluorine groups of PVDF. The elastic modulus and the permittivity of all composites increased with the amount of MFC up to a maximum value, depending on the MFC modification, and then decreased. This effect was due to the formation of MFC aggregates and porosity, as further confirmed by a comparison of experimental moduli with a classical composite mechanical model. The highest elastic modulus and highest permittivity were obtained for the untreated MFC and A‐MFC composites with 5 and 1 wt%. © 2021 Society of Chemical Industry

Ionic liquids for the control of the morphology in poly(vinylidene fluoride-co-hexafluoropropylene) membranes

Abstract:The development of polymer membranes with tailored micro-morphology and wettability is a demand in the areas of filtration, sensors, and tissue engineering, among others. The thermoplastic copolymer poly(vinylidene fluoride-cohexafluoropropylene) (PVDF-HFP), is one of the most widely used polymers for these applications due to its good mechanical and thermal properties, biocompatibility and low density. Although the control of the PVDF-HFP morphology is a complicated task, the introduction of ionic liquids (ILs) in the PVDF-HFP matrix opens news perspectives in this area. This

Polyvinylidene fluoride (PVDF) membranes have been widely applied in the separation of various organic matters owing to their excellent properties. However, they possess low wettability and undergo fouling because of the hydrophobic nature of PVDF. In this study, poly (2‐hydroxyethyl methacrylate) (PHEMA) and poly (sulfobetaine methacrylate) (PSBMA) were co‐introduced to modify the highly hydrophobic PVDF membrane surface via UV photo‐irradiation. Facile UV photo‐grafting was performed by irradiating the pristine PVDF membrane immersed in a PHEMA/PSBMA mixture solution with UV light for 5 min. The performance of the as‐prepared PHEMA/PSBMA‐grafted membrane was compared with that of membranes modified with solely PHEMA or PSBMA. The hydroxyl and zwitterionic groups of the grafted membranes enhanced wettability and increased flux. A tightly bound water layer was formed because of the enhanced wettability, significantly suppressing protein adsorption. The initial flux of bovine serum albumin (BSA) solution through the PHEMA/PSBMA‐grafted membrane was 2861 LMH, which was 3.1 times higher than that obtained by the pristine PVDF membrane. Furthermore, the flux decline of the modified membrane caused by BSA fouling was 49% lower than that of the pristine PVDF membrane. Finally, the PHEMA/PSBMA‐grafted PVDF membrane showed antifouling properties after three BSA filtration cycles.
